Adaptive reuse is the reuse of an existing building for a purpose other than that for which it was originally built or designed. It is also known as recycling and conversion. The adaptive reuse of buildings can be a viable alternative to new construction in terms of sustainability and a circular economy, and it has been used to create affordable housing, among other developments.

Definition

Adaptive reuse is defined as the aesthetic process that adapts buildings for new uses while retaining their historic features. Using an adaptive reuse model can prolong a building's life, from cradle-to-grave, by retaining all or most of the building system, including the structure, the shell and even the interior materials. This type of revitalization is not restricted to buildings of historic significance and can be a strategy adopted in case of obsolete buildings.

Some urban planners see adaptive reuse as an effective way of reducing urban sprawl and environmental impact. Revitalizing the existing built fabric by finding a new use or purpose for obsolete buildings can be a wonderful resource to a community by "keeping neighborhoods occupied and vital".

According to Yung and Chan, "adaptive reuse is a new kind of maintainable rebirth of city, as it covers the building's lifetime and evades destruction waste, encourages recycles of the embodied dynamism and also delivers substantial social and economic profits to the world".

Benefits and challenges

Benefits: Typically categorised under economic, social, cultural and historical, and environmental benefits. The most significant benefits of adaptive reuse of existing buildings include increased economic opportunities, urban regeneration, preserved cultural and historical heritage values, reduced landfill demolition waste, increased energy efficiency, extended building usefulness, and cost-effectiveness, enhanced property value, improved life quality, reduced carbon emissions, and lesser energy consumption.

Challenges: Typically categorised under building regulatory requirements and governance, financial, management, and complexities and uncertainties challenges. The most significant challenges of adaptive reuse of existing buildings include structural integrity issues, compliance with building code regulations, government anti-adaptive reuse policies, lack of awareness, high maintenance cost, uncertainties surrounding existing building information, lack of incentives, and lack of decision-making tools and stakeholder participation.

Adaptive reuse and preservation

A majority of historical buildings provide physical links and the progression of cultural evidence to the past. Built heritage conservation through adaptive reuse could therefore be used to promote sustainable historical and cultural development of urban areas. Parameters to prioritise historical buildings for adaptive reuse and the characterisation of adaptive reuse stakeholders are also noted.

Adaptive reuse and urban regeneration

The reuse of older vacant buildings for other purposes forms a very important aspect of any urban regeneration scheme. Adopting the adaptive reuse approach for the redevelopment of older vacant buildings provides added benefits to the regeneration of an urban area in a sustainable way, through transforming these buildings into usable and accessible units. The adaptive reuse strategy would also enable the local authority and owners of older vacant buildings in urban areas to minimize their economic, social and environmental costs, in a quest for a continued urban expansion and development.

Adaptive reuse and climate change

The current climate change reality requires integrating the global sustainability challenge of conserving natural resources for future generations with improving resilience and adaptive capacity within the built environment. The adaptive reuse of existing buildings can be adopted to facilitate climate change mitigation progressively. explored the applicability of the adaptive reuse concept as a sustainable tool for climate change mitigation.

Adaptive reuse stakeholders

In an adaptive reuse decision-making setting, there is usually an occurrence of conflicting beliefs, opinions, interests, and resources among relevant stakeholders. Knowing who these stakeholders are and why, through a collaborative approach, will allow stakeholders with diverse interests regarding adaptive reuse to come together and participate either directly or indirectly in any stage of the decision-making process. There are four typical categories of stakeholders involved in an adaptive reuse decision-making process: i) investors; ii) producers; iii) regulators; and iv) users.

Adaptive reuse framework

Identification of Parameters: identified parameters for the development of a performance-based framework, to prioritise the most suitable historical building options for adaptive reuse intervention from a list of underutilised buildings.

Framework Validation: balanced the diverse interests of all stakeholders in the adaptive reuse decision-making process.

Advantages of adaptive reuse

According to Zaitzevsky and Bunnell, old buildings physically link us to our past and become a part of our cultural heritage; they should be preserved because of their "architectural beauty" and the "character and scale they add to the built environment". Retention and rehabilitation of existing buildings also reduces the consumption of building materials, resources, energy and water needed for new construction.

• Cost savings on building material: Adaptive reuse involves the refurbishment of existing building members, which is labor-intensive process and relies less on purchasing and installing many new building materials. Cost of building materials has risen sharply over the past few decades, while the cost of labor has increased only marginally compared to that of building materials. Therefore, it is economically viable to renovate and reuse an existing building.
• Cost savings on demolition: Demolition costs can run as high as 5% to 10% of the total cost of new construction. This expense is often overlooked by many building owners. Some urban areas have strict building safety regulations and may not allow the usage of a swinging ball and other more efficient demolition techniques. Under these circumstances, buildings must be demolished piece by piece, which can be quite expensive and time-consuming.
• Saves time; faster than brand new construction: The total time required to renovate an existing building is generally less than the time required to construct a comparable amount of floor space in an entirely new building. A major advantage of renovating an existing building is that a refurbished portion of the building becomes suitable for occupancy before completion of the whole project. This provides as a huge advantage for private developers as it keeps the cash inflow while the rest of the project undergoes construction.
• Tax advantages: Tax provisions in several states and municipalities across the United States, provide incentives for rehabilitating historic structures.
• Availability of Federal, State and local funds: The United States' National Historic Preservation Act of 1966 established matching grants-in-aid, obtained through state historic preservation offices, that can be used for the acquisition and restoration of properties listed in the National Register of Historic Places. Similarly, community development block grants provided to municipalities by the U.S. Department of Housing and Urban Development are a major source of funds for neighborhood preservation projects.
• Decreased public and social costs: As these heritage settlements have been getting crowded in the past decades, people have been looking for farther lands for development. This rapid urbanization and urban sprawl cause several harms to our planet and the society. Lack of adaptive reuse of existing built assets, on a societal level, has caused disturbance due to dislocation of residents, economic decline and disruption of community life, eventually leading to abandoned and obsolete neighborhoods.
• Conserves energy: Modern building systems have high life-cycle costs and operational energy costs associated with them whereas traditional masonry and stone buildings are more climate-responsive. An environmental benefit of reusing built assets is identified to be the retention of the original buildings "embodied energy". According to Schultmann and Sunke, "new buildings have much higher embodied energy than those that are adaptively reused". Reddy and Jagadish support this statement by saying that "the reuse of building materials can provide substantial savings in embodied energy that would otherwise be wasted".

Relevant factors

Building owners, architects, developers and other stakeholders undergo an in-depth process of decision making before determining whether a building should be conserved and remodeled for a different use or just demolished for the land it sits on, then develop a new building on that land. These decisions are governed by the following criteria:

Economic considerations

The Kelso Home for Girls in Baltimore, Maryland was a typical candidate for adaptive reuse, but it was razed to accommodate parking for a new athletic facility when the cost of conversion was found to be too great

The decision to reuse or demolish built assets is driven by economic considerations such as development costs, project costs, investment returns and market. The economic costs differ from project to project and some professionals go as far as to assert that "new build is always more economical" and "renovation is universally more expensive"^[1] due to their own involvement with adaptive reuse projects.

Capital investment

In a survey conducted by Bullen and Love, it was observed that building owners and operators were most concerned about a multitude of financial considerations, while deciding whether to reuse their built assets. These include development and construction costs, marketing and maintenance costs. Most adaptive reuse projects depend on their economic feasibility determined by the building's existing physical configuration and condition. According to Bullen and Love, the adaptive reuse decision making was fundamentally driven by a "desire for short-term profits". However, most of the survey respondents were rarely concerned about the sustainability and environmental concerns associated with adaptive reuse decision making. Nevertheless, many of these developers were aware of the positive impact that building reuse and sustainability can have on their corporate image.

Building owners are concerned with the life expectancy of built assets, their energy and environmental performance and the high operating costs which may appear due to poor mechanical equipment, services, building materials and construction. Developers saw a thorough potential in saving groundwork and excavation costs by using an adaptive reuse model for their property. Additionally, they thought that "in Central Business District locations, built assets are an attractive investment option for reuse projects, as premium prices and rents can be obtained for an office space". Best rents can be obtained only when these remodeled buildings hold "high-quality finishes" and have high Energy Star rating appliances. Building owners also considered the commercial performance of buildings in terms of "tenant needs, investment returns, maintenance, repair costs, operational costs, productivity levels, employee retention rates, aesthetics of building and its market value".

Building stakeholders often marketed their reused built assets centered around "epoch and utility" and "character and ambiance". Some end users were more attracted to modern architecture while others were more into the adaptive reuse style. This varying perception of a building's form, function and style depended on the occupant age group.

Asset condition

Sometimes, built assets cannot be considered suitable for adaptive reuse, simply because of the nature of their built form or the condition that they are in. For example, one cannot make the most out of a highly compartmentalized, single use building such as a prison. Mid 1900s low-rise apartments that have low floor area ratios (FAR) and which may be in some of the cities' prime locations cannot be considered profitable for adaptive reuse. In such scenarios, it would be more profitable for the developers to demolish and replace the existing building with a high-rise that has more space to sell. Often, when building owners cannot find an obvious use for a building, it is left to degenerate and decay and eventually collapse. This may pose as a threat to the safety of the neighborhood. Decaying buildings may even be subject to vandalism and become spaces for anti-social activities and may have a negative impact on the value of the properties in their vicinity.

Bullen and Love's survey respondents thought that "the benefits of reusing their existing facility could include avoiding the disruption of relocation, reducing maintenance and running costs". A reuse project should not compromise on satisfying user needs. The survey respondents suggested that a cost vs benefits analysis is essential to determine the return on investment of an adaptive reuse project. The most important governing factors of adaptive reuse decision making with respect to asset condition were observed to be the building's structural integrity, its residual service life, its spatial layout, its location and the ease of retrofitting or installing new building components to the existing built form. According to Bullen and Love, the buildings of the 1960s and 1970s in Perth were badly constructed, used ineffective thermal insulation materials and details and have low suitability for adaptive reuse. On the other hand, the built form of the 1980s was deemed to be engineered to specifications and could accommodate an adaptive reuse model.

The survey respondents expressed several concerns and risks that could arise during and after the adaptive reuse of a building which included finding tenants, the threat of building not meeting the demand of the end users, lack of structural stability and structure and material decay during the reconstruction phase of the project.

Regulations

In Bullen and Love's survey, many respondents thought that there was not enough support and incentives from the government for carrying out adaptive reuse of built assets. They felt that there is limited flexibility in the building codes, limited plot ratio bonuses and an overall "lack of encouragement" by state and local governments to implement innovative adaptive reuse designs. Suggested solutions from some survey respondents include establishing a mandate to only lease buildings that have undergone adaptive reuse with a high Energy Star rating. Some of the architects thought that there was a high dependency and credit given to energy and green building rating systems such as the "Green Star Environment Rating System" but not enough credit was given to the improvements carried out during adaptive reuse and its sustainable outcomes such as the recycling of building materials, reduced energy and water consumption and reduced environmental impacts like global warming potential, lake eutrophication potential and ozone layer depletion. One architect thought that "undertaking exemplar adaptive reuse demonstration projects for industry professionals to assess and emulate would display a commitment to sustainability and urban regeneration". However, this solution has several harmful implications and forcing an adaptive reuse directive on to the industry and its clients was deemed to be heavy handed and could be counterproductive. The existing building codes and regulations for fire safety and building access to disabled make it difficult to work around the adaptive reuse of old constructed buildings.

Social considerations

In this civilized world, buildings have become the core of a society. Cities and communities grow organically around important buildings followed by the commercial development of those neighborhoods. These buildings and the development around them soon become the heart of a community upon which people's life depends. Therefore, regular maintenance and reuse of existing structures can help communities avoid the trauma caused by dilapidation, abandonment and clearance.

As these heritage settlements have been getting crowded in the past decades, people have been looking for farther lands for development. This rapid urbanization and urban sprawl cause several harms to our planet and the society. Lack of adaptive reuse of existing built assets, on a societal level, has caused disturbance due to dislocation of residents, economic decline and disruption of community life, eventually leading to abandoned and obsolete neighborhoods.

Old buildings are often found in fully developed neighborhoods where public amenities like sewers, water lines, roads, etc. have already been established. Adaptive reuse means that the stakeholders of the built asset are relieving governments and municipalities off the load of having to supply these public amenities on distant plots.

In a survey conducted by researcher Sheila Conejos, several architects, developers and building stakeholders were asked about their opinion on the social implications of adaptive reuse of existing buildings. It was observed that most respondents thought that adaptive reuse is important to the society because old buildings are critical to the image and history of a society. They agreed that historical buildings add to the aesthetics of a townscape and should be preserved and reused.

Adaptive reuse potential

According to Chusid's "urban ore" concept, existing buildings that are fast approaching dilapidation or disuse are a "mine of raw materials for new projects". Shen and Langston built upon this idea and said that "an even more effective solution than raw material recovery is adaptive reuse". They studied that "a huge focus on economic factors alone has led to the destruction of buildings well short of their physical lives". Shen and Langston developed an integrated model for the assessment of adaptive reuse potential by comparing case studies of one urban and one non-urban setting. The basis of this model lies in that "opportunity rises and falls within the confines of a negative exponential decay function linked to a building's physical life expectancy". According to their study, a building reaches its maximum potential for adaptive reuse at a point when the building's age and its useful life merge or meet. At this point, the building's adaptive reuse potential is either an upward curve or a downward curve which can determine whether the potential is high, medium or low.

The adaptive reuse potential calculator establishes a "predicted useful life" of a building by considering a series of physical, economic, functional, technological, social, legal and political characteristics. These characteristics are used to derive an "annual obsolescence rate" and "environmental obsolescence". These outcomes are necessary to determine an optimum point at which adaptive reuse intervention should occur.

An algorithm based on a standard decay (negative exponential) curve produces an index of reuse potential (known as the ARP score) and is expressed as a percentage. This decay curve in buildings can be used to establish an ARP score, which is expressed in percentage. Cities can rank their existing buildings as per their adaptive reuse potential and this data can be used by government authorities at any point in time. An adaptive reuse score of 50% or above is considered high. A low ARP score is anything below 20%. Anything between that range is considered moderate. Shen and Langston devised this concept of ARP as "rising from zero to its maximum score at the point of its useful life, and then falling back to zero as it approaches physical life".

Methodology

Buildings have a high impact on the environment, the economy and our society. Adaptive reuse has several benefits to mitigate those high impacts. Adaptive reuse projects are, in many ways, different from conventional new construction projects and must be planned and managed differently.

Building condition assessment

Before starting an adaptive reuse project and even considering refurbishment, it is important that the condition of the existing building is thoroughly assessed. A condition assessment primarily inspects a building's structural integrity, roofing, masonry, plaster, wood-work, tiling and the mechanical, electrical and plumbing systems. The in-depth inspection of buildings can be expensive. Nevertheless, building condition assessment is critical to the success of an adaptive reuse project and must not be avoided at any cost because this expense is insignificant relative to the injury or loss of life that a building failure might cause. One logical reason, as explained by the American Society of Civil Engineers, is that even a very well constructed building could undergo serious deterioration and eventually failure, if proper maintenance is not performed in the operational phase of the building. The direct inspection of the structural system is required to a certain degree which is decided by the judgement of an experienced civil engineer.

Survey of neighborhoods

After identifying the stability and soundness of a building, it is important to survey the neighborhood to find the potential use and function of the adaptive reuse project for that segment of the market or region that the building owners wish to attract. In many cases, an adaptive reuse project might help stabilize a neighborhood which may be otherwise decaying or be at a threat of vandalism. This upward trend may create lucrative rent opportunities for building owners and dwellers of the neighborhood. This survey can be in the form of a physical inspection of the neighborhood and/or a detailed study of the zoning map of that region. Pedestrian activity, presence of sidewalks, street lights, benches and public parks and the presence of well-occupied shops and buildings can tell us a lot about neighborhoods. After the neighborhood has been established to be stable and safe and free of any infringing decay, the next step is to determine what amenities it has to offer in terms of roadways, public transportation, shopping and eating, hospitals, schools and libraries and so on.

Financial considerations

As discussed previously, adaptive reuse projects have the potential to work in phases or parts. A major advantage of renovating an existing building is that a refurbished portion of the building becomes suitable for occupancy before completion of the whole project. This provides as a huge advantage for private developers as it keeps the cash inflow while the rest of the project undergoes construction. Keeping in mind the conclusions from structural and architectural survey, neighborhood survey and marketing survey, a budget is prepared. Building owners or developers can approach any of the financing sources such as insurance companies, foundations and funds, savings banks, building loan societies, endowment funds, Real Estate Investment Trusts, etc.

Architect's contract

In most adaptive reuse projects, it is the architect who is the leader with the imagination of how an abandoned warehouse can become an office building or an abandoned hospital a condominium. Since the architect has a deep involvement in the success of a project, he must perform his work under a clearly defined contract. Under this contract, the architect and the owner are under the obligation of the contract and must abide by it. Progress of design, site visits and evaluation are some of the basic actions that the architect performs under this contract. There are different types of contracts, ranging from a fixed fee contract, percentage of construction cost contract and fee plus expenses contract. All stakeholders may collectively decide on the most suitable type of contract for the project.

Detailed study of structure

Before the architect and engineer begin the final designing for the building, they make a thorough structural, mechanical and architectural survey of the existing building.

Foundation and basement

The architect and engineer may look for signs of cracking of masonry wall or the settling of basement floors or upper floors which direct them to a problem in the foundation. These signs can also be detected from window sills and cornices. Appropriate survey instruments such as plumb bobs and spirit levels are recommended for use instead of a naked eye inspection. If the problem seems too severe, a test boring may reveal the cause of the problem. Additionally, the building code should be examined for fireproofing requirements.

Structural system

Analyzing the structural strength requires expertise and is one of the most crucial in terms of occupant safety. On-site inspection along with a study of existing floor plans can help engineers determine the structural stability. In some case, when the building drawings may not be available, engineers may have to scrape off the plaster to reveal the underlying structure. Wooden members of the structural system should be especially checked for rot or termite infestation. Iron or steel must be checked for corrosion and loose bearings or bolting. Additional future dead and live loads must be kept in mind while designing with the structural strength of the existing building.

Floor system

The floor system in old buildings is usually strong enough to satisfy present codes. If not, additional supporting members may be necessary. The floor and ceiling height should be able to accommodate additional stairways, vertical plumbing, electrical and HVAC. In some cases, an elevator may have to be installed.

Exterior walls

The building envelope should be examined thoroughly for cracks, watertightness (infiltration or leaks) and mortar joints. It is important to examine these exterior walls for future fenestration and air conditioning ducts.

Roof and waterproofing

Older building roofing systems generally comprise the roof, parapets and cornices. Projecting metal cornices are subject to corrosion. Parapets may be subject to cracks and degrading mortar joints. A careful examination of the top-floor ceiling may reveal water leakage.

Stairways and exits

The stairway requirement for a building should be derived from present-day building codes for fire and safety. Strategic placement of new staircases and layout for maximum access should be done in order to maximize space utility and minimize the burden on the structural system.

Designing to save energy

Redesigning the existing building for new use must accommodate energy conservation strategies. Some of the most important methods of energy conservation are, reducing heating and cooling loads through building envelopes, maximizing natural ventilation potential, using daylighting and energy efficient lighting fixtures and so on.

Building envelope

A building's envelope protects it from the external weather conditions. To prevent the extreme climate of the exterior from causing discomfort to occupants, buildings use mechanical heating and cooling systems. If the building envelope is not designed well, the heating and cooling loads on the mechanical equipment might go high. Therefore, for maximum energy efficiency, building envelopes should be the first layer to block out external weather conditions, then the load on the equipment can be minimized. The U value of walls should not be more than 0.06 when winter design temperatures are less than 10 °F (?12 °C). This can be achieved by using a combination of exterior wall materials to form a high resistance wall assembly.

Windows and doors

The fenestration in an external wall assembly are the biggest wasters of energy. They waste heat by conduction, radiation and infiltration. This can be controlled to an extent by using multiple layered glazing systems and using low-e coatings on the glass. Additionally, it is important to seal the window and door systems to avoid infiltration. Similarly, in hot and sunny climates, it is important to shade windows to avoid heat gain due to solar radiation.

Roof

An exposed roof is the greatest source of heat loss during cold months and heat gains during hot months. Therefore, roof insulation becomes very crucial in extreme climate conditions. Another passive technique is to separate living spaces from roof by adding dead buffer spaces such as attics under the roof.

Floor

The only floor that need be considered is the bottom floor. It may be a slab on grade or built over a crawl space. In these cases, insulation should be considered. If the perimeter of a slab on grade is insulated from the weather, this is all that can be hoped for. Over a cold crawl space, a two-in blanket under the floor will cut the heat loss by at least 50%. A concrete floor slab can be insulated by sprayed-on insulating material.

Disassembly sequence planning

Building owners and developers can take the potential advantage of adaptive reuse by taking away components from unused buildings and then repair, reuse or recycle its constituent parts. Disassembly is a form of recovering target products and plays a key role to maximize the efficiency of an adaptive reuse project. This disassembly planning sequence aims to reduce the environmental impacts caused due to demolition using a "rule-base recursive analysis system" with practical and viable solutions.

By location

Americas

Canada

As a comparatively young country, adaptive reuse is not the norm in Canada, where redevelopment has typically meant demolition and building anew. Calgary and Edmonton are particularly known for their pro-demolition culture, but they are not unique in this regard. However, since the 1990s, adaptive use has gained traction. The conversion of former railway-centred warehouse districts to residential and commercial uses has occurred in Edmonton, Calgary, Saskatoon, Regina, and Winnipeg.

Toronto's Distillery District was a former whiskey distillery

In Toronto, the Distillery District, a neighbourhood in the city's southeast side, was entirely adapted from the old Gooderham & Worts distillery. Other prominent re-uses include the Candy Factory on Queen Street West and the Toy Factory, in the city's Liberty Village district, both designed by Quadrangle Architects, a firm specializing in adaptive re-use in Toronto and elsewhere. Vancouver's Yaletown, an upscale neighbourhood established in the 1990s, features warehouses and other small-industrial structures and spaces converted into apartments and offices for the gentrification of the area. Vancouver's Granville Island also demonstrates a successful mix of adaptive reuse as well as retention of traditional uses in the same district. Montreal's Griffintown, Old Port, and Lachine Canal areas all feature ex-industrial areas that have been reused or will do so in the future on current plans.

Other noted adaptive reuse projects in the 2010s have included the Laurentian School of Architecture in Sudbury, which is incorporating several historic buildings in the city's downtown core into its new campus, similar to the downtown campus of NSCAD University in Halifax, and Mill Square in Sault Ste. Marie, an ongoing project to convert the derelict St. Mary's Paper mill into a mixed-use cultural and tourism hub.

A number of former military bases in Canada, declared surplus in the 1990s, have also proven to be opportune for adaptive reuse. An example is the former CFB Cornwallis in rural Nova Scotia which was largely converted, without demolitions, into a business park.

United States

Pratt Street Power Plant in Baltimore, Maryland, United States, converted into retail, restaurants, and offices.

The Western Metal Building as seen during a game.

Ghirardelli Square in San Francisco was the first major adaptive reuse project in the United States, opening in 1964. Urban waterfronts, historically used as points for industrial production and transport, became popular as residences and mixed use. The greatest value of the adaptive use movement is characterized by the hundreds of abandoned schools, factories, hotels, warehouses and military posts that have been adapted for use as affordable housing, office buildings, as well as commercial, civic, educational and recreational centers.

A large number of brick mill buildings in the Northeast United States have undergone mill conversion projects. In the United States, especially in the Northeast and Midwest, loft housing is one prominent result of adaptive reuse projects. Formerly-industrial areas such as the Meatpacking District in New York City, Callowhill in Philadelphia and SoMa in San Francisco are being transformed into residential neighborhoods through this process. This transformation is sometimes associated with gentrification. Station Square in Pittsburgh Pennsylvania is an example of a mile-long former Pittsburgh and Lake Erie Railroad terminal and headquarters being converted into a retail, office, hotel, and tourist destination. The Pratt Street Power Plant in Baltimore was converted to offices, retail, and restaurants. An example of adaptive reuse conversion to office/business space are the Hilliard Mills. The adaptive reuse of Empire Stores will transform seven abandoned coffee warehouse in Brooklyn Bridge Park in New York City into office, retail, restaurant and a rooftop public park.

Other museums adapted from old factories include "MassMOCA", the Massachusetts Museum of Contemporary Art, the Watermill Center in Long Island, New York, and The Dia Art Foundation Museum in upstate New York.

In San Diego, California, the historic brick structure of the Western Metal Supply Co. building was preserved and incorporated into the design of Petco Park, the ballpark of the San Diego Padres.

Chapman University in the city of Orange, California has created student housing by converting the Villa Park Orchards Association Packing House, which was built in 1918 for the Santiago Orange Growers Association. The student housing complex opened in August 2018.

A Shell station in Columbus, Ohio in 2020. The building, which formerly housed a service station, was converted into a convenience store.

Throughout the United States until the 1970s, the vast majority of gas stations also offered mechanical work. Converting the service bays into a convenience store in the 1980s and 1990s was common while still selling fuel. Many others stopped selling fuel and became shops or offices.

Office-to-residential conversions are also common in the United States with office blocks in New York City, Washington, DC, and San Francisco slated for conversion to reduce the stock of vacant office blocks while addressing a housing shortage. Adaptive reuse has been identified as a viable solution to the U.S. affordable housing crisis, particularly in urban areas.

Australia

The Malthouse apartments in Richmond, Melbourne, Australia is a conversion of a former grain silo by Nonda Katsalidis.

In Australia, there have been a number of adaptive reuse projects as the main cities have turned from industrial areas into areas of high value and business areas. In Sydney, sites such as the old Sydney Mint have been renovated and adapted into inner-city headquarters for the Historic Houses Trust of New South Wales. The movement of the city from an industrial, working class area into a gentrified area with high home prices has helped a number of adaptive reuse sites to exist within such an area. The old Hyde Park Barracks building has also been transformed from an old jail into a museum which documents and records the history of Australia's first settlers and convicts.

The industrial history of Australia has also been an influencing factor in determining the types of buildings and areas which have gone on to become adaptive reuse sites, especially in the realms of private residences and community based buildings. Some such sites include, Nonda Katsalidis’ Malthouse apartments in Richmond, a conversion of a former grain silo and the South Australian site of the Balhannah Mines which was adapted into a private residence and has received awards from the Housing Industry Association and the Design Institute of Australia.

In Adelaide four prominent, heritage listed 19th-century buildings in poor repair were restored, refurbished and given new roles by the South Australian Government during the Rann government (2002 to 2011). The Torrens Building in Victoria Square, former headquarters of the Registrar-General, was restored and adapted to become the Australian campus for both Carnegie Mellon University and University College London. The former Adelaide Stock Exchange building was purchased, restored and adapted to become the Science Exchange for the Royal Institution Australia and the Australian Science Media Centre. The Torrens Parade Ground and building were restored for use as a headquarters for veterans' organisations. Nearly $50 million was committed to restore and adapt the large Glenside Psychiatric Hospital and precinct as the new Adelaide Studios of the South Australian Film Corporation opened by Premier Rann in October 2011. And the 62 hectare former Mitsubishi Motors plant is being adapted to become a clean manufacturing centre and education and training hub for Flinders University and TAFE.

Europe

The Bankside Power Station in London was converted for use as the Tate Modern. Shown is the former turbine hall, used to house exhibits.

In Europe, the main forms of adaptive reuse have been around former palaces and unused residences of the different European royal families into publicly accessible galleries and museums. Many of the spaces have been restored with period finishes and display different collections of art, and design. In Paris, France, the most famous example of adaptive reuse is the Musée du Louvre, a former palace built in the late 12th century under Philip II and opened to the public as a museum in 1793. Also, in London, England, the Queen's House, a former royal residence built around 1614, has become part of the National Maritime Museum and houses the museum's fine art collection.

The Tate Modern, also in London, is another example of adaptive reuse in Europe. Unlike other adaptive reuse galleries in Europe, however, the Tate Modern takes full advantage of the site of the former Bankside Power Station, which involved the refurbishment of the old, abandoned power station. The wide industrial space has proven to be a worthy backdrop to modern art, with the famous turbine hall hosting artworks by artists including Olafur Eliasson, Rachel Whiteread and Ai Weiwei.

London is also home to many office-to-homes conversions following a March 2024 relaxation of planning rules to facilitate such conversions. As of January 2025, 121,000 flats were created in England under “permitted development rights” (PDR) which allows developers to convert commercial buildings without full planning consent and no affordable housing requirement.

Other famous adaptive reuse sites in Europe include the Maastricht branch of the Selexyz chain in the Netherlands. This project received 2007 Lensvelt de Architect interior design award for its innovative reuse and is number one on The Guardian's worldwide top ten bookstores list.

In ?ód?, Poland, the Izrael Poznański mills have been turned into the 69-hectare (170-acre) Manufaktura mixed-use development, including a mall, 3 museums, multi-cinema and restaurants.

Asia

Hong Kong

Mei Ho House in 2013

The Hong Kong government launched the Revitalising Historic Buildings Through Partnership Scheme in 2008. One of the buildings in this scheme is former public housing Mei Ho House, which was converted to a hostel managed by Hong Kong Youth Hostels Association.

Taiwan

In Taichung, Dawn Cake bought the former ophthalmology hospital and converted it into a restaurant.
