Adaptive Reuse of Old Industrial Buildings as a Sustainable Practice in Urban Development

By Pascal Hartmann, Frank Krueger, Chen Yiping & Wang Fang

INTRODUCTION

One of the great contemporary challenges is to lead China’s cities onto a more sustainable path.China’s cities are unsustainable in their current condition, which is to say that they won’t endure in the form they exist today. Being unsustainable the current status of cities in China is a threat to the progress of society. This is not surprising, considering the circumstances: China is a quickly developing country and has to deal with the biggest urban migration in the history of mankind. The cities of China are in transition and there is no easy solution for making them more sustainable. Instead, a whole bundle of strategies has to be applied in the future, some of which are already in use. In this article we will argue that adaptive reuse of old industrial buildings is such a sustainable strategy. The conversion of old factories and warehouses into office space for creative and cultural industries has already proven to be successful in cities like Shanghai and Beijing. In this article we will explore the potential of adaptive reuse in terms of sustainability and advocate that adaptive reuse becomes a common practice in China’s urban development.  Adaptive reuse is the process of reutilizing old buildings for a new usage. Adaptive reuse is a mode of renovation, but has to be distinguished from other modes of renovation, like building modernization and historic preservation. Hitoric preservation means to restore a heritage site in order to maintain the historic and cultural value of the site. The Forbidden City in Beijing, the Bund in Shanghai and the Great Wall of China are such monuments with historic value. They are of importance to the cultural identity of a country and give people orientation and perspective. Adaptive reuse also sustains old structures but the preservation of the past is a secondary – yet sometimes very important – objective. Modernization on the other hand has the purpose of maintaining an existing building in order to bring it up to date, for example by installing modern heating systems, replacing old windows or by improving the building envelope. Building modernization is essential when it comes to increasing the life span of a building. Adaptive reuse means the modernization of an existing building plus the adaption of the buildings to a completely new usage.
Today adaptive reuse is a worldwide practiced mode of architecture. Any building can be reutilized and adaptive reuse takes many forms: Churches are turned into restaurants, old train wagons and disused silos are reused as homes, factories are converted into concert halls, and former hospitals are turned into hotels or office buildings. In this article we will discuss some outstanding international examples of adaptive reuse, and we will discuss the conversion of old factories and warehouses in Shanghai.

PART ONE: THE CONNECTION BETWEEN ADAPTIVE REUSE AND THE CULTURAL SECTOR

In Europe old industrial spaces have been reused and adapted for cultural purposes since many years. Old warehouses have been reutilized as theaters, art galleries, museums, concert halls, libraries, etc. In many European cities a close connection between reutilized industrial buildings and culture exists, manifest in culture clusters, located in former industrial buildings. We will explore this remarkable connection by investigating two of the most popular adaptive projects: Tate Modern Art Gallery in London and Zeche Zollverein Culture Park in the Ruhr area of Germany.

TATE MODERN ART GALLEY

Tate Modern Art Gallery on the south bank of the Thames in London, just across St Paul’s Cathedral, might be the most famous adaptive reuse project in the world. Tate Modern is located in the building of the former Bankside Power Station, which was designed by Sir Giles Gilbert Scott and generated electricity from 1952 to 1981. The building is 200 meters long, has a steel frame structure and is cladded with brick. A 99 meters high chimney in the centre of the building is the characteristic element. The power plant was closed in 1981 and was threatened to be demolished, until it was decided in 1994 that Tate Modern would move here. The reutilization concept was developed by Herzog & de Meuron, the architecture firm that also designed the Bird’s Nest in Beijing. With 4.7 million visitors a year, Tate Modern is the most popular modern art gallery in the world.

The most impressive space of the Tate Modern Art Gallery is certainly the former Turbine Hall, which once housed the electricity generators of the power plant. The hall is five stories tall and has an open floor area of 3400 square meters, probably the most spacious exhibition room in the world. The hall has set the scene to some of the most impressive modern art installations in the past years. From October 2002 to April 2003 Anish Kapoor displayed his monumental Marsyas project in the hall. One year later Ólafur Elíassonn installed his famed Weather Project, an artificial sun that submerged the hall in a warm and sublime light. These highly popular installations were tailor made for the dimensions of the hall and they wouldn’t have existed were it not for the spacial lavishness of the former turbine hall. It is very unlikely that any architect would propose such a space in any newly built art gallery today, which pinpoints a quality of adaptive reuse projects. Adaptive reuse leads often to interesting and rather surprising results, as the example of Tate Modern shows.

Architects follow – if they know it or not – the rationale of their time. Design proposals must be feasible and compelling. This limits the design of buildings significantly and ties them to the economical conditions of their time. Yet a different rationale is entering the design
process when old structures are reutilized. The architecture of adaptive reuse is the art of connecting the old and the new, the past and the present. The worst examples of adaptive reuse are those where this dialog fails and the old and the new don’t connect; the best examples are those where it leads to new and unexpected results. In this respect, adaptive reuse can be looked at as the entry point of a unique form of architecture into the urban sphere.

ZECHE ZOLLVEREIN

Adaptive reuse projects can be of social and cultural significance, as the following example, the revitalization of the former coal mine industrial complex Zeche Zollverein in Germany, will demonstrate. Zeche Zollverein is located within the Ruhr area, Germany’s traditional industrial belt; the site began operation in 1847. Zeche Zollverein is comprised of many buildings, widespread over an extensive area of 100 hectares. Some buildings feature outstanding architecture, shaft 12 for example is an early masterpiece of the Bauhaus style, and the 55 meter high winding tower is an icon for the whole region. But in the 1970s the decline of the region began as coal and steel production became uneconomic. When Zeche Zollverein shut down in 1986, many thought of it as the end of an era. Unemployment was high as the region struggled to find a new direction and a new identity.

Zeche Zollverein became a national heritage site immediately after it was closed in 1986, and was declared a UNESCO World Heritage site in 2001. Today Zeche Zollverein is a multifunctional culture park with museums, event halls, restaurants, schools, offices, open air fairs, sport facilities, galleries, exhibition areas, and so on. Famous architecture studios, like Foster & Partners and Sanaa contributed to the adaptive reuse design of the site. The design has been done with much respect for the industrial heritage, but also features a strong contrast of old and new, the typical element of adaptive reuse. The school of management for example, designed by Sanaa, is a postmodern white concrete cube with an irregular window pattern, a stark contrast to the dark brick walls of the industrial buildings. The site of Zeche Zollverein is today among the most popular places in the Ruhr area and attracts millions of visitors every year.


Zeche Zollverein was not just an isolated reutilization project, but had significance for the whole region. Here was a monument of the past, a reminder and icon of the industrial culture of the whole region, which was reutilized to become a symbol of the post-industrial era. The diverse mix of functions is not only a feasible solution for this site, but shows the new economic direction for the whole region. The Ruhr area is now developing in the direction of innovation, education and culture. It is noteworthy, that such integration of the past into the present with a signal effect for a whole region can only be achieved by revitalizing old buildings.

ADAPTIVE REUSE AND CULTURE

What is the reason for the connection between adaptive reuse projects on the one hand and the cultural sector on the other hand? The obvious answer is pragmatic: the openness of industrial spaces is a perfect fit for the cultural sector; as such spaces can be easily used for exhibitions, workshops and studios. But we believe another answer has to do with the architectural style of adaptive reuse itself. Adaptive reuse projects are – if they are done right – never boring. In the architecture of adaptive reuse a dialogue between the past and the present manifests. The old and the new come together and form a dynamic contrast that is both stimulating and inspiring. Old industrial elements are generally emphasized in the architecture of adaptive reuse: brick walls are left raw, columns and beams are exposed and concrete surfaces are left untouched. Traces of the past are not erased, but integrated into the design. Modern materials, like glass and metal, are often chosen for new building elements, like additional stair cases or additional floors. This choice of material emphasizes the confrontation of old and new even further. This dialogue is playful but also meaningful, as old buildings incorporate history. It is this contrast of the old and the new, the past and the present, that attracts people engaged in the cultural sector. It makes reutilized buildings the perfect fit for the cultural sector.

CREATIVE OFFICES: GOOGLE AND FACEBOOK

Reutilized industrial buildings are not only appealing to the cultural sector but also to the creative industry. Creative companies from all around the world show a clear preference for reutilized industrial spaces and set up their offices in old factories and warehouses. What draws these companies to such spaces? To answer this question one has to understand that the creative industry works in a very different way compared to traditional industries, because they create value solely by innovation. Software designers, architecture firms, marketing and advertising companies, media, and fashion design enterprises depend on creativity. Yet creativity is a very delicate resource: it is only found in certain people and is very difficult to manage. This is why creative companies do anything to attract talented people and to foster their creativity.

Facebook and Google are among the most creative companies in the world. Their headquarters are located in reused industrial spaces and are good examples for the design of the creative workplace. They do not have many similarities with the traditional workplace, in fact one might have trouble recognizing them as a workplace at all. If anything they resemble youth clubs. The interior of both headquarters is characterized by high ceilings and wide open spaces. As in many adaptive reuse projects, pipes and beams are exposed. Some walls are painted in bright colors, others are left bare. Employees use skateboards and bicycles to get around, or even slides. There are rooms for concentrated teamwork and areas where single employees can concentrate fully on their work. In many places furniture arrangements invite employees to gather and have informal meetings. The headquarters of Google and Facebook are certainly fun places to work at, but their design also follows a distinct purpose. Research has shown that the essence of creativity is playfulness, social interaction and communication. This is why the headquarters of Google and Facebook are designed in this unusual way: They are designed to stimulate creativity.
So why are creative companies drawn to reused industrial spaces? Probably for the same reasons the cultural sector is: old factories and warehouses offer suitable space and playful design. Converted industrial spaces might just be the places where the rare resource of creativity is supported best.

PART 2: THE RISE OF CREATIVE PARKS AND THE CREATIVE INDUSTRY IN SHANGHAI

THE FIRST PHASE OF ADAPTIVE REUSE

Creative people were drawn to old factories and warehouses also in Shanghai. The first adaptive reuse project in Shanghai was the conversion of an old warehouse at 1305 South Suzhou Creek Road. The Taiwanese architect Deng Kunyan discovered the warehouse in 1997. The art deco style building was built in 1933 and Deng Kunyan used it as his architecture studio after renovation. The renovation was unusual and remarkable, because Deng Kunyan focused on conserving the aged building. Old materials from demolition sites were used and the walls were painted with lime water to emphasize the age of the building instead of rejuvenating it. The result was a building with a remarkable atmosphere, past and present converged in this place, time itself paused, an almost melancholic comment on the quickly changing urban landscape outside. The renovation received an honorable mention for cultural heritage conservation by the UNESCO in 2004. Today the building is used as a youth hostel and was renovated some years ago; unfortunately the warehouse lost all of his qualities in the process.

The project was the first of what turned out to become the first phase of reutilized industrial buildings in Shanghai. By 2002, 30 old warehouses at the banks of Suzhou Creek were reused by over 100 art studios, galleries, design offices and workshops. This first phase could have become an early cluster for the creative industry in Shanghai, but the development was not supported by the municipality yet, and for the urban planning bureaus old buildings had no value back then. They were looked at as a burden, hence many of the industrial buildings that gave space to the early creative industries were demolished in order to make place for modern residential compounds.

M50, the now internationally know art district at Moganshan Road 50, was one of the early reused industrial parks. The project was as well for many years threatened by demolition. M50 is in many ways representative for the first phase of adaptive reuse in Shanghai. The reutilization happened step by step as more artists and gallery owners moved into the the former textile factory, situated at a peninsula of Suzhou Creek. The first tenant who moved here was the artist Xue Song in 1999, others followed soon. M50 was not developed by an investor and no architecture firm was commissioned with the reutilization concept, which is why the site has until today no unified design. The raw industrial feel of the art district is the result of this organic development. M50 is an outstanding example for adaptive reuse, a showcase for the power and the value of grassroots movements. Cities should foster such developments; they are rare phenomenons and can bring great fortune.

THE SECOND PHASE OF ADAPTIVE REUSE

The one project that would change the public opinion about the value of old buildings in Shanghai and well beyond was Xintiandi. The lifestyle park with a functional mix of restaurants, bars, hotels, galleries and shops was developed in 2002 by Shui On Land and designed by Ben Wood and Nikken Sekkei International. Xintiandi refurbished an old Shikumen neighborhood and displays an architecture that is a romanticization of the past. Xintiandi proofed to be highly successful and became one of Shanghai’s top tourist destinations.

In 2003, Bridge 8 would set a new standard for the adaptive reuse of industrial buildings in Shanghai. The project is located in the downtown district of Luwan, on the site of a former brake factory. The reutilization design was done by HMA architects. Bridge 8 features the typical fusion of old industrial elements next to new elements, like glass curtain walls, wooden decks and modern facade materials. Walkways and bridges were added in order to connect the buildings. In 2003 the architecture of Bridge 8 was pioneering and still holds up after more than a decade of operation.
But the truly pioneering achievement of Bridge 8 was the business model, which became a game changer for the real estate market in Shanghai. Bridge 8 was developed by an investor, the Lifestyle Centre, who leased the abandoned industrial buildings from the state owned enterprise who owns the site for 20 years. After this period the site will revert to the owner. While projects like M50 were renovated by individuals for their own usage, Bridge 8 was fully refurbished and modernized, the modernized office spaces were then rented to individual companies. The involvement of a developer who would finance the renovation of a site and manage the property after was a novelty. Bridge 8 obtains today the highest rental prices in the alternative office market. This business model proofed to be feasible and would be applied to countless abandoned industrial sites throughout the city. Bridge 8 is the first project of the second phase of adaptive reuse in Shanghai.

Between 2006 and 2010 creative parks mushroomed all over the city. This boom was caused by a convergence of several factors. A premise for the boom was the availability of vacant industrial buildings in the downtown area. Shanghai was an industrial city throughout the last century and transformed into a post-industrial city with global aspirations in the new century. Due to this transformation industrial production was forced out of the city and vacant industrial buildings remained. Many of them can be found until today in the middle of old neighborhoods. These factories are usually owned by state owned enterprises, who have to pay pensions. This is why they welcome the opportunity to lease these real estates. In some cases SOEs develop creative parks on their own. The supply of vacant factories was met by the need for office space. Shanghai has a high demand for interesting office spaces, the creative parks fill that need.

Eventually, the development of creative parks was supported by the municipal government. In May 2006, the Shanghai Municipal Commission of Economy released a paper, in which they presented a strategy for the development of the creative industry in Shanghai. The development of the creative industry was considered a milestone on the way to a more innovative economy, but China lacked innovative companies and creative talents. To overcome this shortage the paper suggested the development of creative parks, clusters where creative companies could find affordable space to open an office, and incubators, where creative talent could be bread. The paper also identified 36 creative parks that already existed in Shanghai, two thirds of which were adaptive reuse projects. M50, Deng Kunyan’s warehouse and Bridge 8 were on this list and became showcases for the development of creative offices. Government officials, developers and urban researchers visited these places to learn about this new urban typology. Adaptive reuse was good business and so new creative clusters sprouted everywhere in the city. Today there are hundreds of adaptive reuse projects in operation in Shanghai.

THE THIRD PHASE OF ADAPTIVE REUSE

The third phase of adaptive reuse in Shanghai is characterized by diversification. From the start adaptive reuse projects in Shanghai were multifunctional. The Loft on Jianguo Road for example is a traditional creative park, but also incorporates space for coffees, restaurants and bars. Many people come here during leisure hours, even though the project lacks design value, but the need for such places is high in certain areas of Shanghai. 800 Show on Changde Road is another example for a multi-functional creative park with places for culture and leisure. The highlight of the former electrical machine plant is the 120 meter long event hall, where exhibitions and fashion shows are held. The multi-functional program of many creative parks reflects the working culture of the creative industry, where work and life is often entwined.

A good example for the diversification of adaptive reuse projects in Shanghai is the development of Tianzifang. Tianzifang was founded back in 1998, when the famous painter Chen Yifei opened his studio in a former candy factory on Lane 210 at Taikang Road. The factory was located in the middle of an old Shikumen neighborhood, a traditional living quarter of Shanghai. Other artists followed soon and Tianzifang became a typical adaptive reuse project of the first phase, providing affordable space for creative people. The small lane on Taikang Road transformed however over the years. It became a showcase for creative parks during the second phase of adaptive reuse in Shanghai and attracted a lot of attention from government officials and researchers. Gradually small restaurants and shops opened, first along Lane 210, but eventually spreading into the adjoining Shikumen neighborhood. Finally there were more shops and restaurants than creative offices. Today Tianzifang is an art and entertainment district, a lifestyle park akin to Xintiandi, a place for creatives, nostalgics and tourists, an urban hot spot attracting thousands of visitors each weekend.

Surpass Court on Yongfu Road is another great example for the new trend in old building reutilization in the last years in Shanghai. Located in the buildings of a former aviation research institute in the former French Concession, the project was positioned as a lifestyle park with galleries, restaurants, and bars. The characteristic feature of the site is a fully enclosed courtyard, protected from the street. The courtyard offers place for outdoor seating and outdoor activities. Surpass Court opened in 2010 and was completely rented out on the first day. The project became an instant success, attracting many customers on evenings and weekends. The success of the project triggered new business in the immediate surroundings.

The transformation of Tianzifang and the success of Surpass Court reflects the need of the people in Shanghai for new urban spaces. Shanghai is a city in transformation and this means that the lifestyle and the needs of the population change as fast as the city does. Especially the young generation has a need for a new kind of places, places where they can go during their leisure time and on weekends, where they can meet friends, stroll around, express themselves, find new models of identity, and most important: watch other people. Such places are sometimes referred to as third places, places besides home ( which is the first place) and work (which is the second place). A number of reutilization projects became third places in the last years, like Tianzifang, or were developed as such from the start, like Surpass Court.

At this point we should take a step back and reflect on the development of adaptive reuse in Shanghai from a broader perspective. Why is there a sudden need for third places Shanghai? The need for new urban places is the result of the changing city dynamics. Shanghai used to be an industrial city, but transformed into a post-industrial city in the last decade. This means that the third industrial sector is now the dominating economic force in Shanghai. This has far-reaching consequences for the general dynamics of the city. Industrial cities depend on the availability of cheap labour, resources and the access to transportation systems. The rise of Shanghai as an industrial city in the last century was based on the location of the city at the mouth of the Yangtze River, which connected China’s mainland with the world. Post-industrial cities however depend on the availability of skilled human resources. We mentioned above that creative companies depend on the creativity of their employees. Shanghai has a great need for talent today, as the development of the creative industry in Shanghai has lead to a rising demand for creative people.

The ability of the city to attract creative talent is essential in this situation. Shanghai is now competing with global centers like Hong Kong, London, and New York for creative talents. The economic development of the city depends on its ability to attract creative people. In order to do so, Shanghai has to become an attractive city, a city where people want to live. The livability of a city becomes an crucial factor in an economy based on knowledge and innovation. There are many factors that make cities attractive, but the one we want to discuss here – because it is directly connected to the sustainability of reutilized industrial buildings – is urban culture.

Urban culture is in traditional urban theory tied to cultural buildings, like theaters, operas, museums, and so on. Many cities aiming to upgrade their cultural level built therefore such buildings. But this centralized understanding of culture is outdated and does not fulfill the requirements of a modern creative city. Urban culture is rather tied to creative people, engaging in the creation of culture, and places where these creative people can engage in urban culture. Urban culture today is less linked to cultural events as to lifestyle. This means cities that have a rich urban culture, will be able to attract even more creative people; while cities without a vital urban culture, and will struggle to attract creative people in the first place. Cities like New York, Berlin, or London, which already are bustling cultural centers, attract creative people much easier, because they allow them to live the lifestyle they want to have. This is why these creative cities have the most agile creative economies.

The significance of Shanghai’s creative parks becomes evident at this point. Shanghai can clearly not compete with cities like London or New York in terms of urban culture at this point in time. Shanghai is in this regard still a developing city. The creative parks are a tool to boost this development. They are the infrastructure that is required for the development of a creative class and a lively urban culture. They are the centers, where creative people can meet and can engage in the creation of culture. They are the incubators for the emerging urban culture of Shanghai. The typical combination of workplace and third places is in this regard highly effective, as it allows creative talents to engage into an overall creative lifestyle. The architecture of adaptive reuse also helps in the development of an urban culture, as this style is attractive to creative talents.

ECONOMIC VALUE OF ADAPTIVE REUSE

The short history of adaptive reuse in Shanghai has proven that the conversion of old industrial buildings is profitable. Adaptive reuse is good business. From the start adaptive reuse in Shanghai has answered the need of creative companies for extraordinary offices. It is actually fascinating to see how the creative parks reflect the economic development of Shanghai in the past decades, the great transformation from an industrial into a post-industrial city. Originally places for industrial production creative parks are now places for innovation.

ENVIRONMENTAL VALUE OF ADAPTIVE REUSE

Adaptive reuse projects are not only good business; they are also beneficial for the environment. A factor that becomes more important as the environmental situation in China becomes more critical. Pollution might be the single biggest threat to the future development of China. Building construction sites are one of the major sources of pollution, which is why the building industry is responsible to take action. Waste from construction sites is currently accountable for 30 to 40 percent of all the waste from urban areas. The cause for this high amount is not only the growth of cities but also the short lifespan of buildings. The average building in China lasts only 30 years, compared to 74 years in the United States and 132 years in the United Kingdom. Building demolition is one of the main sources of urban waste. The goal must be to increase the lifespan of buildings. Reutilization is therefore an important strategy on the path to a more sustainable urban environment. Increasing the building lifespan would also reduce greenhouse gas emissions. Greenhouse gases are produced during the production of building materials and are embodied in the building structure, which is composed mainly of concrete. Improving the quality of concrete production is one way of approaching this source of greenhouse gases, prolonging the lifespan of buildings is another way.

SOCIAL BENEFITS

Many social benefits have been discussed in this article; we want to highlight only a few: The reutilization of old buildings is a way of preserving the substance of the history, which is incorporated in these structures. This quality of adaptive reuse is especially important in China, where the rapid process of urbanization leads to the destruction of many old buildings. Old buildings do however play an important role in the urban environment; they connect the city to the past and give people orientation in time. Another important contribution of adaptive reuse is the architectural diversity. Adaptive reuse projects are often special, offering an architecture that is different from contemporary building norms. Adaptive reuse eases therefore one of the big challenges of the new cities of China: the monotony of the built environment. People need places they can relate too, but the monotony of the new cities makes it difficult for people to connect to their urban environment. Adaptive reuse can be looked at as place making, and many projects in Shanghai show the potential of adaptive reuse for the creation of extraordinary places. Most of all adaptive reuse projects have the potential to become inspiring places, places that trigger innovation and nurture creativity. Innovation will be the most important resource of the future, because the cities of tomorrow will have to rely more than anything on the creativity of their people in order to endure./span>
