Why China?

Project Goals, Description & Argument

Problem The proposal outlined in this document has been developed to address the rapid urbanization in developing countries such as China. As continental Asia is urbanizing at a rate of over 150,000 people per day, growth which is projected to sustain itself over the next 20 years1, it suggests that quality architecture is and will be in high demand to meet the needs of urban dwellers. China has reached a 50% urbanization rate,2 meaning that over 700 million people now live in Chinese cities. In terms of economy in the global recession, 18 of the world’s top 40 fastest growing cities (of the world’s largest 200) were in continental Asia3. The combination of consistent economic growth and influx of people moving to take advantage of opportunity in urban areas has created a real estate boom which is unprecedented. These trends seem to suggest that keeping up with the increasing demand for buildings to serve the burgeoning urban population will be difficult for architects utilizing a traditional design and construction process which can take years to complete one large-scale building. Allowances for creativity, site-consciousness and user experience are left by the wayside in the speed of production in current developments. The result is massive development of “cookiecutter” buildings which lack standards of quality and rarely address contextual or environmental issues.

general consideration for design and quality, and some even ignore basic needs such as access to amenities and transportation. With roughly 64 million unoccupied homes in China (the majority of them new construction),4 speculative building is a commonplace activity. In addition, quality continues to be an issue with the rapid building in China, even to the point of causing deaths as in the Sichuan earthquake of 2008 which involved over 68,000 casualties. Shoddy construction contributed to many of the deaths, and brought the lack of quality control in Chinese construction to the forefront5. Even without natural disasters, methods are unreliable, causing accidents such as the 13-story residential tower that toppled over in its entirety when excavations were not properly completed and the pilings failed6. Finally, worker safety has recently become a highlighted issue in the news.7 Frequently, stories reach the US of dozens of Chinese workers being killed in manufacturing- and construction-related accidents, many of which could be prevented with better standards.

To mediate the demand for buildings while responding to these issues, this project proposes a prefabrication methodology to create quality, thoughtful, and sensitive architecture that is completed in a timely fashion and within a reasonable budget. Prefabrication typically reduces construction time and costs while allowing for quality control.8 By creating a framework for a prefabricated high-rise, the system can be replicable across varying geographic areas and in different contexts, thereby filling the need for new buildings in the developing areas of China that also address specificity. Creating thoughtful development that meets the current and future needs of China’s expanding metropolises will be a challenge, and this project is aimed at providing one solution. By leveraging known processes, current methods could be improved. 4­  Donald, Alastair. “Ghost Towns.” Architectural Review. September. (2012): 32-34. Print. 5­  “Sichuan Earthquake.” New York Times.

Why Prefab? Methodological Case Studies

Traditionally, especially in the US, prefab has been applied to mostly residential projects and has recently seen a resurgence with goals for sustainability. Applications of prefab were explored more extensively in the mid-20th century, but were eventually abandoned for more traditional techniques. Today, as construction costs continue to rise, many owners/clients/developers are looking for ways to save money and increase efficiencies, leading some to prefabrication.

In a study of typical versus manufactured single-family homes, there was

a 32% cost savings.

Among professionals who promote prefab, there are many advantages: lower labor costs in factory settings; increased quality control; less material waste; fewer weather-related delays; increased job safety for workers; less site disruption; and the ability to complete site work and building component work concurrently1. Additionally, if a prefab framework is developed and can be leveraged for a large complex or future projects, the cost savings could be substantial. The case studies presented in this section look at the different ways that prefab has been practiced in several applications. From the scale of the single-family home to a high-rise office building, the methodologies utilized have been varied and each have their own strengths and weaknesses.

Cohen Brothers Developments



Location: Colorado, USA Architect: Braun Yoshida Developer: Cohen Brothers Completion: Ongoing Area: Variable

Beginning during the housing boom of the early 2000’s, the Cohen Brothers developed a framework called the Whole House Building System, a patented process in which an entire single-family home is fabricated in a factory setting and trucked to its final site. Once a site is selected for the neighborhood development, a prefabricated warehouse structure is erected nearby in which the houses are then built. Using special trucks and platforms, the houses are then loaded and transported (less than half a mile, typically) to their site where foundations were previously laid, and bolted down and sealed. The company claims it can reduce construction time by up to 75%, costs by 20%, all while reducing errors and defects1. Once construction of the housing development is complete, the prefab factory is disassembled and taken away.

Atlantic Yards B2 Tower



The Atlantic Yards project has been in planning since 2003, but because of controversy over the site, issues with architects and the community as well as the economy, has been delayed for some time. The arena component recently opened this year, and the modular residential components are set to break ground before the end of 2012.

Forect City Ratner has been the impetus behind developing a modular system to build the 16-building residential complex. With over 6,400 residential units, Bruce Ratner (CEO of FCR) wanted to find a more efficient way to complete the complex1. The first building, B2, which is currently being designed and is set to break ground in November, has vetted the modular system mainly through the use of BIM. The structural design of the building calls for a steel braced-frame superstructure at the core, which provides lateral support. Each of the more than 900 modular units is then built off-site (at the Brooklyn Navy Yard, 1.5 miles from the site) and has its own steelframed chassis. The modules are not totally standardized, but are 10’ tall and 15’ wide, ranging in lengths up to 45’. Once on site, these modules will be stacked, clipped into the superstructure, and then connected at the perimeter to form a structural diaphragm providing additional stability2.

Habitat 67


~ Habitat 67 was initially inspired by Moshe Safdie’s thesis work at McGill University and was eventually realized for the 1967 World Exhibition in Montreal. Using prefabricated concrete modules was somewhat revolutionary for the time, but has since stood the test of time in its construction.

Detail view of the Habitat modules. Credit: Sylvain Pastor.

The concept behind the housing complex was to create units which had their own sense of privacy and outdoor space while accommodating different needs. The units range from one to four bedrooms, with terraces of varying sizes. The entire complex was designed to be a dense, urban, self-sustaining and yet pleasant environment. The structure of the complex is created with a single unitized module of precast, posttensioned concrete. Each module is 10’ tall, 17.5’ wide and 38.5’ long. These modules are stacked to create the unique and distinctive pyramid form with voids and terraces1. The 12-story structure is self-supporting within these modules and also relies on its form for stability. Apartments within the complex are created with varying combinations of the standard modules.

Hong Kong and Shanghai Bank




The Hong Kong Shanghai Bank building was approached by Foster + Partners with the impending return of the territory to China’s possession in mind, in addition to the needs of the banking owner. The timeline for the project was tight, and the client wanted flexible spaces that could change with the needs of the company. In response to these needs, the architect developed a design-build framework within which over 100 subcontractors worked with the designers to imagine and create a totally prefabricated building1. The whole building was designed to be disassembled and moved to a new location should any political unrest cause issue with the site of the bank. In addition, the modularity of each component allowed the company to reconfigure all the internal spaces to meet the changing needs of the users.

The main structural framework allowed for sections of 5-7 floors to be suspended from a Vierendeel truss superstructure. These large structural components allowed the floor modules to go up quickly, and have also created an iconic expression on the exterior of the building. All the components of the building within the structure were modularized and fabricated offsite as well, down to the lighting, flooring, and partition wall systems. While each component of the building was essentially a new product which had to be mocked up, tested, and refined, the effort paid off in the end with a faster construction time and a flexible building which has served the client over the past 25 years2.

Lloyd’s Building

~~ ~ As a historic institution of London, Lloyd’s has taken residence in four buildings since the 17th century when it was founded, with the Rogers building on Lime Street being the most recent. When approached with the project in the late 1970’s, Lloyd’s had occupied a building adjacent to the new project site for nearly 20 years and were experiencing growing pains1. The main issue with the redevelopment of the site was in providing working spaces through the entire renovation and construction project, and creating spaces that were flexible enough to grow as the company did.

Overall view. Credit: Architectural Record via Richard Rogers.

In developing the process for the building, Rogers was interested in prefabrication as a means to define static versus changeable spaces2. The main concrete superstructure was prefabricated, while the floor infill was site cast. Bathroom pods were entirely fabricated off-site and were trucked in at night and placed into the structure to reduce site storage. In addition, an innovative services network was developed with underfloor systems and compound ceiling panel systems working in tandem, relying on mostly offsite manufactured components3. The structure has allowed open and largely column-less spaces in the building that have facilitated the company’s varying uses over time. The ‘served’ and ‘servant’ spaces were originally conceived over 30 years ago, but have been able to withstand the advancement of technology.

Nakagin Capsule Tower

~~ ~ Sited on a small plot of land in densely-built Tokyo, the Nakagin Capsule Tower was designed to utilize a hybrid tradition and prefab construction system to ease the construction process. As a member of the Metabolist Movement in Japan, Kurokawa was a proponent of collaboration between different disciplines, and emphasized flexible, interchangeable designs. The design process resulted in a tower with prefabricated pods that could be added and taken away.

Case Studies

Geared towards businessmen, the size and amenities of the living spaces within the tower are very minimal, and were totally manufactured in a factory setting. The structural framework for the building was based upon two steel-concrete composite cores that were erected on site in a relatively typical fashion. Each of the 140 capsules were made off-site and then transported to the building and clipped into the superstructure of the 11 and 13 story cores. This prevented conflicts on-site during construction, as most of the fabrication was done in the factory setting. However, the production facility was over 450 kilometers (280 miles) away, increasing the cost and complexity of the project due to transportation. Each unit is 4 by 2.5 meters (13’ x 8.2’)1. Though the architect originally intended for the capsules to be removable and replaceable, the building has fallen into disrepair and is under threat of demolition. Since the global recession of the last several years, nothing has been done yet to improve ro raze the building. Kurokawa hopes to replace the old capsules with updated ones, but will rely on financing to complete the work.

Sky City Tower



Causing ripples in the global news pond, Broad Sustainable Building (originally an air conditioner manufacturer) announced in mid-2012 that they would build the world’s tallest prefab building. They also noted that it would become the world’s tallest building at 838 meters, 10 meters taller than the Burj Khalifa, and they would complete it in less than half a year. Situated in rural Hunan Province, the head of BSB Zhang Junjie, decided to get into the construction business after the devastation of the Sichuan earthquake in 2008. Spending several years on developing a framework for prefab high-rise buildings, the company completed its first 30-story hotel in just 15 days, a fact that went viral over the internet with their time-lapse video of the project site. Applying the same principles, the company believes it can complete a much larger scale building. Combining the design, manufacturing, and assembly process under one umbrella, BSB has essentially streamlined the process for creating a building. Factories that fabricate all the necessary components of the buildings are within close proximity to the building site, transportation of components has been optimized and assembly of the building parts on-site has been improved. The whole process works much like a large, extended assembly line.

The structure of the system is essentially boiled down to interlocking floor panels and columns, which have been tested for earthquake stability. All components are uniform and unitized for efficiency and ease of transportation.

Why High-rise? Architectural Case Studies

While still arguable, many architecture professionals believe that higher-density development is more sustainable. In Asia and China, many developers are proposing mixed-use, high-density tall buildings to meet their own requirements for rate of return and tenant occupancy, while also providing a sustainable lifestyle for its users with access to necessary amenities, transportation and quality living and working spaces.

In China alone, 45 buildings over 150 meters were completed in 2011,1 with 107 completed in Asia as a whole. Twelve of the worldâ&#x20AC;&#x2122;s top 20 tallest buildings in the world in 2020 will be in China, as projected by the Council on Tall Buildings and Urban Habitat. Tall buildings serve the living and working needs of a growing urban population, and density encourages sharing of resources. In looking to develop a high-rise design for growing urban areas in China to serve the people moving into cities, projects have been studied here for their spatial components as integrated within a mixed-use building, along with their architectural strategies.

While the district has one of the higher GDP per capita in the country and has a wealth of mineral resources, the radical plan to build an entirely new city for 1 million new inhabitants has resulted in a virtual ghost town. Originally planned to be 137 square miles, the failing status of the current 14 square mile swatch has essentially halted progress. While high-quality amenities such as museums, hotels, and restaurants have been planned and built along with the many residences to accomodate the hypothetical inhabitants, less than 30,000 people live in an area which could easily serve 300,000.1

The form of the building responds to the scale of the site with setbacks and perforations for skygardens. Natural lighting and ventilation were given priority in the design, as well as easy access to outdoor spaces. Skygardens, skypavillions, and even green walls have been installed to ensure access from both public and private areas. Materials were chosen for their relation to the cultural standards of the area and their ability to prevent solar heat gain and allow breathability.

With six of the world’s top 10 fastest growing cities in the world, China has established itself as a premiere place for expansion.1 In looking for the most active areas where architectural development would be useful, a variety of criteria were considered to narrow down the field of opportunities. Four cities were chosen for their array of qualities, each providing a unique situation with differing conditions to be addressed in the design process. The criteria that were used to evaluate and narrow down the options in China were the following :

• High rates of urbanization • Variety in climate • Variety in economic status (GDP) • Variety in density • Externally recognized for growth Utilizing resources such as the China National Bureau of Statistics Census data and UN Habitat survey as well as Google Earth, site were chosen for their representative qualities of the varying regions and typologies in China.

Foshan is located in the Pearl River Delta zone in the greater Guangzhou region. Located in close proximity to other large urban areas as well as the coast, its economy has been fueled by international investment and industry. Traditionally known for its porcelain industry, it has now become a major center for manufacturing of all types of goods. It also has several Agricultural Model Districts which serve to modernize agricultural practices, and so has became a major food source. It is also known for having a large immigrant population. Foshan had the 14th highest GDP per capita in China in 2010, and continues to show economic and physical growth. With a humid subtropical climate, the area has hot, humid summers and cool, mild winters with most precipitation occurring during the summer months. Prevailing winds come from the northeast and south. Current residential sales in Foshan have been slow in 2012, which has been mostly blamed on restrictions by the government limiting supply and access. Demand is expected to increase.

Shenyang boasts the remains of a 7,200 year old neolithic village which is a tourist draw. As the largest city in northeastern China and the 11th largest in the country overall, it is a more stable growth city. The eastern part of the city leads to mountain foothills while the wester portion is a flat plain running into the Liao River. With a humid continental climate, it is similar to many other major coastal cities in China with the exception that it is influenced by the Siberian anicyclone weather in winter. Shenyang is primarily a heavy industrial center, which is how it began its growth initially in the early 20th century, but is also a large agricultural center and high-tech producer. More recently, auto and software manufacturing has prevailed. Shenyang is known for being a multi-ethnic center, with various minority groups and expatriates. Demand for high-end real estate in Shenyang has remained relatively stable in the past year, while demand for rental properties has increased.

Making Prefab Parameters & Strategies


The Chinese goverment plans on building 20 new cities a year

for the next 20 years.

Looking at the type of people currently living in cities and those moving in who have the highest need for buildings, many of them are itinerant workers, along with people looking to invest in real estate. Each area that could possibly be developed with this framework has its own demographic distribution of people with differing needs, so a survey of possible housing types has been established here for a variety of users, in addition to considering general stakeholders for the project as a whole. Government. The Peopleâ&#x20AC;&#x2122;s Republic of China has been and will almost certainly continue to drive expansion and development across the country, and will therefore play a role in the development and deployment of this framework. Working with them to ensure code compliance and deployment strategy will be key in the success of the project. Owner & Developer. As the scale of the use of this framework could become quite extensive, it is likely that a large investor or developer would be beneficial for its development and success. Though a higher up-front investment would be required in the development phase, a higher return on investment would follow as the system is replicated over time.

Users. A wide variety of people with differing needs are coming into Chinaâ&#x20AC;&#x2122;s cities, so this array has been outlined to better understand the impact on the project. While the types of users present at any given site will vary, getting a basic understanding of each will directly impact the decisions made in the design of the framework. Parameters & Strategiesâ&#x20AC;&#x192;41

Within 2 years of occupancy,

over 70%

of the Hong Kong Shanghai Bank Building had been internally reorganized.

Permanent Condominium Owners

Many long-term residents of growing cities are looking to invest in real estate as the property bubble continues in most of China, so creating opportunities for this group will support the development as a whole. These users will need stability, will likely be given priority to views where available, and have access to private amenities.

Consistent Apartment Renters

Semi- or mostly-permanent city residents who are not yet able or interested in purchasing property will be looking for rental units. These units should be well-equipped to deal with a variety of family sizes and be built to withstand a lot of use.


As people move into cities, starting a business or continuing one is a means of support. Providing spaces in which new residents can live but also support themselves will increase the sustainability of the development and surrounding urban area. These spaces will need to be the most flexible to accomodate a variety of uses.

Temporary Renters

While many people are permanently moving to the city, hundreds of thousands of migrant and itinerant workers move into the cities seasonally, usually for 6-12 months. While some may choose to stay, providing temporary residency opportunities would be beneficial.

Business Owners

Condominium Owners

Each building should provide basic retail/business spaces on lower levels to create opportunities for residents and neighbors. These spaces will need to be as flexible as possible to meet the needs of changing tenants over time.

Program Residential. Given that the focus of this project is accommodating the growing influx of people into Chinese cities, the foremost goal of the program must be to provide a variety of living spaces for these people. In addition, looking at China’s 100 tallest buildings, only 15% of them offer a residential component.1 Providing a variety of flexible living spaces which can accommodate different needs will be important, and will inform the structural and architectural design of the framework. Basic Needs. In addition to this basic need, research on China has shown that the increasing urban population has put unforeseen stress on typical infrastructure such as health care and educational facilities, so providing basic program to supplement these needs would be best as well.2 Public Amenities. Lastly, one or more retail components as well as common areas may be needed depending on the available surrounding resources. Each site that the framework may be deployed in will have different needs, and therefore the program will have to respond accordingly. The proportions of each established type of program may vary as a response to the existing amenities, residential opportunities, and population.

Only two

Metabolist buildings were constructed: Safdie’s Habitat 67 and Kurokawa’s Capsule Tower.

Design Flexibility & Use. Looking back in history to the Metabolist movement of post-war Japan, similar goals were present in terms of creating buildings to serve a demand for housing that had an architectural response as well as a consideration for efficiency and feasibility. A similar approach to the design and implementation processes should be taken with this project, in terms of team integration and collaboration, as well as creating a framework that is flexible over its life span.

Clusters in the Air, Arata Isozaki. 1962.

Aesthetics. The architecture that is currently being constructed in China seems to be consistent in its lack of attention to aesthetics. By utilizing the structural framework in conjunction with an architectural approach, the buildings created with this framework will have a unique and distinctive aesthetic, standing out from their peers. Sustainability & Experience. In looking at Safdie’s motivations behind the design for Habitat 67, creating an outdoor space for each residential unit was of particular importance. As more people move into cities and sacrifice direct contact with nature, creating access to outdoor or green spaces as well as natural light and air will be key for promoting the experience of living in tall buildings. In addition, passive strategies can be leveraged when outdoor or green spaces are incorporated into buildings, improving overall performance. Many people moving into cities may not be as economically stable as more established residents, and therefore not have access to the same amenities. Creating pleasant open and green spaces in the building will hopefully improve the experience within the building, as well as impact the exterior perception of it from a non-resident’s point of view.


Parameters & Strategies

Community. In rural Chinese towns and villages, communal living is a key part of life. Within larger cities and residential living, people continue to form their own types of communities, in addition to or in spite of the architecture. Multi-generational living is also common, combining members of the same family that are a variety of age groups. A common, but quickly diminishing typology of lowdensity living is the hutong, which forms and architectural and spatial community. While many Americans live with vast amounts of space (on average 800sf/ person1), the Chinese are typically more likely to live in much smaller areas, averaging less than 100sf/person2, in both rural and urban settings.

The architecture of the framework, while being flexible, should allow for opportunities to create shared spaces within the building to facilitate and promote the growth of a community within it. To accomplish this, the module for the building will be developed to allow for larger volumes to open up within the building structure. Openness and natural light will be key to promoting communal aspects of the building, and the outdoor and green spaces will be leveraged for this purpose as well. Structure & Architecture. The structural and architectural systems of the framework will need to work together to create 1  Dietz, Robert, and Natalia Siniavskaia. “The Geography of Home Size and Occupancy.” Housing Economics.

a cohesive whole. Structurally, a kit-of-parts will be devised which adhere to the requirements for transportation, but allow more than one prescribed choice to create variety within the architectural expression of the buildings created. While relying heavily on structure for its articulation, the architecture of the building will also be defined by the palette of available materials and exterior options for the buildings, which will be driven by site context and climate. Safety. Aside from safety considerations during the fabrication and construction processes which will be addressed, the safety of building inhabitants is key as well. Most of China lies within seismic zones, and in the past has had negative experiences with lack of properly designed architecture and earthquakes. The inherent stability of the framework must be tested and vetted to ensure its performance during seismic events. In addition, more than adequate egress must be provided.

Tertiary Building Performance Impact of Materials Access to Exterior Spaces Transparency of Ground Level


Parameters & Strategies

Looking at the strategies in several of the case studies considered here, such as the Hong Kong and Shanghai Bank, pushing primary vertical circulation to the exterior of the building could be an alternative to typical centralized circulation that also provides additional structural stability.

90% of all Implementation Team. Initially, an integrated team should be formed comprising architects, engineers, and constructors to vet and complete the framework so that it may be implemented on a large scale. Once the system has been fully vetted, an architect may take on the task of building individual buildings by 20’ Container utilizing the framework to its full 20’ L x 8’W x 8’6”T 6m x 2.4m x 2.6m advantage. Fabrication. In fast-growing cities with high demand for new buildings, it would be ideal to construct a fabrication facility in close proximity to that area for easy transportation of prefabricated components. The initial cost of the facility will be offset by the savings of extensive design fees for individual buildings, as well as reduced waste in both materials and time. Areas with less intense demand and/or proximity to industry may leverage the opportunity to work with an existing manufacturer to lease their facilities for production. A kit-of-parts system will be devised so that mass production of the system can be streamlined over time. Depending on transport, the overall building cost for each iteration of the framework will decrease over time due to repeated processes, but will also allow for innovation and improvement.

Transportation. Ideally, production would be as close to potential sites as possible to reduce costs due to transportation. Road transportation costs vary, but are around US$0.06 per tonne/km, meaning it costs six cents to carry one tonne for one kilometer. Therefore, the feasibility of the framework will decrease the farther than prefabricated components must travel to the building site. Some projects may have the ability to foot a larger transport budget, but limiting the location of fabrication to less than 100km away from the primary target locations seems reasonable to reduce overall costs. Assembly. Depending on site conditions, components will be brought to the site for assembly as required while optimizing for transportation loads, reducing area needed for material storage and component assembly. Site-built aspects of the framework will also be partially prefabricated (where possible) to reduce site demand and speed up on-site construction time.

Parameters & Strategies

Prefab Execution Next Steps

To move forward with this framework, the following steps will be addressed to being the design process: • Create an architectural approach for each individual site based on climate and culture. • Establish the primary and secondary structural system strategies, materials, and fabrication methods based on the common needs of all sites • Establish general program and spatial requirements for each site framework. • Determine exterior envelope needs and strategies for each site. • Determine how the kit-of-parts framework will be broken up and fabricated in terms of systems, envelope, fixtures, and finishes.

FCR estimates they can reduce construction costs

by over 20% with prefabrication, a figure which will likely increase as it is replicated.

Once the needs of each site have been addressed, a ‘universal’ system will be developed. While this framework will be created to address the needs of varying geographic, demographic, and climatic conditions across China, the framework will likely need to change over time and across new areas. However, once initial structural and architectural processes have been developed, they can be replicated, saving time and money.
