The strategy by FangCheng Architects for the affordable housing design in Shenzhen involves bringing the apartments outside the urban core. Their concept is to build as many affordable houses as possible in the urban center, which can decrease residents’ travelling time and increase usage and sharing of urban facilities. This strategy aims to improve social housing integration in the urban core which is done through building 6200 affordable housing units in the urban center. More images and architects’ description after the break.
The master plan for the 12th Five-Year-Plan for affordable housing in Shenzhen SEZ, CN Shenzhen government plans to raise funds to build 240.000 affordable housing units with an 15.36 million square meters construction area. However, in the current strategy, most of the affordable housing is planned to be built outside the urban center, and many are even in the urban fringe. In this case, due to travelling time, cost and sense of isolation from the urban center, residents adopt a negative attitude to the policy even though the housing price is low.
The total building area for affordable housing in Shenzhen in the 12th Five-Year-Plan consists of the entire landmass of Shenzhen bring 1953 sq. kilometers. This includes a 395.81 sq. kilometers special economic zone (SEZ). After thirty years of development, the utilization of land becomes more and more intensified, so how do we manage to build 15.36 million sq. meters for affordable housing under the land-contraction policy? And how to bring practical benefits to low-income groups who persistently make contributions to the city?
The built area distribution map represents which manner this goal can be achieved Through analyzing the built distribution map what becomes obvious is that 20% is occupied by municipal roads. These municipal roads are wide with a beautiful artificial landscape along the sides which lend for future development and construction of urban space.
According to the road wisth analysis, there are several primary distributor roads, such as Shennan, Beihuan and Binhai road, whom are wider than 50 meters, and wider than 100 meters including the greenbelts on either side. To some extent these roads increase efficiency, but from the sustainable utilization of land view, they divide the city into pieces with a single function. This causes the city to loose its comfortable human scale.
The city is divided into various regions that operate like isolated islands due to the increasing traffic flow on highways. Therefore, the city lacks a pedestrian system, which is currently not sustainable. We need to promote pedestrian and public traffic in order to enhance the connectivity to each region, the question will be: Is it possible to use affordable housing as a means to reach this goal and modify the city?
The design proposal for affordable housing comes forth out of the city function typology study, which asked for several prototypes for a building. Our design of a “bridge building” encourages low-income habitants to live inside the urban-center and rebuilds the pedestrian traffic system for the whole city.
The proposal is neither the 10 thousand residents community nor the low-cost rental housing, but a city wide network which can increase the utilization of facilities, enhance the pedestrian system and provide a chance for residents to decrease travelling time to work. According to the land-use analysis, road-width, function distribution, urban density and height of the buildings running along the main traffic arteries we have come to 4 types of “bridge buildings”: single bridge, mega bridge, platform bridge and cascading bridge.
This typology of the single bridge can be built in an area that needs flow separation, in this case Beihuan road is selected as testing site, and provides an opportunity to replace the pedestrian bridges that are situated every 200 meters. The first floor holds free rental space for peddlers which sell life necessities. Inside the building, there is a wide staircase linking the upper residential floors, which on it self are again connected through several atria which serve as semi-public space. As a whole this typology works like a micro-city.
Along densely built, the mega bridge on Shennan road is located between the vast number of high-rise buildings. The area brings about a large group of workers, mega bridge unites this area by creating a single platform which link not only all the shared public facilities but also transportation, metro and bus, and weaves seamlessly into the existing structure and poses a mixed and differentiated architecture. The bridge will hold a diverse program including bookstore, cafe, restaurant, in order to attract, blend in and become a platform where people can enjoy a panoramic view of the urban landscape and become the living room of the city.
During rush hour, between the modern high-rise of Chegongmiao and Xiasha Urban village along Binhai road, the current footbridge cannot satisfy the intensity of urban flow, therefore the platform bridge is placed in-between, as to provide a multiple linking connection. To prevent hinder to car traffic because of shade the bridge is punctured on key locations, this will at the same time make for an interesting view from the platform. Low income habitants can utilize the open space of the platform and share facilities with the densely populated urban village. Since housing prices will be low they will form a direct competition with the village and cause prices to drop.
The cascading bridge overlooks the Shenzhen coast along Binhai road and allows for amazing panoramic views, at the same time it makes for an easy access to the mangrove from the north and dismisses the need for parking. The bridge provides expect a view, a vast variety of outdoor activities like a basketball and tennis court, swimming pool and restaurant.
The residents can choose according to his/her needs and conditions a unit composed of the standard module of 3*3*6m. Each bridge holds each kind combination of units to increase the diversity of habitants.
To inform the future residents of the possibilities, software is created that can run on windows, mac and android. By filling in a form the app sees if you are eligible for an apartment, what kind of unit you can choose from, the level of the rent and which bridge is closer to your job. Our goal with this system is to make society aware of the possibilities, and encourage them to explore.
