POA Architects released the design of ‘Ou Haiwan public Rental Housing(Nanhu Ouhai Home)’.
Ouhai Bay Public Rental Housing (Nanhu Ouhai Home) is located at Xiafang Road, Ouhai District, Wenzhou, Zhejiang Province, close to Xiafang Road Station of Metro Line S3, and looking towards the Sanyang Wetland. The planning unit is 97 hectares and the implementation unit is 25 hectares, with a total construction area of about 720,000 square metres, consisting of three residential plots and one public building support plot. The project was launched in 2020 and is one of the first pilot projects for future communities in Zhejiang Province.
As early as 2018, POA Architects began a study of social housing, researching the historical development and characteristics of social housing in various countries under the theme of ‘Sociality of Social Housing’. During a visit to Singapore, POA initiated a discussion on this topic with a local university, encouraging young students to imagine ideal housing.
In 2020, Wenzhou Ouhai Urban Construction Centre invited POA to design Ouhai Bay public housing. As the first comprehensive social housing project, POA hopes to break through the conventions in concrete practice and promote the development of social housing in China with innovation, so that people can reach self-realisation in the community. The large community accommodates the city and the lives of its residents, awakens the social nature of housing, and solves a series of specific problems about housing in the current rapid development of Chinese cities.
open neighbourhood
Opening up the community walls and introducing urban roads. Each residential plot is divided into a number of residential units. The first floor is elevated or used as community support facilities, introducing a series of rich functions such as community supporting commerce, community health stations, childcare points, shared restaurants, 24H bookstores, gyms, and home care, etc. Community life is integrated into the city, and the urban scale is more pleasant.
three-dimensional community
After returning the first floor to the city, the POA leaves the first floor for internal use by the residents of the community, forming a series of three-dimensional green roof spaces, and a stormwater corridor that re-envelops all the residential units into a whole, turning it into a huge park that links up a variety of resident-oriented community functions such as a neighbourhood centre, a university for the elderly, a cultural service centre, a commercial support facility, and rooftop gardens.
floating garden
In addition to the floating park on the first floor, POA has left different scales of landscapes on the first floor, rooftop garden, semi-outdoor grey space and balconies, and has also ensured that the greening rate reaches 50% in the design of the guaranteed high-density residential units in the city centre, so that those who reside here can enjoy a more comfortable life and be closer to nature.
the right in the sun
Under the premise of higher plot ratio and smaller house sizes, we strive for as many south-facing rooms as possible, and the design adopts a large-width and short-depth house type, with the corridors set in the north to ensure that each family has sufficient sunlight conditions.
Kasumi & Place
Relying on the architectural space, the concept of ‘Xia&Square’ is evolved. The shared space is like a spreading cloud connecting 12 residential neighbourhoods, and the buildings are no longer isolated from each other, but are enclosed or semi-enclosed courtyard spaces, with pleasant scales bringing a sense of intimacy and belonging to the space, and the ecological modelling design of the building enriches the fifth façade of the city. the fifth façade of the city.
Household Design
Ouhai Bay public rental housing has three main types: 40 square feet, 90 square feet and 110 square feet, the differentiated configuration of the area segments, echoing the theme of ‘innovation and entrepreneurship’ in the community, and taking into consideration of the family structure of ‘single youth, married youth, two generations under the same roof’ in various aspects, the whole life cycle design allows people of different age groups and family structures in the community to have suitable house types to really find belonging and comfort and ease of mind. The whole life cycle of the house type design, so that the community of different age groups and family structure of the people can have a suitable house type, really find a sense of belonging and comfort.
Industrialisation & Low Carbon Buildings
The Ouhai Bay public housing project has achieved more than 50 per cent industrialised production, with structural units and interior partitions of the building adopting assembly design, all prefabricated in factories, which is highly efficient and environmentally friendly. Residential modules are prefabricated in the factory and can be installed directly after being transported to the project site, which reduces the difficulty of construction work and drastically reduces pollution. Assembly construction can reduce the cost and improve the quality of residential construction.
Focusing on green and energy-saving scenarios, through the use of active and passive design techniques, making full use of natural resources, natural ventilation, natural lighting, while taking into account the building's surrounding environment and vegetation, controlling the building's orientation and form, and paying attention to environmental climate change, etc., the healthy and sustainable architectural design will make the community a ‘better city life’ basic unit, so that people and nature can live in harmony. The healthy and sustainable architectural design will make this community a basic unit of ‘Better City Life’, and allow man and nature to coexist in harmony.
The design of the Ouhai Bay public housing project triggered POA to think more deeply about the housing problem in China. Pan Chengshou said in the lecture ‘Future Community’: the city ultimately belongs to the people here, whether it is a residential area or a large public building in the city, the success of the project finally comes down to the care of people.
Modern residential planning in China began in the planned economy period after the founding of New China. Receiving the double influence of Western modern architecture and traditional Chinese architecture, the conservative and closed ‘deep house compound’ became the basic form of urban living in China, and the pattern of the compound continues to this day. After the reform and opening up, the process of commercialisation of housing has advanced, and housing has become a mass-produced custom-made product.
People should be at the centre of the living space. Dwelling is not only about the dignity of life and social justice, but also about the self-realisation of human values. Ou Haiwan public housing project puts forward the concept of integrating subsidised housing into the community and sharing urban life, creating space through three-dimensional community and composite use of land, while maximising green space and public supporting facilities, and taking community space with humanistic care and simple aesthetics as the core of the spirit of living, which is a kind of exploration towards the ideal living in the future.
