Barcelona, Spain –- Guallart Architects has won the international competition for the design a mixed-use community in the Xiong'an new city (China), defining a new standard in the post-Covid era, that can be applied as a raw model in different cities around the world.

The proposal presented under the title “the self-sufficient city”, defines an urban model, that merges the traditional European urban blocks, the Chinese modern towers, and the productive farming landscape. This new urban environment where people can live, work and rest, will allow their residents to produce resources locally while they are connected globally, providing a full life even in moments of confinement.

“We cannot continue designing cities and buildings as if nothing had happened,” said Guallart, “Our proposal stem from the need to provide solutions to the various crises that are taking place in our planet at the same time, in order to create a new urban life based in the circular bioeconomy that will empower cities and communities”.

Specifically, the project is conceived as layers of onions, defining different functions needed for human life at different scales, from the home, to the building, to the community. The four blocks, that will be built using mass timber and passive design solutions will have mix use program including apartments, residences for young and old people, offices, swimming pool, shops, food market, kindergarten, administrative center and a fire station among other facilities.

All buildings will be covered by greenhouses that will allow to produce food for daily consumption and use their sloping roofs to produce energy. In the ground floor, small co-working digital factories will allow to use 3d printers and rapid prototyping machines to produce object for the daily use. So the building will have an internal metabolic system that will integrate energy production, recycled water, food production and material reuse promoting a distributed model for urban management.

All the apartments will have a large terrace facing south, which acts as a thermal regulator, and will be a fundamental space in periods of confinement allowing the residents to play, rest and work. Likewise, the homes will be prepared to have telework spaces and will be connected to 5G networks, creating social networks at neighborhood-scale for the exchange of resources.
