German firm Sauerbruch Hutton has won a competition to design Finland’s first carbon-neutral district.

Sauerbruch Hutton has collaborated with design firm Arup to create the ‘c_life – City as Living Factory of Ecology’ in the 100ha district of Jätkäsaari.

The design involves building flexible, low-carbon buildings, community gardens and greenhouses that will emit 47% less carbon dioxide than other Helsinki residences by 2037.

An off-site wind farm will offset the remaining carbon emissions in the area.

A funding model for development has also been developed alongside the design proposal.

The first phase of the project is due to be finished by 2012 while the entire district is expected to be complete by 2023.

The Low2No competition has been organised by Sitra, a Finnish innovation fund.
