The judges of the Designs on Democracy competition to reinvent the town hall, backed by the AJ, IPPR, CABE and the Design Council, have selected three winners for its sites - at Stockport, Bradford, and Letchworth in north Hertfordshire.
The triumphant practices are, respectively: ABK, Bauman Lyons and DSDHA, which defeated six other firms at the shortlisting stage.
The winners, each receiving £10,000, were announced at a ceremony on Monday night with head of judges Robin Nicholson, the IPPR's Matthew Taylor and Tony McNulty MP, design champion for the Office of the Deputy Prime Minister.
McNulty said: 'Bad design can be a barrier to participation, and all too often the poor quality of public buildings can drive people away I am delighted by this project, not only because of the sheer quality of all the designs but because they share one common aim - bridging the gap between people and place.'
An exhibition of all the winning and shortlisted schemes is on show at the RIBA until 26 January.
