An award ceremony generally considered to predict the shortlist has been announced this week with all five taking the top prizes.
Observers have long commented that winners of the American Institute of Architects' London Chapter design awards regularly go on to make up the final Stirling shortlist.
This year's winners were:
Peter Barber's Donnybrook Quarter
Wilkinson Eyre's City and Islington College
The John Perry Children's Centre in Dagenham by DSDHA
Zaha Hadid's Phaeno Science Centre in Wolfsburg, Germany
Richard Rogers' new terminal building at Barajas Airport, Madrid
The five winners were picked by a jury chaired by Louisa Hutton of Sauerbruch Hutton, from more than 70 entries.
Organiser and AIA veteran Chris Gaylord said he was delighted with the way the awards reflected an 'improved approach' to design in public and community architecture.
'This shows the desire of public bodies to look forward in their design approach and demand high quality, as well as affordability,' he said.
