The theme for Europan 9 is 'sustainable cities and new public spaces' and judges have been asked to look for 'housing design which is resource-efficient and will adapt to climate change, and which makes a positive contribution to local communities.'
The varied sites include a 'first phase' waterside regeneration scheme in Stoke-on-Trent; a 'skyline' development just outside Sheffield city centre; and a development site within the expansion area of Milton Keynes.
Entrants will be hoping the contest - which has had a notoriously unproductive history - will be more successful than in previous years.
Eyes will be especially focused on the 2.4ha Fairfield site in Milton Keynes, following the uncertain outcome of Europan 8 (AJ 16.02.06). In the last competition the panel judging the entries for another plot in Milton Keynes was unable to choose an outright winner, leading to a battle between the two runners-up which continues to rumble on almost a year later.
Among this year's judges will be Peter St John of Caruso St John Architects; Neave Brown of Neave Brown Architects; and Christine Hawley, dean of the Bartlett.
The deadline for registration is 31 May and more information about the competition can be found at www.europan.org.uk
