To coincide with the Le Corbusier's Cabanon exhibition taking place at the RIBA, Blueprint and Cassina have launched a competiton for visitors to design their own retreat.

Le Corbusier drew the initial sketches for the Cabanon in just 45 minutes. Blueprint asked a series of today's leading architects to imagine their own retreat, and sketch this for them in 45 minutes. See images and videos of these modern-day cabanons on the Blueprint website|.

Pick up a postcard from the exhibition to submit your design for a chance to win a Cassina LC3 anniversary chair originally designed by Le Corbusier, Pierre Jeanneret and Charlotte Perriand.

Deadline for entries is 28 April 2009.

Postcards can be mailed out on request. UK entries only.
