Each week we ask you to identify a well-known and recently completed building. To make it just a little more difficult we have had fun playing with the image. If you can decipher it, post your entry to arrive by first thing on Monday morning to The Architects' Journal, 151 Rosebery Avenue, London EC1R 4GB, or fax 020 7505 6701. The first correct entry pulled out of the hat wins a bottle of champagne.
The building featured in the last 'Spot the Building' competition (AJ 10.2.05) was the Sage music centre in Gateshead by Foster and Partners. Peter Harrison of Emsworth in Hampshire was the winner.
