Using computer game SimCity 3000 World Edition, we want you to take control of a whole city, produce a masterplan and detailed building designs.
You'll have a big budget and SimCity's most powerful architecture design tool yet.
Winners get their schemes published and win a bottle of champagne. The AJ has six copies of the game (PC format) to give away. Fax in your request to be on the shortlist before 4 July on 020 7505 6701. Designs must be submitted by 25 July.
