The Beursgebouw, as the first office building in Almere has been vacant for ten years. Also, Almere as the youngest city in Netherlands pay more attention on the green city development. My graduation project is to renovate the Beursgebouw in to urban farm. The new program contains two parts, one is urban farm research center and the other one is urban farm interpretation center. The part of professional urban farms will be exhibited for the public which has educational meaning for public.
