Fiona Bennett has enchanted the world for almost 30 years with her hat designs. She has created her very own productions, settings for fashion shows and performances. To design the restrooms for the Wintergarten Berlin though, has been a new challenge for her. Hans-Joachim Boehme has realized temporary spaces, with architectural experience and creative impetus, since 1985. He for example, has build pavilions for the King of Thailand and created, on an area of 3000 square meters, a dignified setting for the 500th anniversary of Deutsche Post. With their collective implementation of the design of their shop, Fiona Bennett and Hans-Joachim Boehme were able to achieve their first artistic symbiosis. The First FLUSH is their second statement of extraordinary interior design.
