Innovative use of space, fluid, adaptive. It's open and shut. In and out. Across and away. Changing over time and across needs. Simple, clever, stylish. London-based architectural firm Openstudio. Of course you will remember the last project here. "Le Cabinet", Leinster Square won the Apartment Therapy Award for the "Smallest Coolest Apartment 2007". A perfect little puzzle box of an apartment. A mere 26 square metre footprint. Now that is clever!
