Architects Pieter and Silvia Mertens took a 8’ wide space between two buildings, erected a steel skeleton in it and installed four wooden floors, one each for work, dining, relaxing and sleeping, plus a bath tub on the roof. Two concepts arise from this Coolhunter Blog post: Voyerism and Sustainablity. First, this building puts all parts of their lives on public display. We are living in a world were the rules of privacy are constantly changing and adapting. Second, they have successfully maximized the use of a space not traditionally intended to be habitable.
