“Selective Insulation” is a project by the architects Davidson Rafailidis. They developed this small study as a room in a room, which is in a big difficult to heat, old school building. The shape is defined by a few parameters: the daylight conditions, 2 people need a minimum of 4m² desk-related office space and they wanted to have desk, a window and a way to enter/exit. The whole framework is quite simple and wrapped with an insulating layer of double-ply bubblewrap.
