In a narrow gap of only 3,3 meters between two existing houses in Offenbach am Main a series of student houses

are build after five strategies to minimize costs:

• Only two supporting walls.
• Transparency for maximum daylight.
• One core for all water- and air circulation.
• A system of columns to support flexible low cost inner walls.
• An external system for all cables.

The students will share a roof terrace with a small garden and outdoor kitchen overlooking the skyline of Frankfurt. The building is made from a light weight concrete and only supported by four narrow columns on the ground floor maintaining the current access to the shared courtyard.

The balconies are cut in a 45 degree angle due to regulations on privacy and views to the neighbors.
