Designed by XTH-berlin, B14 is a modern townhome located in Berlin, Germany. The house is built on a trapezoid lot of land of 118 m2 (1,205 ft2) with a small garden in the southeast towards a residential path and the wide side of the house to the northwest facing the plain of the Berlin Wall Memorial which is mainly a park. The house is all about space and light. The nearly all-over glazed facades are structured by steel girders, which span from one dividing wall to the other and take over the cross bracing. Two lines of fringy draperies in front of the ground and second floor provide screen and cover the window frames. Technically we use a heat pump (pipes going 80 mts [262 ft] into the ground) with panel heating and rainwater tanks in the garden for use in the toilet.
