Passive house on the Linienstraße in Berlin

The building at Linienstraße 23 combines an art gallery on the first floor and airy maisonette apartments on the floors above under one roof.

The entire shell is kept in one color tone: Plaster, doors and windows, blinds, even the house number, bell panel, and garden stairs – all façade elements are stone gray. This underscores the principle of the passive house: The tightly closed building shell. The façade is brightened up by large window openings that extend out of the building's alignment, as well as a large balcony facing the garden. 

“We were only able to realize the cantilevered and delicate design of the 7.22 x 1.50 meter balcony with the help of a structural element that has both sufficient load-bearing capacity and prevents undesirable thermal bridges,” explains Dipl.-Ing. Johannes Gotaut from BCO Architekten in Berlin. “To meet the strict passive house specifications, we also thermally separated the wall and ceiling connections for the unheated access to the underground garage with the Schöck Isokorb® XT type Q.” Schöck Isokorb® XT type K 40 is used on the balcony.
