Gertrudshof, a historic "Klinker Expressionist" industrial building in Berlin, has been refurbished and extended with a brutalist concrete vault structure by Berlin practice Julian Breinersdorfer Architekten in collaboration with Rimpau Bauer Derveaux.

It will soon become the headquarters for Nike Central Europe. The building, formerly a carpentry workshop, was partially destroyed by multiple bomb strikes during WWII. Comprised of three sections, only one of which remained intact, the second was partially destroyed while the third had been completely reduced to rubble.
