Club Marginal Architekten Restores 1891 Berlin House with Vertical Layering

Club Marginal Architekten has renovated a semi-detached house in Berlin's Friedrichshagen district, originally built in 1891 within a protected conservation area. The project, named Friedi & Hagen, restores historical proportions while reorganizing the interior for modern family living. The attic was reconstructed and expanded with dormers to increase usable space. The facade was restored with windows featuring original cross-bar configurations. The middle floor is dedicated to the family's two children, each room incorporating a mezzanine for play and a private bathroom with orange-toned integrated furniture. The upper attic serves as the parents' area, with a large bathroom featuring a sauna, oak veneer, and travertine finishes. A freestanding travertine vanity forms the centerpiece. Flooring combines oiled pine and linoleum throughout. The intervention balances restoration, spatial reconfiguration, and material integration within the historic structure.
