Walden 48 is a six storey building in timber located in the Landsberger Allee.
The co-housing project has 43 apartment units, underground bicycle parking and communal areas, meeting the KfW 55-standard by combining energy-efficient massive wood construction and a sustainable energy concept.
The structure is made of CLT panels and wood - concrete composite ceilings, allowing an increased span length of 7,20m. Timber panels and wood fibre insulation boards constitute the outer skin of the building. Only the stairwell is built of reinforced concrete, whereas staircases, landings and all three elevator shafts are built of solid wood as well. On the street side, the double-layered wooden facade absorbs traffic noise to a large degree and faces the Landsberger Allee with a slate cladding. However on the courtyard side, an untreated larch cladding characterizes the building.
In order to provide the owners with flexibility while designing their homes, the floor plans are free of columns or load-bearing interior walls. This way a wide range of typologies including loft and duplex apartments can be realized. The house creates a connection to the adjacent park-like cemetery with spacious balconies facing its green areas.
A building the size of Walden 48, 60 meters long and 6 storeys high, emphasizes the importance of the german capital as a center of innovative urban timber architecture.
