A home for a building collective
Passive Energy Plus – the StadtNatur Residential Complex in Munich

The StadtNatur building collective, which was initiated by architect Gernot Vallentin, fulfilled these conditions with a wood-hybrid construction that meets the Passivhaus Plus standard.

The residential complex stands in a cul-de-sac between a suburban railway line and a small city park. Good connections to local public transport mean that car-reduced lifestyles are possible and a ratio of 0,7 parking spots per living unit is sufficient. The complex achieved Passivhaus Plus standard thanks to the 616 m² of photovoltaic modules on the roof, a ventilation system with heat recovery, good thermal insulation and solar gains via triple-glazed, insulated windows.
The heart of the wood-hybrid building is a cross wall construction of reinforced concrete. The exterior walls, terraces, access balconies and planted roof are all of wood. Horizontal larch wood formwork and lush greenery determine the structure’s appearance: on the north side, climbing plants wind their way up wire cables; large troughs planted with bamboo divide the terraces on the south-facing side. Robins, sparrows and swifts enjoy nest boxes in the attic walls.

Thirty-seven apartments, one retail unit and a communal kitchen are distributed over three levels. While the ground-floor flats are accessed directly via a front path, suites on the upper and attic levels are reached via the stairways on the northeast and northwest sides of the building and the access balconies. These balconies are a generous 2 m wide: apart from the required emergency exits, which must remain unobstructed, they offer enough space for seating and flowerpots at residents’ doors.

The terracing of the levels has enabled a combination of apartment sizes ranging from 100 to 20 m² with the largest units on the ground floor and those above correspondingly smaller. Five one-room flats are located south of each respective stairway. The layouts of all the other apartments fill the entire width of the building; bedrooms are on the north side, and light-flooded living areas face south. The floor-to-ceiling windows extend over the entire width of each space, bringing the green of the communal garden and park inside.
