SOL House, a residential project designed by Alexander Brenner Architekten in Stuttgart, Germany. Completed in 2013, the house is a 433 m² residence that blends with surrounding 1930s architecture. The design includes advanced energy systems, including geothermal heating and solar power, alongside a focus on simplicity and high-quality materials.
SOL House is located along a residential road in Stuttgart, characterized by buildings from the 1930s, typical of the city’s hillside areas. The residence respects the scale and solid nature of the neighboring two-story cubic houses, though the street-facing facade is largely closed to meet modern living needs.
On the upper level, secondary rooms and spaces that require minimal natural light are positioned on the street-facing side. The facade features protrusions, recesses, a cantilevered roof slab, and various surfaces that extend into outdoor areas, creating a dynamic, layered appearance for those passing by.
A long building section beneath the house, which houses garages and secondary rooms, shields the garden from public view. In contrast, all living spaces open downward towards the forest to the south.
The ground floor includes communal spaces such as the kitchen, dining, and living areas. The upper level is designated for guests and the parents. Utilizing the cross slope of the site, both the ground and garden levels have direct access to the southeast garden. The garden level is designed for children’s areas and includes a sauna with a relaxation room.
The southeast-facing roof overhangs and continuous loggias on the upper and ground floors offer protection from summer heat while allowing passive solar gains in winter. The house is heated by a geothermal system, with solar energy used for hot water and pool heating. Photovoltaic systems generate the required electricity.
The clients prioritized the use of advanced technology, sustainable energy solutions, and a design that emphasized simplicity, timelessness, and high-quality, durable materials.
