On a plot in Munich previously occupied by a single-storey building, two new residential houses are being developed with a clear, contemporary architectural language and a strong ecological focus. A compact main building accommodates six efficiently organized, well-lit apartments, while a smaller second house with two units is oriented generously toward the garden, offering a particularly high-quality living environment. All required parking spaces, bicycle storage, waste areas, and a sheltered children's playground are functionally integrated into the open space concept.

The buildings are designed as an Efficiency House 55 project with an optimized thermal bridge concept, reaching a carbon footprint of approximately 24 kg CO₂e /(m² GFA · a), corresponding to the upper benchmark range of the QNG-PLUS standard. Heating and hot water are provided by air-to-water heat pumps with solar thermal support, supplemented by a photovoltaic system on suitable roof areas for electricity generation. A highly insulated building envelope with wood-fiber insulation, triple-glazed wood-aluminum windows, and carefully minimized thermal bridges ensures low energy consumption and high thermal comfort throughout the year.

Structurally, the new buildings rely on load-bearing exterior and interior walls made of clay blocks (hollow bricks), combined with substantial wood-fiber insulation and a ventilated timber façade. Clay materials, with their moisture-regulating and heat-storing properties, create a balanced indoor climate, excellent sound insulation, and improved summer comfort. In addition, recycled foam glass insulation is used for components in contact with the ground and flat roofs. This material is permanently moisture-resistant and contributes to resource efficiency.

The façade is clad with locally sourced alpine larch, whose natural greying is evenly supported and controlled by a special glaze. Carefully selected, technically dried timber boards and thoroughly ventilated substructures ensure durability and a lively appearance. Continuous window bands with wood-aluminum elements—natural oak on the inside, aluminum on the outside—with integrated shading and differentiated solar protection solutions characterize the buildings’ facades and create bright, calm living spaces that meet current standards for acoustic performance and accessibility.
