Sonnenquartett

In tune with nature: Four multi-family dwellings – collectively known as the sun quartet – are in the process of being built in two construction stages in a marvellous location on the edge of Freiburg-Ebnet. Thanks to its position and layout, this residential area offers a unique panoramic view out over the Dreisamtal Valley and up to the mountainous Black Forest. The housing options include 44 gorgeous freehold flats between 48 and 117 m² large with 2 to 4 rooms each. With a primarily open floor plan, these spacious dwellings receive lots of direct and indirect sunlight.

The project was designed by Eble Messerschmidt Partner, an architectural firm in Tübingen which has been working on linking energy-efficient, healthy and resource-saving construction with contemporary design for over 30 years.

The sun quartet sets an example in sustainable architecture

The multi-family dwellings are characterised by an innovative energy concept and a pioneering wood hybrid design. Building materials such as wood and reinforced concrete are combined to complement each other’s strengths. This method of construction supports the circular economy which is becoming ever more important in civil engineering and enables a high standard of thermal insulation. The wooden façade pays homage to the building arts traditions of the Black Forest and lends sun quartet a note of authenticity against its natural background. Soft, gently transitioning hues underscore the buildings’ lively and varied flair. The wooden window frames and flooring in the flats’ interiors also reflect the façade's natural character, promoting high-quality and healthy living.

A photovoltaic-thermal (PVT) hybrid system combined with a heat pump supplies the buildings’ energy. Electricity generated on-site from solar energy is converted into heat, which is supplied to each flat in a fully carbon-neutral process.
