Freiburg: Quantum Concludes Forward Deal for 64 Subsidized New-Build Apartments

Hamburg, October 6, 2025 | Quantum Immobilien KVG has signed a forward deal for a subsidized new-build in Freiburg im Breisgau. The ongoing project development comprises 64 subsidized rental apartments which, upon completion, will be transferred to a fund managed by Quantum. The seller is Unmüssig Bauträgergesellschaft Baden mbH.

“We are delighted to expand our investor’s portfolio with this acquisition in Freiburg’s rapidly growing residential market,” says Martin Berghoff, Managing Director at Quantum, adding: “The property’s construction quality and fit-out will fully meet the standard of privately financed residential buildings, thereby creating high-quality and affordable housing.”

High-demand housing in Freiburg

On a plot of approximately 4,215 m² at Haierweg 52 and 54, directly adjacent to the development of the “Am Lindenwäldle” urban quarter, 64 subsidized rental apartments are being built. According to current plans, these will be distributed across three buildings with four floors each (including the ground floor), plus an underground parking garage with car parking spaces.

The average size of all 1- to 4-room apartments is around 79 m², with a majority of 3- to 4-room units planned. In total, the new-build will offer a rental area of approximately 5,000 m². All apartments are planned to feature high-quality specifications, including real-wood parquet flooring, underfloor heating, fitted kitchens, and modern bathroom fixtures. In addition, each apartment will have a balcony or terrace facing southeast.

“With this project development, we aim to create affordable housing in Freiburg’s rapidly growing west, thereby helping to ease the local housing market. Creating sustainable, high-quality residential space is important to us in the context of developing the entire Haslach district. We would like to thank Quantum for once again placing their trust in our long-standing business relationship,” says Hans-Peter Unmüßig, Managing Director of Unmüssig Bauträgergesellschaft Baden mbH.

Completion by the end of 2027

The new-build is scheduled for completion by the end of 2027. The façade is designed as a highly insulated external thermal insulation composite system with brick slips, uPVC windows, and triple insulating glazing. Heat pumps and a supplementary photovoltaic system on the roof are also planned. All measures contribute to achieving a KfW 40 efficiency house in line with the QNG sustainability standard.
