Cologne, January 22, 2026. The wvm Group is developing new housing at Rhöndorfer Straße 4 in Cologne-Sülz. On the approximately 3,720-square-meter site, the company plans to develop a modern residential project comprising a total of 100 privately financed residential units. Completion is scheduled for late 2029.
The plans include 1- through 5-room apartments, all of which will have their own outdoor seating area.
About 55 percent of the units are 1- and 2-room apartments, which could be attractive to investors. Thanks to the proximity to the university and excellent local amenities, this residential development specifically addresses the high demand for smaller apartments in urban locations.
The building complex comprises five stories, including a stepped story. All full stories facing the street will feature a high-quality clinker brick veneer facade.
The underground parking garage will have 53 parking spaces, all of which will be equipped with charging points—making the project fully e-mobility-ready.
Sustainable Energy and Open Space Concept
The energy supply concept focuses on resource conservation, sustainability, and efficiency. Heating and hot water are provided by low-noise, highly efficient brine-water heat pumps. These are powered by heat and electricity from modern PVT modules (photovoltaic and solar thermal) on the roof.
The wvm Group is planning to meet a high energy standard in accordance with the current requirements of the Building Energy Act (GEG) and is evaluating various subsidy and certification models while taking ecological, economic, and sociocultural aspects into account.
The currently fully paved lot will undergo comprehensive ecological enhancement as part of the development: Plans include planting approximately nine new trees, as well as various shrubs and grassy areas, green roofs, and the removal of paving from about 20 percent of the site, which will be converted into green space. The sheltered private courtyard with a playground for young children will enhance the quality of life for residents.
Project Developer Chooses a Familiar Location
“We feel right at home on Rhöndorfer Straße,” says Erika Werres, managing director of the wvm Group. “We have already completed several successful residential projects in the immediate vicinity. With this new project, we are building on that experience and creating more urgently needed housing in an attractive Cologne location.”
