A residential project with clear prospects for sustainable appreciation is taking shape at Bonner Straße 540 in Cologne-Marienburg: a striking standalone building at Cologne’s southern gateway with 32 residential units, which is being made future-proof through comprehensive modernization measures.
The building is undergoing a complete energy-efficiency overhaul: new windows, a modernized facade with green roofing, a new roof, and renovated balconies. In the future, efficient heating will be provided by an intelligently controlled hybrid system combining gas central heating with a connected air-to-water heat pump—a resource-efficient and future-proof solution.
About half of the apartments are currently vacant and are undergoing extensive renovation. This will result in modern, optimized floor plans, underfloor heating, high-quality hardwood floors, and contemporary bathrooms. Once the work is complete, the condominiums will be sold move-in ready and fully renovated—with light-filled rooms and high-quality finishes.
The building itself is also undergoing a fundamental modernization. New burglar-resistant apartment entry doors, a modern fresh water station, a complete renovation of the drinking water pipes, and connection to the new heating system will enhance comfort, security, and efficiency. In addition, the building’s entrance area will be extensively renovated and aesthetically upgraded, creating a prestigious first impression and further enhancing the overall quality of the property.
Ideal as a new home or as an attractive investment.
