Luxury residence over two levels with private south-facing garden paradise

This luxury garden duplex maisonette, built in 2025 and situated in an absolutely quiet cul-de-sac in Cologne-Deckstein, completely redefines the concept of urban living, combining stately elegance with a fascinating “house-within-a-house” feel. On approximately 154 m² of perfectly designed living space, you can enjoy the comfort of a classic semi-detached house combined with the benefits of an exceptionally low-maintenance premium property. A particular highlight is the impressive ceiling height of up to 2.69 metres, which, together with the floor-to-ceiling aluminium windows, creates an unparalleled sense of spaciousness and abundant natural light. The uncompromising, state-of-the-art technical infrastructure of this first-occupancy property has already been fully completed, while you have complete freedom in the final interior design. The rooms are presented in a high-quality unfinished condition, allowing you to select and install the flooring and sanitary fittings according to your personal preferences—whether timeless herringbone parquet or large-format porcelain stoneware. The centrepiece of the ground floor is the expansive living and dining area, which opens seamlessly onto the approximately 25 m² sunny terrace. From here, you access your approximately 275 m² secluded south-facing garden oasis for your exclusive use, which even has a separate, lockable outdoor entrance for maximum convenience. You can reach the upper floor via an elegant staircase or completely step-free by lift with personalised access authorisation. Here you will find the private master suite, two further flexible rooms—ideal as children’s bedrooms or a prestigious home office—as well as a practical utility room and access to the private south-facing balcony. In terms of technology and energy efficiency, the residence sets an absolute benchmark for the future: a dedicated air-to-water heat pump with hot-water storage ensures complete independence, while the underfloor heating system offers a cooling function in summer. A KNX bus system fully automates your smart home independently, complemented by controlled residential ventilation with heat recovery and keyless fingerprint access. This rare offering is completed by a private basement storage unit with high ceilings and two generous parking spaces in the building’s underground garage, including provision for e-mobility, conveniently accessible via the car lift.
