Project description

Modern
townhouses & condominiums
in Hamburg – Groß Flottbek.

Design meets nature:
Exclusive living in Hamburg-Groß Flottbek
The Backyard Oasis new build project in Hamburg-Groß Flottbek comprises a total of 15 high-quality residential units: four townhouses and two semi-detached houses at Seestraße 20, along with a multifamily residence with nine condominiums at Groß Flottbeker Straße 65. Modern architecture, clean lines, and generous floor plans combine an urban lifestyle with a nature-inspired living experience. Ideal for families, couples, and discerning owner-occupiers who value quality, location, and living comfort.
Townhouses
The townhouses extend over three floors with four rooms and spacious terraces directly connected to the open, light-filled living and dining areas. Floor-to-ceiling windows and charming bay windows create a bright, inviting atmosphere. The view of the adjacent biotope lends the homes a sense of peace and proximity to nature. High-quality flooring, modern bathrooms, and smart layout details emphasize the elevated living standard.
The top floor features a spacious master bedroom with walk-in dressing room, en-suite bathroom, and direct access to the approximately 16 m² rooftop terrace – a private retreat with green views.
Semi-detached houses
The semi-detached houses offer a similar layout with four rooms and south-facing terraces and rooftop terraces that enjoy sunlight throughout the day. Large windows, open floor plans, and modern features such as vertical window blinds create a comfortable, contemporary living atmosphere.
Condominiums
The multifamily residence at Groß Flottbeker Straße 65 includes three ground floor units and six maisonette apartments, each with four rooms. These units also feature thoughtful layouts, bright living areas, and a high-quality outfitting standard. The underground garage offers convenient parking directly on the property.

Sustainability and energy efficiency
Sustainability and energy efficiency are at the heart of Backyard Oasis. All units are equipped with air-source heat pumps, photovoltaic pre-installation, triple-glazed timber windows, and a controlled ventilation system with heat recovery. Wallbox pre-installation at parking spaces supports forward-looking e-mobility.
Backyard Oasis combines nature-inspired living with modern comfort – right in one of Hamburg’s most sought-after districts
The buildings feature a modern external thermal insulation system, efficient air-source heat pump, and pre-installed photovoltaic systems. Controlled ventilation with heat recovery ensures a pleasant indoor climate. Parking spaces are pre-equipped for electric car charging, and an alarm system pre-installation is included. A built-in intercom system completes the technical outfitting. Many units also enjoy particularly attractive views into the green biotope.
Outfitting
that brings long-term joy

Outfitting
The outfitting of the residential units impresses with a stylish blend of premium design, modern technology, and thoughtful functionality.

Comfort features include underfloor heating with individual room control, dimmable light switches, and flush-fitting doors. The sophisticated bathrooms are outfitted with Dornbracht fittings and walk-in showers, complemented by guest WCs in every unit.
Floor-to-ceiling triple-glazed timber windows with integrated vertical blinds, concealed fittings, and safety glass on the ground floor ensure bright interiors, security, comfort, and energy efficiency. Electrical connections for terrace sunshades are pre-installed, as are exterior water taps.
