The POLYGON residential quarter on Happelstraße in Heilbronn offers modern new-build apartments in an attractive setting, ideal for singles, couples, and families. Spread across five stylishly designed apartment buildings, the development comprises 89 light-filled homes ranging from 1.5 to 4 rooms – many featuring a balcony, loggia, or terrace, with select ground-floor units offering private garden areas. The thoughtfully designed floor plans create space for individual living and a relaxed family lifestyle.
This first-occupancy 3-room apartment impresses with its clever and generous layout. It features two bedrooms, a modern bathroom with both a shower and bathtub, and a spacious open-plan living and dining area that invites you to unwind. The fitted kitchen with island unit is a particular highlight. A practical utility room with washing machine connection, a guest WC, and an entrance hallway with a dedicated wardrobe niche complete the living space. A generous loggia provides additional room to relax outdoors.
The POLYGON residential development comprises the construction of five multi-family buildings on a plot of approximately 3,287 m² on Happelstraße in Heilbronn. The project stands out for its exceptional architecture: the buildings' polygonal forms create varying eave heights and generate dynamic spatial compositions. Each façade impresses with its own distinctive appearance and massing — with no conventional distinction between front and rear elevations. A central landscaped courtyard provides access to the residential buildings and the shared two-level underground car park. All buildings meet the requirements of the KfW Energy Efficiency House 55 standard (GEG), comply with soundproofing regulations, and feature efficient ventilation systems. Constructed to EnEV 2016 standards, the buildings are equipped with thermally insulated exterior walls and green roofs. In total, POLYGON offers 69 market-rate and 20 subsidised residential units, along with 92 underground parking spaces. The apartment mix ranges from 1.5 to 4 rooms, with living areas between 35 and 147 m².
Set in an established neighbourhood with a well-developed infrastructure, POLYGON offers excellent conditions for easy everyday living. A wide range of services, discounters, social facilities, and shops in the immediate vicinity cover all daily needs. Within walking distance you'll find a bakery and supermarket, medical practices and a pharmacy, cafés and restaurants, a laundromat, a hair salon, a playground, and a fitness studio. The nearby Heilbronn Südbahnhof bus stop ensures convenient public transport connections, with bus lines 31, 32, 33, and 41 linking the Sontheim district to the city centre. Two kindergartens provide childcare for the youngest residents — and even the city centre is within walking distance. Leisure opportunities abound nearby, including the diverse Wertwiesenpark along the Neckar river, the scenic viewpoint at Ludwigschanze, and the Gaffenberg fitness trail, which offers outdoor workouts and relaxation in a natural setting.
