About this project

The «Next Door Twins» project exemplifies smart semi-detached living, where two complementary dwellings share thoughtful symmetry. Built with SIP panels, this home delivers exceptional insulation properties and airtightness, dramatically reducing heating requirements year-round. The material system enables construction regardless of season, a significant advantage across diverse European climates.

The ground floor hosts all essential living zones: an expansive living room, open-plan kitchen, home office, two bathrooms, and single-car garage. A welcoming entrance hall and dedicated boiler room enhance everyday functionality. The attic level accommodates three bedrooms, a walk-in wardrobe, and a second bathroom—perfectly suited for families seeking room to grow.

At 180.8 m² total with an 8.4 m ridge height, this design maximizes spatial perception and natural light throughout. The minimum plot requirement of 20.9 × 15.5 m makes it ideal for suburban developments with space constraints. SIP-panel construction delivers ecological benefits, structural longevity, and waste minimization—aligning with Nord Haus's commitment to sustainable European building.
