About this project

The «Twin Relatives» project represents an intelligent housing solution for families of six or more, engineered around SIP panel technology. The ground floor hosts all common areas: an open-plan living and dining zone, a well-appointed kitchen, a dedicated home office, and two utility spaces. The entrance vestibule and ground-floor bathroom create natural flow while maintaining practical separation between shared and private zones.

The attic level accommodates four spacious bedrooms of varying sizes, perfectly suited for multi-generational living arrangements. A second full bathroom on the upper floor ensures comfort for all residents. The steeply pitched multi-gabled roof at 45° with a 10.1 m peak maximizes usable attic square footage while creating architectural interest.

The compact footprint of 21.5 × 14.8 m makes this design suitable for narrow urban or suburban lots. Nord Haus delivers and constructs this project throughout Europe, backed by rigorous quality guarantees.
