Topaz — Energy-Efficient Home with Loft Space
A smart 277 m² residence with 2-car garage built from Nord Haus SIP panels. Four bedrooms, three bathrooms and a terrace deliver family comfort while superior insulation cuts heating costs by up to 70%.
About this project
Topaz represents the pinnacle of efficient residential design from Nord Haus, combining rapid assembly with outstanding thermal performance. The 277.4 m² layout opens with a spacious ground floor featuring an open-plan lounge, contemporary kitchen, full bathroom, boiler room and integrated double garage—all wrapped in the superior insulation of SIP construction.
The attic storey accommodates three generously proportioned bedrooms, two additional bathrooms and utility space, perfectly suited to growing families or multi-generational living. A 30° pitched roof with an 8.8 m ridge creates an airy upper level and refined exterior proportion. SIP panels regulate interior moisture organically and maintain stable temperatures year-round, dramatically reducing reliance on mechanical climate systems and lowering operational costs.
Year-round construction capability means site mobilisation is not weather-dependent, accelerating overall project timelines. A modest plot requirement of 23.9 × 23.6 m slots efficiently into standard suburban settings across Europe. The generous terrace on the ground floor seamlessly transitions living space outdoors, ideal for entertaining and seasonal gatherings.
