About this project

This sophisticated duplex harnesses the power of SIP-panel construction to create two completely autonomous residential units within a unified, highly energy-efficient envelope. Each apartment enjoys private entrance vestibules and circulation spaces, ensuring complete independence and acoustic separation. Ground floor accommodation in one unit comprises a bedroom, living room with kitchen corner, bathroom, and dedicated boiler room that services the entire household.

The mansard floor distributes 125.2 m² of additional living area across both apartments, incorporating three bedrooms, two bathrooms, and a dressing room that maximizes usable floor space proportions. Year-round construction capability means no weather delays—ideal for efficient project management.

A 40° pitched roof reaching 7.9 m at peak delivers both architectural presence and practical water drainage. The integrated two-car garage provides secure vehicle storage within the building envelope, reducing maintenance. With a minimal plot requirement of 29 × 25.7 metres, this design adapts readily to diverse European locations. Sustainable SIP materials align with modern building codes while delivering exceptional lifecycle value.
