Extend your home with a lightweight, accurate and thermally efficient SIP structure.
Suitable extension types
Rear extensions
Open-plan kitchens, dining rooms and family spaces with wide garden connections.
Side and wraparound extensions
Maximise underused side returns and reorganise the ground floor.
First-floor additions
Lightweight panel construction can be advantageous where loads and access need careful control.
SIP roofs and infill structures
Highly insulated roofs, gables and structural envelopes integrated with existing buildings.
Integration with the existing home
Extension projects require careful survey and engineering work. We consider existing foundations, wall construction, drainage, roof geometry, movement, temporary support and the size of new structural openings. SIPs are then detailed as part of the overall structural design rather than treated as an isolated product.
What we provide
Our service can cover feasibility, architectural design, planning, Building Regulations, structural calculations, panel detailing, manufacture, delivery and erection. We can work directly with homeowners or alongside an appointed architect, engineer or main contractor.
