SIPs House Extensions

SIPs House Extensions

First Published: 15 February 2019
Refreshed: 17 December 2024
Reading Time: 2 minutes

Many garden room companies not only create standalone garden buildings but also design and build bespoke house extensions using SIPs (Structural Insulated Panels).

SIPs are one of the quickest ways to extend your home. A single-storey house extension can be fully installed in as little as two weeks.

SIPS House Extensions

The multi-layer construction of SIPs creates a highly insulated envelope for your new space. These extensions meet Building Regulations, and in many cases, their specifications exceed current standards. As a result, the new room often becomes the best-insulated space in the house!

With the addition of large expanses of glazing, SIPs extensions are increasingly chosen to create light-filled kitchens or sitting rooms that seamlessly flow out into the garden. Companies like Bridge Garden Rooms can even design multi-room living annexes that connect directly to your home.

Fully Project Managed Builds

Garden room companies specialising in SIPs extensions offer a fully project-managed service. They handle everything, from the initial design and any necessary planning applications to the final decoration. This comprehensive process includes installing the foundations and creating openings to integrate the extension with your main house, providing the reassurance of working with one company throughout.

While SIPs house extensions may cost slightly more per square metre than traditional alternatives, the benefits are clear. You’ll experience significantly quicker installation with minimal disruption to your home and garden. In the long term, the high thermal performance of SIPs ensures your new room is comfortable for year-round use and cost-efficient to heat and cool.
