Self Build Extension Kits

Flat-pack SIP home extension kits

ETZ Group supplies flat-pack SIP home extension kits for rear, side and other residential extensions. Kits are designed to help main contractors and self-builders create a warm, efficient shell more quickly than traditional build methods.

Standard kit sizes are listed below. Bespoke sizes are available on request. Prices shown are exclusive of VAT and delivery. You can order supply-only, or ask about installation within approximately 60 miles of our Kent office.

Planning permission depends on the size, location and design of the extension, and on local rules. Some projects may fall under Permitted Development; always check with your local planning authority before you order or build. Building Regulations approval is a separate requirement and must also be confirmed for your project.
