SIP Panels

You will receive SIP panels at the size you ordered, but will need to order accessories and extras such as breather membrane, joining splines and cladding as appropriate, which you can purchase through us if you prefer.

Yes, you can collect from our workshop in Gloucestershire or we can deliver to kerbside at the property.

DIY Garden Room Kits

Yes, we can adapt any of our standard rooms or create a bespoke kit to your size and specification, which we will provide a price for.

We provide a comprehensive installation guide with every room.

You will need to consider the type of base that your self-build garden room kit will be constructed on. Typically, we would expect you to need one of three types of foundation: pad, ground screws existing/new concrete base. You can use adjustable feet to level off the base.

The kit you have ordered will include the elements that are applicable to that kit and the SIP panels will be cut to size, ready for installation. Kits are delivered to the kerbside at the property.

Most rooms will not require planning permission and will fall under Permitted Development rights. However, if you are unsure, please seek guidance from your Local Planning Authority.

Cedar and Thermowood cladding are maintenance-free. Tanalised Redwood will require treatment throughout its life.

On our Shell + External Kit and Complete Kit we include UPVC glazing. We offer a choice of sizes of glazing. As an upgrade, we also offer aluminium windows and bifold doors.
