Daniel, Penketh“Helpful advice before ordering and a clear breakdown of what was included. The kit made the build much more straightforward.”
Paul C, WooltonFrequently Asked Questions
Is this supplied fully finished?
No. This is supplied as an insulated SIP shell kit. Cladding, roof covering, glazing and internal finishes can be added separately or quoted as extras.
How quickly can this size be installed?
Once the base is prepared, the SIP shell can be assembled much faster than many traditional building methods and can be ready for final cladding in as little as 5 hours with two competent people.
Do I need planning permission?
Many garden rooms fall under permitted development, but it depends on size, height, use and location. Always check your own requirements before ordering.
You can check the official guidance here: Planning Portal – Outbuildings Guide
Is it difficult to build?
No. The panels are pre-cut and designed to go together as a straightforward shell kit. Most competent DIY customers or trades can assemble the shell quickly once the base is ready.
Is delivery included?
Delivery is quoted separately. We currently prioritise delivery across the North West, with wider UK delivery available by quotation depending on kit size and location.
