About
About Pent Haus
Pick a size, choose your cladding and roof, and decide where the doors go: the whole kit arrives on your drive, ready to build.
Every Pent Haus is made from ToughWood composite, with aluminium-framed glazing and an insulated rubber roof. The low pent roofline sits within most permitted development height limits, so planning permission is rarely needed.
- Three builds: ToughFrame, insulated ToughFrame Pro, and Signature SIPs panels
- ToughWood cladding in six colours, which never needs retreating
- Double-glazed aluminium windows and doors
- Panels no wider than 600mm, so a kit can be carried through the house
- Built in 3 to 5 days by two people

Help
Help with your Pent Haus building
Allow 3 days to build a Signature SIPs kit, or 4 to 5 days for ToughFrame and ToughFrame Pro. You will need at least two people.
Do I need planning permission?
Usually not. Pent Haus rooms are designed to sit within permitted development rules. If your property is listed or in a conservation area, check with your local authority first.
Are foundations included?
No. Add the Foundation Pack in the configurator, or build on your own concrete base.
What does the kit include?
The structure, ToughWood cladding, the EPDM roof and guttering pack, double-glazed aluminium windows and doors, and your chosen internal finish.
Can I run electrics to it?
Yes. Add the Electrical Pack in the configurator. Any connection to the mains must be made by a qualified electrician.
Can I have a bathroom or kitchen?
Plumbing is not part of the kit. You would need to arrange that separately once the room is built.
Can I have internal walls?
Yes. Partitioned stud walls are available on the 4.8m and 5.4m wide models.
What if there is no access to my back garden?
Every panel is 600mm wide at most, so a kit can be carried through a house. The longest panel is 5m.
