Easy-build DIY 
garden rooms

Build your own now

Our self-build DIY garden rooms include:

The Frame


Your structure will include the floor, walls and roof which constructed using structurally insulated panels (SIPs) which offer highly efficient thermal values and exceptional strength. The wall thickness is 100mm & the floor is 130mm, making our studios warm in the winter and cool in the summer, with good sound-proofing.

Wiring channels are also formed & concealed within the walls and ceiling for high-speed electrics and a smooth interior finish.

Windows & doors

Upgrades include sliding or bi-fold doors in aluminium frames, additional windows and full length picture windows. High security locks are fitted to doors and windows, giving you peace of mind that your valuables will be kept safe & secure.

The roof

The roof is composed of 125mm thick insulated SIPS panel and covered with highly durable EPDM rubber, with plastisol-coated steel anthracite edging. The roof pitch has a slight slope from front to back, allowing water to run off efficiently to the rear guttering system and downpipe.  We provide 4” wide guttering is provided as standard to manage the flow of water from the roof and away from your garden room.



We clad the exterior of our studios with ToughWood™ cladding which we manufacture in various contemporary and woodgrain effect colours. ToughWood™ is an engineered wood, manufactured from wood strands compressed under extremely high pressure and bonded together to create an ultra-tough dense and stable cladding. It looks like wood, but has none of the disadvantages of natural wood! Made from sustainable resources, it’s the ecologically responsible choice compared to PVC or composite cladding.


Our garden room kits are available with plasterboard for a plastered finish or tongue & groove wood panelling. Both of which can be painted in your chosen colour.

We CNC-cut your chosen interior finish saving you the effort of trying to cut awkward angles in panels. Our cleverly designed SIP panels have a unique concealed wiring system ensuring you are left with a smooth joint free finish.

Your Pent Haus will come included with accessories to complete your build. The 3 kits that are included as standard are:
