Welcome to
Pent Haus

We began building garden studios over 15 years ago to combine our love of the outdoors with clever design and environmentally friendly construction to make the best use of the space we have around us.

Through our extensive building & engineering experience we discovered a unique way of constructing our garden rooms that would enable DIY enthusiasts & traders alike to build a premium quality & long-lasting garden room themselves, easily & quickly.
We manufacture all of our self-build garden room packages at our factory in Mid Wales by our experienced craftsmen. All components are precision cut to suit your building.

Wiring channels are formed within the walls and ceiling for high-speed electrics and our internal packages provide CNC-cut plasterboard or wall panelling saving you the time and effort of trying to cut awkward angles in panels.

What sets the Pent Haus apart as being the best modular self-build garden room on the market?

Product excellence

Solid build

The Pent Haus is stronger than other garden rooms as each section is high-pressure bonded in a factory controlled environment. Made with our unique modular SIPs and durable ToughWood cladding, the Pent Haus is engineered to be the most long-lasting and zero maintenance garden room available.

Guaranteed fast
install speed

Through continual product development and a laser-focused dedication to precision, we have increased product performance whilst reducing stress and time on site. Our ground-breaking developments mean that your garden room can be ready in nearly 50% of the time compared to traditional building methods. With yourself and just one other person you should be able to put the structure up in as little as one day.


Every part of the Pent Haus has been designed with resilience in mind. Starting from the bottom up, they can be built on our base frame kit featuring robust ground supports which cannot rust or rot.

An envelope of insulation

Every Pent Haus is constructed with a consistent insulation layer throughout the walls, floor and ceiling. Throughout the design process we have minimised the thermal bridges to give a sealed envelope of insulation, meaning great thermal efficiency. This drives down running costs, and allows for ambient temperatures in the depths of winter and throughout our mixed British summers!
