All Hawksbeck Garden Rooms are made using Structural Insulated Panels (SIPs). SIPs are the most advanced building technology system used in construction today.

By partnering with a leading SIP manufacturer, who are industry accredited and award-winning (see below), we ensure that each garden room is built to the highest standard and built to your exact requirements. We are proud to be one of the few garden room manufactures building to building regulations standards and in many areas exceeding these requirements.


What are SIPS?


Structural Insulated Panels (SIPs) constitute a high performance building system that is very strong and highly energy efficient. They are also used in the manufacture of residential homes and commercial buildings. SIPs are up to 7 times stronger than timber frame buildings and up to 3 times stronger than brick built homes.

Sedum roof

Firestone roofs


Firestone EDPM, is our standard roof option, it gives an excellent waterproof barrier to your garden roof structure and is specially designed for flat or low-sloped roofs. It is a durable rubber roofing membrane which is used worldwide. It has a life expectancy of more than 50 years with a 30 year weather security guarantee.

Sedum roofs


A sedum roof, sits on top of an EDPM roof, and is a great way to finish your garden room. From an aerial perspective, sedum roofs blend with your garden, are environmentally friendly and give great insulation. The Hawsbeck Garden Room here is finished with sedum that has been grown on the shores of the Irish Sea by our excellent sedum roof supplier. The harsh environment creates the strongest most hardened living roots available on the market.

Cladding Options

We offer multiple different cladding options, our two most popular are cedar and cement fibre board.

Cedar cladding is a natural and sustainable product. It is a very effective insulator, requires very little maintenance and it lasts for decades. Best of all cedar cladding looks great and can be stained almost any colour.

Cement fibre weatherboard is a low maintenance, rot free alternative to traditional timber weatherboarding. It comes in a range of 23 factory applied colours, and has a life expectancy of 50 years.
