Our Thermowood Garden Rooms combine premium materials, contemporary styling and exceptional build quality to create a beautifully finished, fully insulated garden building designed for comfortable year-round use.

Built using extra-heavy-duty wall and floor timbers, each garden room is externally finished in beautiful heat-treated Thermowood timber cladding, creating a warm, natural appearance that complements both modern and traditional gardens.

Fully Insulated & Built for Year-Round Use

Our Thermowood garden rooms are fully insulated throughout the walls, roof and floor. A waterproof vapour barrier and breathable construction provide additional protection against the elements while helping to create a comfortable and practical interior throughout the year.

Internally, the walls are lined with durable OSB timber boarding, while the floor features heavy-duty tongue-and-groove timber floor boarding finished with hard-wearing laminate flooring and skirting boards for a smart, practical finish.

Contemporary Doors & Windows

Each garden room is supplied with a contemporary anthracite grey PVCu 2.4m sliding door section together with a wide-opening window, providing plenty of natural light and creating a bright, spacious interior.

Double glazing and insurance-approved locks are included as standard, combining excellent security with a clean, modern appearance.

Complete Electrical Package Included

Every Thermowood garden room comes with a complete electrical package as standard, including a consumer unit, four double electrical sockets, an LED light panel and light switch, providing a practical space ready for a wide variety of uses.

Beautiful Heat-Treated Thermowood Cladding

Thermowood is created using a specialist heat-treatment process that enhances the timber's stability and durability while producing its distinctive rich brown colouring. Natural tones range from warm golden brown through to deeper chocolate shades, giving the cladding a premium and contemporary appearance.

The result is a premium, fully insulated garden room that combines natural timber styling with a high-quality interior – creating a versatile additional space for working, relaxing, entertaining, hobbies or everyday family life.
