Extend Edge Composite Garden Rooms

The Extend Edge Garden Room - a practical, modern design that combines a glass corner feature with a 0.5m roof canopy running across the full front of the building, bringing light, shelter, and a strong connection to the outdoors.

Our Extend Edge composite and timber garden rooms are constructed using extra heavy-duty wall and floor timbers for exceptional strength and durability. Fully insulated walls, roof, and floor are complemented by a waterproof vapour barrier wrap and breathable wall membranes, ensuring excellent thermal performance and a dry, condensation-free interior.

Internally, the garden room walls and ceiling is professionally plaster boarded and plastered inside just like a new house. The floor is finished with industrial-grade tongue-and-groove timber flooring. This is completed with durable laminate flooring and matching skirting boards, creating a practical yet refined interior finish.

Each Extend Edge Garden Room is supplied with a dark grey (anthracite) PVCu 2.4m sliding door section and a wide-opening window. Double glazing and insurance-approved locking systems are included as standard, delivering security, natural light, and ease of access.

Every garden room includes a complete electrics package as standard, featuring a consumer unit, four double electrical sockets, an LED light panel, and a light switch - ready for immediate use as a workspace, studio, or relaxation area.

Choose from a range of sizes and external cladding options, including Smoothgrain and ProClad Woodgrain composite cladding, or Thermowood and Western Red Cedar timber cladding. Please Note: Some images may show options not included as standard.
