Dimensions
External dimensions: 1.28m x 1.93m (4ft x 6ft). This 6×4 lean to greenhouse size is one of the most practical for UK gardeners, compact enough for tight spaces and urban gardens, yet offering sufficient headroom and growing area for most gardening needs.
Construction
Built from premium 12mm shiplap cladding mounted on a robust 28mm frame, this wooden greenhouse delivers exceptional durability and style. The shiplap’s tight interlocking seal provides weather-beating protection, whilst the FSC-certified wood ensures sustainable forestry practices.
Acrylic glazing offers significant advantages over conventional horticultural glass. It is completely shatterproof, making it ideal for family gardens, whilst remaining clearer and more scratch-resistant than other synthetic glazing options.
Treatment & Guarantee
The timber is pressure treated to prevent rot, backed by a superb 15-year anti-rot guarantee. This means no annual maintenance or expensive retreatment is required, leaving you more time to enjoy gardening.
Doors & Windows
Access is via a single walk-in door fitted with a drop latch and turn buttons for secure closure. The door can be installed at either end of the structure depending on your requirements and garden layout.
Assembly Information
Assembly is straightforward with fixings and instructions supplied. This greenhouse is designed without flooring, so a firm, level base is essential for optimal performance and longevity. Ensure you have a flat surface prepared before assembly begins.
