Forest Garden Wallscape 4ft x 6ft Lean-To Greenhouse with Open Back

The Forest Garden Wallscape is a 4ft x 6ft lean-to greenhouse with a footprint of 1.28m x 1.93m. LTGH46HDBUN is the open-back variant, designed to sit flush against a wall or fence. That footprint gives you a usable floor run of just under 2.5 square metres genuinely workable in a small courtyard or patio garden. The open-back design means you lose no garden space to clearance on the rear side.

The frame is rough-sawn timber on a 28mm x 28mm section with 12mm shiplap tongue-and-groove cladding. The shiplap's interlocking profile keeps the interior dry. Pressure treatment is applied at the factory and the 15-year anti-rot guarantee means no further treatment is needed. Timber is FSC certified. Glazing is acrylic shatterproof and scratch-resistant covering 6 windows plus the roof at 28mm thickness.

A large opening roof vent regulates temperature inside. There is no auto vent included. The single door can be fitted at either end of the structure to suit your layout. No staging is included but a potting bench is available separately. You can realistically grow tomatoes, peppers and cucumbers on the floor with seedlings on added staging.

This greenhouse is built in the UK from FSC timber with a 15-year anti-rot guarantee. Fixings and instructions are included for straightforward DIY assembly. No floor is supplied so a prepared base is needed.

The frame uses 28mm x 28mm rough-sawn timber sections a solid size for a lean-to this scale. The 12mm shiplap tongue-and-groove cladding interlocks tightly to keep rain out without relying on sealant. Acrylic glazing at 28mm roof thickness is lighter than glass and will not shatter. The pent roof pitches away from the wall to shed water. The single manual roof vent is hinged to open for temperature control. Pressure treatment penetrates the timber fibres to resist rot from the inside out rather than just coating the surface.

The frame is rough-sawn FSC-certified timber on 28mm x 28mm sections clad in 12mm shiplap tongue-and-groove boards. All timber is factory pressure treated. Glazing across 6 windows and the roof is shatterproof scratch-resistant acrylic. The roof acrylic is 28mm thick. No glass is used anywhere in the structure.

No floor is included with this greenhouse. You must prepare a solid level base a concrete slab or paving to the base dimensions of 1180mm wide by 1826mm deep before assembly. The buyer is responsible for preparing the ground. No base or flooring is supplied with the greenhouse.

This greenhouse arrives flat packed with all fixings and instructions included. It is a DIY assembly job professional installation is not included as standard though it is available as an upgrade. Two people are strongly recommended given the 115kg packaged weight. Most competent DIYers complete the build in a day. Instructions are clear and all fixings are provided.

The floor area of 1.18m x 1.83m fits two standard grow bags side by side running the length of the greenhouse. That gives you space for six tomato or pepper plants on the floor. Add a potting bench along one side and you gain a shelf for seed trays in spring realistically 20 to 30 modules at once. In summer use the floor for cucumbers and climbing tomatoes. In autumn and winter use the bench for overwintering tender perennials and half-hardy plants that just need frost protection.

The timber is factory pressure treated so no annual retreatment is needed. Clean the acrylic glazing with a soft cloth and mild soapy water to maintain light levels. Check the roof vent opens and closes freely each spring. Clear any debris from the roof and check the shiplap joints stay tight. No additional preservative is required to keep the 15-year guarantee valid.

The open-back design removes the need for any rear clearance the greenhouse sits directly against a wall or fence. You need roughly 600mm at the front to open the door and enough space at your chosen door end for access. The base footprint is just 1.18m x 1.83m yet the interior gives you a full standing-height growing space with eaves at 1891mm. It works well in a corner with the wall forming the back and one side.
