Forest Garden Wallscape 4ft x 8ft Lean To Greenhouse with Open Back

The Forest Garden Wallscape 4' x 8' Lean To Greenhouse (LTGH48HDBUN) is built for courtyards and patios where space is tight. At 1.28m x 2.52m it gives you a real working footprint enough floor space for two grow bags and staging along the back wall. Its open-back design lets you position it flush against a wall or fence with no wasted clearance behind it.

The frame is 28mm x 28mm pressure treated timber clad in 12mm shiplap tongue and groove boards. That tight interlocking shiplap seal keeps the interior dry even in heavy rain. Glazing is shatterproof scratch-resistant acrylic lighter and safer than horticultural glass and clearer than standard polycarbonate. The timber is FSC certified and UK constructed. A 15-year anti-rot guarantee is included with no further treatment needed.

A large opening roof vent regulates temperature through summer. The single door fits at either end of the structure to suit your layout. There are 7 windows total. No staging is included but a wooden potting bench is available separately. You can realistically grow tomatoes, peppers, cucumbers and overwinter tender plants in this size.

The pent roof, pressure treated frame and acrylic glazing make this a low-maintenance lean-to that works hard in a small space. FSC timber, 15-year guarantee and free UK delivery make it a solid buy.

The 28mm x 28mm timber frame is clad in 12mm shiplap tongue and groove boards. The tight interlocking profile of shiplap cladding creates a weather-resistant seal that keeps rain out without relying on sealants. The pent roof pitches away from the wall and is glazed with 28mm acrylic. Acrylic is lighter than glass and will not shatter into sharp fragments. The roof vent is hinged and opens manually. The pressure treatment penetrates the timber to resist rot from the inside out rather than just coating the surface which is why the 15-year guarantee requires no retreatment.

The frame is 28mm x 28mm FSC certified pressure treated timber finished rough sawn. Cladding is 12mm shiplap tongue and groove. Glazing on the walls and roof is shatterproof scratch-resistant acrylic not glass. The roof acrylic is 28mm thick. The greenhouse is constructed in the UK.

This greenhouse has no floor included. You must prepare a level base before assembly a concrete slab or level paving is the recommended approach. The buyer is responsible for ground preparation. No base or flooring is supplied with the greenhouse.

This greenhouse arrives flat packed. Fixings and instructions are included. No assembly time is stated by the manufacturer but given the 130kg packaged weight and the size of the structure it is a two-person job. No specialist tools are mentioned. Professional installation is available as an optional service through the retailer.

The 1.18m x 2.42m base gives you enough floor space for two standard grow bags side by side that is four to six tomato or pepper plants on the floor alone. A potting bench along the back wall (available separately) adds a full-length work and staging surface for seed trays and pots. In spring use it for sowing seeds and raising seedlings. Through summer it handles tomatoes, cucumbers and peppers well. In autumn and winter it will protect tender plants, overwintering fuchsias, pelargoniums and citrus from frost.

The pressure treated frame needs no annual retreatment the 15-year anti-rot guarantee covers this. Clean the acrylic glazing with a soft cloth and mild soapy water to keep light transmission high. Check the roof vent opens freely each spring. Keep the base clear of standing water and debris.

The open-back design is the key space saver here. The back of the greenhouse sits against your wall or fence so you lose no garden depth behind it. You need clearance at one end for the door to open roughly 600mm is sensible. The pent roof slopes away from the wall so it will not clash with fence panels or eaves above. The 1.28m width is narrow enough for a side passage or patio edge.
