Forest Garden Georgian Tall Wall Lean-to Greenhouse with Auto Vent 4ft x 2ft

The Forest Garden Georgian Tall Wall Lean-to Greenhouse (GEORGEWGHAVHDBUN) has a footprint of just 1.04m x 0.44m at the base that is roughly 3ft 5in x 1ft 5in. For a small garden or tight patio space this is a genuinely practical growing area without taking over the whole plot.

The frame is built from 12mm tongue and groove PEFC-certified timber with a smooth-planed finish. It is pressure treated using a vacuum and hydraulic process that forces preservative deep into the wood fibres. That process backs a 15-year anti-rot guarantee with no retreatment needed. The glazing is 2mm styrene fully shatterproof and safer than conventional glass with excellent light transmission.

An automatic roof vent regulates temperature even when you are not around. Two removable shelves are included. You can realistically grow tomatoes, peppers, herbs and seedlings. The door fits left or right-hand opening and is latched for easy access.

This lean-to suits anyone with limited outdoor space who wants a proper timber greenhouse. Solid back panel construction means it can go against a wall or fence. Fixings and instructions are included for self-assembly.

The frame uses 12mm tongue and groove PEFC-certified timber with a smooth-planed finish. Pressure treatment is a five-stage process vacuum extraction of air from timber cells, flooding with preservative under vacuum, hydraulic pressure forcing preservative deep into the wood, a second vacuum to remove excess and a final low-pressure drying stage. This gives deep protection against rot and fungal decay. The 2mm styrene glazing is shatterproof and transmits light well. The apex lean-to roof pitch sheds rain effectively. One automatic heat-sensitive vent in the roof regulates temperature without manual input. The solid back panel braces the structure against wind loading.

The frame is PEFC-certified pressure treated timber with 12mm tongue and groove cladding and a smooth-planed finish. The glazing is 2mm styrene shatterproof and with excellent light transmission. The roof covering combines a timber frame with styrene panels. No glass is used anywhere in this greenhouse.

No base is supplied. You must prepare a firm level surface before assembly a concrete slab or level paving slabs are the most suitable options. No flooring is included. Ground preparation is entirely the buyer's responsibility before the greenhouse is erected.

This is a self-assembly flat-pack product. Forest describe construction as quick and easy. All fixings and instructions are included. Two people are advisable to hold panels in position during assembly. The packaged weight is 51.48kg so plan for two people to handle delivery and build. No professional installation is included though installation is available as a paid option from the merchant.

The base footprint is 1.04m x 0.44m. On the floor you can fit one standard grow bag end-on or two to three pot-grown tomato or pepper plants. The two removable shelves add usable growing space above floor level ideal for seed trays and small herb pots in spring. In summer use the floor for tomatoes or cucumbers and the shelves for peppers and basil. In autumn and winter the shelves work well for overwintering tender fuchsias, geraniums and young plug plants. Realistic capacity is around four to six tomato plants or two grow bags across floor and shelf space combined.

The pressure treatment means no annual retreatment of the timber is needed. Clean the styrene glazing with a soft cloth and mild soapy water to maintain light transmission. Check the automatic vent mechanism each spring to make sure it opens and closes freely. The 15-year anti-rot guarantee covers the timber without retreatment.

The base footprint is just 1.04m wide and 0.44m deep one of the smallest standalone greenhouse footprints available. It is designed to sit against a wall or fence using the solid back panel. Allow around 600mm clearance in front to open the door fully. The lean-to profile uses vertical wall space rather than garden floor area. Despite the small footprint the two shelves and floor space give a practical growing area well above what the external dimensions suggest.
