Description

Robinsons Lean‑To Greenhouse – 8’4″ Wide

The Robinsons Lean‑To is a beautifully engineered wall‑mounted greenhouse designed to bring professional‑grade growing conditions to patios, courtyards and smaller gardens. Its refined, lower‑pitch roofline creates a reduced ridge height ideal for properties with height restrictions, while still delivering excellent light transmission and a bright, airy interior. The structure is finished with Robinsons’ signature extra‑strong box‑section aluminium frame, offering outstanding rigidity and long‑term durability.

Screw‑in PVC glazing capping secures the 4mm toughened safety glass cleanly and securely, providing superior wind resistance and a crisp, refined finish. Practical features come as standard, including an automatic roof vent, a louvre side vent, Victorian‑style guttering, a lockable sliding door, and a low‑threshold entrance for easy access. Stainless‑steel fixings, kick panels and neatly finished cappings reflect the meticulous build quality that sets Robinsons apart.

Available in a range of lengths and heritage colours, the Lean‑To can be tailored to suit both traditional and contemporary homes. Its wall‑mounted design captures and retains warmth efficiently, making it ideal for overwintering tender plants, propagating young seedlings or creating a sheltered, productive growing space right outside the back door.

The Robinsons Lean‑To is a compact yet exceptionally strong greenhouse for gardeners who want premium engineering, elegant styling and a structure that integrates seamlessly with the architecture of the home.

Installation & Base

Installation services are available via Bourne Buildings in some locations

Robinsons greenhouses need to be placed on a flat, level, compact (firm) base, with paving slabs or concrete being the best options.  The base should be the same size as the building itself*, level (with no drainage slope) with 2 inches above ground level to avoid surface water running underneath.

Robinsons Greenhouses can sit on either a solid paving or concrete base as described above, or on concrete strip footing. Dwarf wall models will require a suitable dwarf wall to be constructed – Exact measurements will be supplied once you have placed an order.

Clearance – We recommend at least 18” clearance all round for installation, airflow, and future maintenance. Victorian models: Please allow 24” clearance all round. Please speak with a staff member if you have less clearance.

*Bases can be larger than the building if required by the customer but must not be any smaller.

*All sizes are approximate *
