A wall mounted mini greenhouse is the ultimate vertical growing solution for gardeners with limited floor space. By attaching directly to a masonry wall, these structures utilize thermal mass—absorbing heat from your home during the day and releasing it at night to protect delicate seedlings. Engineered with rust-proof aluminium and 4mm toughened safety glass, they transform bare walls into productive hubs for herbs, salads, and over-wintering tender perennials.
Discover the perfect growing solution for compact gardens with our collection of Wall Mounted Mini Greenhouses. Designed to maximise limited space, these structures transform bare walls, balconies, and narrow patios into productive growing environments. Unlike traditional freestanding models, a wall mounted mini greenhouse utilises the thermal mass of your property, absorbing heat during the day and releasing it at night to protect your plants from frost.
Our range features industry-leading brands like Access and Vitavia, offering durable aluminium wall greenhouses that withstand the British weather. Whether you need a model that hangs directly on the wall or a "lean-to" style that stands against it, you’ll find options with toughened safety glass for clarity or twin-wall polycarbonate for added insulation. With Free UK Delivery and a 20 Year Elite Warranty on selected models, you can start your vertical garden with complete confidence.

Why We Chose This Range
“We curating the Wall Mounted Mini Greenhouse range specifically for urban balcony gardeners. Most mini models struggle with stability in high-rise winds, but these units bolt directly to the building, making them the most wind-resistant structures we sell. We specifically chose the Access Westminster and Elite Window Garden models for their internal bracing—where other manufacturers cut corners, these brands ensure the frame won't bow under the weight of saturated compost trays.”
— Matt, Founder of Greenhouse StoresSelecting the right Wall Mounted Mini Greenhouse depends on your available space and growing goals. If you have zero floor space, such as on a balcony, consider a "hanging" model like the Access Wall Garden. These bolt directly to the masonry, keeping the floor clear. For patios where you can spare a small footprint, our Mini Lean To Greenhouses With Backs offer deeper growing space for taller crops like tomatoes and peppers.
The best choice for light transmission and wind resistance. It is heavy and durable, making it ideal for windy locations where stability is key.
Lightweight and shatterproof, making it a safe option for family gardens with children or pets, though slightly less clear than glass.
Prices typically start from £150 for basic polycarbonate lean-tos, ranging up to £900+ for premium architectural glass models. Don't forget to maximise your space with Greenhouse Staging to organise your pots and trays efficiently.
Wall mounted greenhouses carry significant weight once fully staged. The standard plastic wall plugs found in many hardware kits aren't enough for long-term safety. I always recommend using M6 masonry expansion bolts or chemical anchors if you are fixing into older, softer brickwork.
Crucially, ensure you use a spirit level on the wall-plate before drilling. If the top rail is even 2mm out of level, the sliding glass doors will bind or rattle in the wind. Read our full base and wall preparation guide here.
A wall mounted unit is typically bolted directly to the wall at any height, often keeping the floor clear. A lean-to sits on the ground and leans against the wall for support. Wall mounted units are superior for balconies, while lean-tos offer more height for tomatoes.
We do not recommend attaching heavy glass models to standard garden fencing. For safety, these require a solid masonry wall (brick, block, or stone) to support the weight of the frame and the glass panels.
Yes. This is called 'Thermal Mass'. The wall absorbs solar energy during the day and radiates heat back into the greenhouse at night, keeping temperatures up to 5°C warmer than a freestanding model.
Absolutely. They are excellent for salad leaves, herbs, peppers, and chillies. Larger 3x6 Mini Greenhouses provide enough vertical height for vine tomatoes and cucumbers.
Yes, specifically the toughened glass models. Because they are anchored securely to a solid masonry wall, they are often more wind-resistant than small freestanding greenhouses.
