Mini Lean to Greenhouses with Backs

About Our Mini Lean-To Greenhouses With Backs

Our mini lean-to greenhouses with backs solve a common garden challenge—you don't need a house wall to create a productive growing space. These compact structures are designed to be used with an optional glazed back panel, so you can place them against a fence, shed, or even use them freestanding on your patio.

Starting from £320, each model is built with a premium aluminium frame that won't rust or rot, and comes with toughened glass glazing for superior insulation and light transmission.

Available in 2ft and 3ft widths, these greenhouses pack impressive features into a small footprint. You'll get built-in gutters to collect rainwater, a single sliding door for easy access, and adjustable seed tray shelves to maximise your growing capacity. Browse our mini greenhouses range to compare sizes, or explore our full selection of small lean-to greenhouses if you need slightly more space. Every model includes free UK delivery and a 25-year warranty on the frame.

Choosing Your Mini Lean-To Greenhouse

The main decision is width. A 2ft model fits tight spaces like balconies or the gap between your house and fence, perfect for herbs and seedlings. The 3ft version doubles your growing area and accommodates standard-width staging if you want to add shelving later.

The key feature of this collection is the optional glazed back panel. Adding this panel is what allows you to use the greenhouse freestanding or against any vertical surface—you're not limited to house walls like traditional, open-backed lean-tos.

Glazing thickness matters for your climate. The 3mm toughened glass provides excellent clarity and adequate insulation for most UK gardens. Upgrade to 4mm if your site is exposed to strong winds or you want maximum heat retention. Prices range from £320 for a basic 2ft model and reach £1599 for a large 3ft version with premium glazing and colour options. Before you buy, check our greenhouse base preparation guide to ensure you have a level foundation, or book our professional installation service and we'll handle everything.

Where to Use a Mini Lean-To With a Back

These versatile structures adapt to challenging garden layouts:

• Place one against fence panels to create a productive growing strip.
• Position it on a balcony or small patio where a traditional lean-to isn't possible.
• Use it freestanding as a vertical garden feature.
• Tuck it into narrow side passages or awkward corners.

The built-in gutters make fence placement especially practical—you can direct collected rainwater into a storage butt without roof runoff splashing onto your fencing.

Frequently Asked Questions

• What is a mini lean-to greenhouse with a back?

  It's a compact, aluminium lean-to greenhouse that can be fitted with an optional glazed back panel. This panel makes the structure self-supporting, so you don't need a house wall. You can place it against any surface like fences or sheds, or use it completely freestanding on your patio.

• Can I use a lean-to greenhouse against a fence?

  Yes, this is exactly what they are designed for. When you add the optional glazed back panel, the greenhouse becomes a freestanding unit. It rests against the fence but doesn't need to be fixed to it for support, making it perfect for wooden or panel fencing.

• Does a mini lean-to with a back need a solid wall?

  No, and that's the key advantage. Unlike traditional open-backed lean-tos, adding the glazed back panel makes these structures self-supporting. You can position them anywhere you have a flat, stable surface. Read our greenhouse buyers guide for detailed placement advice.

• How much do mini lean-to greenhouses with backs cost?

  Prices start from £320 for a 2ft wide model with 3mm toughened glass. The optional glazed back panel typically adds £80-£120 to the base price. A top-end 3ft version with 4mm glass and a colour finish can reach £1599. All prices include free UK mainland delivery.

• How do I add the glazed back panel and other accessories?

  We make this simple. On each greenhouse product page, we list all compatible accessories—including the glazed back panel, staging, and automatic vent openers. You can select everything you need in one place, ensuring it's perfectly tailored to your chosen greenhouse model before you add it to your basket.
