Available in 7ft or 10ft widths with choice of 271cm or 341cm ridge heights, these greenhouses suit bungalows and two-storey homes. Every model includes integrated guttering, double sliding doors, and 2 automatic roof vents as standard. Free UK mainland delivery and professional installation service available.

Key features of the arcadia mur plus collection

Why choose a dwarf wall (mur) lean to greenhouse?

A dwarf wall lean-to greenhouse sits on a brick or block wall built to approximately 60-75cm height. This makes a permanent garden room rather than a temporary structure. The brickwork acts as thermal mass, absorbing daytime heat and releasing it overnight, which reduces temperature fluctuations by 40-50% compared to fully glazed models. This design suits UK climates perfectly for year-round growing.

The permanent foundation integrates with your home's architecture. You can build raised beds directly onto the internal floor, eliminating bending and creating accessible growing at waist height. All Janssens Greenhouses use this professional installation approach for structures designed to last 25-30 years.

Choosing your janssens arcadia mur plus lean to greenhouse

Size selection

The 7x15 Janssens Arcadia Plus Mur Lean To (2.15m × 4.6m) provides 10m² growing space, suitable for 12-15 tomato plants or mixed vegetable rotation. The 10x20 Janssens Arcadia Plus Mur Lean To (3.06m × 6.14m) offers 18.8m² for serious cultivation or creating a garden room environment. Consider your wall length and check planning requirements for structures exceeding 15m² floor area.

Ridge height matters

Choose 271cm ridge height for bungalows or single-storey extensions. The 341cm option suits two-storey walls, positioning the greenhouse below first-floor windows. This affects internal headroom: taller models give 2.2m standing height at the wall.

Investment & installation

Prices start from £5,999 for compact models, reaching £8,750 for premium 10ft × 20ft configurations. These are made-to-order structures with 8-12 week lead times. Base preparation requires building a dwarf wall to 60-75cm height, our Greenhouse Installation Service includes this work. Read our How to Build a Greenhouse Base guide for DIY foundation planning.

Frequently asked questions about janssens arcadia mur plus lean to greenhouses

• What makes the Arcadia Mur Plus different from standard lean-to greenhouses?

  The Mur Plus mounts to a purpose-built dwarf wall (60-75cm high brick structure) rather than sitting on a full base frame. This creates superior thermal performance, with the brickwork storing heat and reducing overnight temperature drops by 3-5°C. The dwarf wall design allows raised bed cultivation at comfortable working height and provides a more permanent, integrated appearance with your home's architecture.

• How much does a Janssens Arcadia Mur Plus cost?

  Prices range from £5,999 for the 7x10 model to £8,750 for the largest 10x20 configuration. This includes the complete aluminium and glass structure with 13-year warranty, built-in guttering, automatic vents, and free UK mainland delivery. The price does not include dwarf wall construction (typically £400–£800 depending on length) or base preparation. Our Greenhouse Installation Service provides complete turnkey installation including all groundwork.

• Do I need planning permission for an Arcadia Mur Plus lean-to?

  Most domestic lean-to greenhouses are permitted development in England and Wales if they don't exceed 4m height and cover less than 50% of the garden area. The Arcadia Mur Plus ridge heights (271cm or 341cm) fall within limits. However, conservation areas, listed buildings, and flats require planning permission. Always check with your local authority planning department before ordering, as regulations vary by region and property type.

• Can I install the greenhouse myself or do I need professionals?

  Janssens supplies full assembly instructions, and competent DIYers with two people can install the structure over 3-4 days. However, you must first build the dwarf wall foundation to precise specifications (level within 3mm, square corners, correct height). Most customers use our professional installation service for the complete project including brickwork, base, and greenhouse assembly. This ensures correct mounting, proper sealing, and maintains warranty validity.

• What ridge height should I choose for my property?

  Choose the 271cm ridge height for bungalows, single-storey extensions, or where you want the greenhouse to finish below ground-floor window sills. Select 341cm for two-storey homes where you want the structure to extend higher up the wall, typically finishing below first-floor windows. The taller option provides better internal headroom (2.2m vs 1.9m at the wall side) and creates more impressive visual impact.

• How do I add accessories like staging or extra vents?

  Browse compatible accessories on each individual product page before adding to your basket. We list only items that fit your specific Janssens Arcadia Mur Plus model, from aluminium staging and shelf systems to additional roof vents and rainwater collection kits. This ensures perfect compatibility. We've been official Janssens stockists for 15+ years and know exactly which accessories work with each greenhouse configuration. Add everything in one transaction for coordinated delivery.

• What frame colours are available?

  The Arcadia Mur Plus comes in three professional powder-coated finishes: Racing Green (RAL 6005), Matt Black (RAL 9005), and Mill Finish White. All colours use the same box-section aluminium construction and carry the full 13-year warranty. Colour is specified at order and cannot be changed after manufacture begins.
