Janssens Mur Dwarf Wall Greenhouses

About Our Janssens Mur Dwarf Wall Greenhouses

The Janssens Mur Dwarf Wall Greenhouses combine Victorian elegance with Belgian engineering precision to create one of the strongest dwarf wall greenhouse ranges available in the UK. Handcrafted in Belgium since 1946, these premium structures feature box-section aluminium frames that deliver 40% better wind resistance compared to standard tubular frames. Each greenhouse sits on your brick or stone dwarf wall foundation, creating superior heat retention and a traditional aesthetic that complements any garden.

Available in 7ft, 10ft, and 12ft wide models, the Mur range offers exceptional growing space with generous 2m eaves height. All models come with premium features as standard:

• 4mm Toughened Safety Glass: 6 times stronger than standard horticultural glass.
• Full-Length Rubber Gaskets: Provides a weather-tight, professional-grade seal.
• Powder-Coated Finishes: Choose from heritage green or contemporary black.
• Victorian Roof Crestings: For an authentic, elegant aesthetic.
• Integrated Gutters & 40mm Downpipes: Robust water management.
• Stainless Steel Fittings: Resists corrosion for 25+ years.

Free UK mainland delivery and a 13-year frame warranty demonstrate why serious gardeners choose Janssens Greenhouses for long-term growing success.

Why Choose a Janssens Mur Dwarf Wall?

Aluminium Frame vs. Wooden Frame

Aluminium requires zero maintenance—no painting, staining, or treating every 2-3 years as timber frames demand. The box-section frame provides 3 times better structural rigidity than standard glazing bar systems, making these greenhouses ideal for exposed or windy sites.

The Benefit of the Dwarf Wall Foundation

• Superior Heat Retention: The wall acts as a "thermal mass," absorbing daytime heat and releasing it overnight.
• Lower Heating Costs: This thermal efficiency can reduce heating costs by approximately 30%.
• Improved Drainage: The raised base prevents ground moisture from reaching plants.
• Comfortable Working Height: The wall creates a raised interior that reduces back strain.

Need Help with Assembly? A professional greenhouse installation service is available for the aluminium frame once your dwarf wall is complete.

Choosing Your Janssens Mur Dwarf Wall Greenhouse

The 7ft Wide Models (Compact Gardens)

These models work beautifully in compact gardens or courtyard settings, providing 49-77 square feet of growing area. They fit neatly alongside boundaries while still offering full walking access and space for greenhouse staging on one side.

The 10ft Wide Models (The All-Rounder)

This range represents the sweet spot for most gardeners. It's wide enough for staging on both sides with a central 2ft path, yet manageable for one person to maintain. Popular models like the 10x15ft deliver 150-190 square feet, sufficient for seasonal vegetable production and year-round propagation.

The 12ft Wide Models (Serious Growers)

For serious growing or commercial applications, the 12ft wide models provide professional-grade space. The flagship 12x19ft model offers 228 square feet—comparable to a small polytunnel but with far superior appearance and durability. These larger greenhouses include double locking doors for secure access.

Price & Compatible Accessories

Prices for Janssens Mur greenhouses start from £4,699, rising to approximately £8,500 for the largest 12x19ft specification. Each Mur greenhouse product page displays only compatible staging, shelving, and ventilation options, removing any guesswork.

Frequently Asked Questions

• What is a dwarf wall greenhouse and why choose one?

  A dwarf wall greenhouse sits on a low brick or stone wall (2-3 courses high). The wall absorbs heat during the day and releases it at night, maintaining temperatures 5–7°C warmer than glass-to-ground models and reducing heating costs by 30%.

• How much do Janssens Mur greenhouses cost?

  Prices range from £4,699 for the 7x7ft model up to £8,500 for the 12x19ft. All include free UK delivery and a 13-year warranty.

• Do I need planning permission for a dwarf wall greenhouse?

  Most do not, as long as the total height remains below 2.5m when placed within 2m of a boundary. Always confirm with your local planning authority.

• What's the difference between green and black powder coating?

  Both finishes offer identical durability. Green suits traditional gardens, while black creates a bold, contemporary look.
