Janssens Pyramide Orangery Greenhouses
About Our Janssens Pyramide Orangery Greenhouses
The Janssens Pyramide Orangery combines Belgian engineering excellence with striking contemporary design. This isn't just a greenhouse—it's a luxury garden room built for year-round use. The distinctive pyramid roof floods your space with 360° natural light while creating an impressive architectural statement.
Each model features a heavy-duty box-section aluminium frame that provides exceptional strength without compromising on elegance. The 4mm toughened safety glass panels are secured using a superior rubber-gasket seal system (no clips required), creating a weatherproof seal that withstands our unpredictable British climate. You'll find integrated gutters and 40mm downpipes as standard, channelling rainwater efficiently away from your base.
Available in two generous sizes—10x10 and 12x12—and finished in your choice of Green or Black powder-coat, each Pyramide arrives with three hinged side vents for optimum airflow and a wide double sliding door that's perfect for moving furniture or large plants. Browse our Orangery Greenhouses collection to see how this range compares with traditional T-shape designs.
Every Pyramide Orangery is backed by a 13-year manufacturer's warranty and includes free UK mainland delivery. Professional installation is available across most of England, Scotland, and Wales—just call us on 0800 098 8877 to check your postcode area.

Choosing Your Janssens Pyramide Orangery Greenhouse
Size Selection: 10x10 vs 12x12
The 10x10 Pyramide (approximately 3m x 3m) provides 9 square metres of flexible space—enough for substantial greenhouse staging, seating for four, or a productive mix of both. Prices start from £7,399.
Step up to the 12x12 model (approximately 3.6m x 3.6m) and you gain 13 square metres—a 44% increase in floor area. This premium option (from £9,050) gives you room for formal dining furniture, multiple planting zones, or a dedicated workspace with abundant natural light.
Frame Colour: Green or Black
Your choice of powder-coat finish affects both aesthetics and garden integration. Green frames blend naturally with traditional planting schemes and cottage gardens. Black creates a bold, modern contrast that photographs beautifully against stonework or contemporary landscaping. Both finishes are UV-stable and won't fade or flake for decades.
Foundation & Installation Requirements
- Perfectly flat (within 5mm tolerance across the entire footprint)
- Completely level in all directions
- Solid and stable (poured concrete or mortared paving slabs are recommended)
- Minimum dimensions as specified for your chosen size
The included base plinth sits directly on this prepared surface. We provide comprehensive assembly guides and videos, but due to the Pyramide's size and precision, professional installation is the sensible choice for most customers.
Our Greenhouse Installation Service covers most of England, Scotland, and Wales, and our installers are factory-trained on these Belgian-made structures. Call us on 0800 098 8877 to check availability for your postcode and receive a quote.
How to Use Your Pyramide Orangery
As a Premium Greenhouse
The pyramid design offers significant advantages for serious gardeners. The tall central peak (over 2.5m) accommodates climbing tomatoes, passion fruit vines, and trained citrus trees. Superior light penetration from all angles reduces the need for plant rotation, while the three strategically-placed vents create cross-ventilation that prevents fungal issues. Add greenhouse accessories like automatic vent openers and shading for hands-off climate control.
As a Garden Room
This is where the Pyramide truly excels. The weatherproof construction and toughened glass make it a genuine second living space. Customers use theirs for:
- Alfresco dining with panoramic garden views
- Art studios flooded with consistent natural light
- Reading rooms and meditation spaces
- Home offices with an inspiring atmosphere
- Protected seating for entertaining guests year-round

Frequently Asked Questions about Janssens Pyramide Orangery Greenhouses
-
Do I need planning permission for a Pyramide Orangery?
Most UK homeowners won't need planning permission under Permitted Development rights if the structure is under 2.5m in height and more than 2m from any boundary. However, the Pyramide's central peak exceeds 2.5m, so check with your local planning authority before purchasing.
-
What is the difference between the 10x10 and 12x12 models?
Beyond the 44% increase in floor area, the 12x12 offers proportionally more headroom thanks to the pyramid geometry. Both models share identical construction, ventilation setup, and door width.
-
Can I arrange professional installation?
Yes. Installation is available across most UK postcodes and typically takes 1-2 days depending on model size. Call 0800 098 8877 for a quote.
-
What warranty covers the Pyramide Orangery?
Janssens provides a 13-year manufacturer's warranty covering structural defects in materials and workmanship.
-
How does the pyramid shape perform in high winds?
The aerodynamic pyramid design improves wind resistance, tested up to 100 km/h. The box-section aluminium frame and rubber-gasket glazing system prevent rattling and glass loosening.
