Orangery Greenhouses

About Our Orangery Greenhouses

Orangery greenhouses combine Victorian elegance with modern growing functionality, offering a unique dual-purpose structure that works as both a productive growing space and an attractive garden room. Unlike standard greenhouses, these architectural designs feature distinctive T-shaped or hexagonal profiles with high eaves reaching 2.2–2.5 metres, providing 30–40% more vertical growing capacity for climbing plants and tall specimens.

Our collection includes premium models from leading manufacturers including the Vitavia Sirius Orangery Greenhouse with its striking black powder-coated frame, the Janssens T-Shaped Orangery Greenhouse built with commercial-grade 4mm toughened glass, and elegant Vitavia Hera Hexagonal Greenhouses that create stunning garden focal points. Every orangery greenhouse ships with free UK mainland delivery, and most aluminium models come with 12–15 year manufacturer warranties.

The increased eaves height creates a comfortable environment for relaxing alongside your plants, with most models offering 15–30 square metres of floor space and enough headroom for standard furniture. Our orangery greenhouses feature 3–4mm toughened safety glass, powder-coated aluminium frames resistant to high winds, and integrated ventilation systems with automatic roof vents.

Choosing Orangery Greenhouses: Quick Guide

Selecting the right orangery greenhouse depends on three key factors: your available space, intended use balance between growing and leisure, and budget allocation. Most buyers choose structures between 8ft–12ft wide and 10ft–20ft long, providing adequate space for staging benches, seating areas, and central growing beds.

• Palram Canopia Orangery Greenhouses – £2,400–£3,200 with polycarbonate glazing
• Janssens Pyramide Orangery Greenhouses – £4,500–£6,800 mid-range aluminium models
• Janssens Kathedral Orangery Greenhouse or Elite TITAN 1000 Greenhouse – £8,000–£12,000 for premium installations

Aluminium frames require significantly less maintenance than timber alternatives and won’t rot or warp, making them ideal for complex orangery designs with valley roofs and multiple gables. Swallow T-Shaped Wooden Greenhouses offer traditional aesthetics with thermowood construction and 10-year warranties, though they need re-treating every few years to maintain their optimal look.

These architectural structures require perfectly level concrete or paving slab foundations. See our base guides:

Frequently Asked Questions

• How much do orangery greenhouses cost?

  Orangery greenhouses range from £2,400 for compact polycarbonate models to £12,000+ for premium glass structures. Most customers spend £5,000–£7,500 on mid-range aluminium designs with toughened glass and free UK delivery.

• Do I need planning permission for an orangery greenhouse?

  Usually not — orangery greenhouses fall under Permitted Development rights. Ensure the structure occupies under 50% of your garden and remains below 2.5m when within 2m of a boundary. Always check if your property is listed or in a conservation area.

• Can I use an orangery greenhouse year-round?

  Yes. With appropriate heating, orangery greenhouses maintain 5–10°C in winter. Add bubble wrap or thermal screens to improve insulation, and ensure automatic vents are functional to prevent overheating in summer.

• What's better for an orangery – aluminium or wooden frames?

  Aluminium suits 80% of installations thanks to its low maintenance and long lifespan (15+ years). Powder-coated aluminium doesn’t warp or rot. Wooden frames, such as Swallow Thermowood, provide warmth and period charm but require periodic re-treatment.

• How long does it take to install an orangery greenhouse?

  Professional installation takes 2–3 days for T-shaped orangeries and up to 6 days for large DIY assemblies. Allow 3–4 weeks from order to completion, including delivery and base checks.

• What heating costs should I expect for an orangery greenhouse?

  Expect £15–£30/month for a 10m² orangery maintained at 5°C during winter. Larger 20m² models may reach £55+. Adding insulation can reduce energy use by up to 35%.
