Hexagonal Greenhouses

About Our Hexagonal Greenhouses

Looking for a greenhouse that's both practical and visually striking? Hexagonal greenhouses offer a unique 6-sided design that creates an elegant garden focal point while delivering excellent growing conditions. These distinctive structures are naturally more wind-resistant than traditional rectangular models, making them ideal for exposed gardens or corner plots where space is at a premium.

Our collection features premium models from leading manufacturers. The Vitavia Hera Hexagonal Greenhouse range includes options with silver anodised or powder-coated aluminium frames in green and black finishes. You'll find choices between 3mm horticultural glass or toughened safety glass, with built-in gutters, sliding doors, and side louvre vents. All Vitavia models include a 12-year warranty and range from 4500 models (approximately 6x6ft) up to 9000 models (approximately 8x8ft).

The Palram Canopia Oasis 8ft Hexagonal Greenhouse offers a more contemporary approach with its grey powder-coated aluminium frame, 4mm twin-wall polycarbonate roof, and clear single polycarbonate sides. This model features a locking hinged door, side louvre vent, and comes with a 5-year warranty.

What makes hexagonal greenhouses particularly appealing is their pavilion-style aesthetic. Many customers use them as dual-purpose spaces – growing areas that double as attractive garden sunrooms. The 6-sided structure distributes wind pressure more evenly than rectangular designs, reducing the risk of panel damage during storms. Free UK delivery is included on all models.

Choosing Hexagonal Greenhouses: Quick Guide

• Size Considerations: Small hexagonal greenhouses start around 6x6ft (Vitavia Hera 4500), perfect for compact gardens or patios. The larger 8ft models provide approximately 40% more growing space and comfortable headroom for taller plants.
• Price Range: Entry-level models start from £1,500–£2,000. Mid-range glass models cost £2,000–£3,000, while premium toughened glass designs reach £3,000–£4,500.
• Foundation Planning: A 6-sided base requires precision. See our guides on how to build a concrete base or paving slab bases. Professional installation ensures the best results.
• Quality Indicators: Look for powder-coated aluminium frames, toughened glass, built-in gutter systems, and 10–12 year warranties.

Frequently Asked Questions

• How much do hexagonal greenhouses cost?

  Hexagonal greenhouses range from £1,500 for small polycarbonate models to £4,500+ for large 8ft toughened glass designs. Most customers choose mid-range glass models between £2,000–£3,000. Free UK delivery is included on all models.

• What are the benefits of a 6-sided greenhouse design?

  The hexagonal shape offers superior wind resistance by distributing pressure evenly across all sides, making it ideal for exposed gardens. It also maximises use of corner spaces and provides a visually appealing pavilion-style feature.

• Are hexagonal greenhouses difficult to assemble?

  The main challenge is creating a precise 6-sided base, but the frame assembly is straightforward. Professional installation is available and recommended for best results.

• Which is better for a hexagonal greenhouse: glass or polycarbonate?

  Toughened glass or horticultural glass is ideal for hexagonal greenhouses due to strong wind loading angles. Polycarbonate roofs are good for insulation, but side panels should be glass for clarity and stability.

• How do I layout shelving in a hexagonal greenhouse?

  The best layout is a horseshoe-shaped benching system along three sides, leaving clear access by the door. Larger 8ft models benefit from central staging with 360° access.

• Do hexagonal greenhouses need more maintenance than rectangular ones?

  No — maintenance depends on material, not shape. Aluminium hexagonal greenhouses require minimal upkeep beyond occasional cleaning and seal checks. Powder-coated finishes prevent rust for decades.
