Hexagonal Greenhouses

A hexagonal greenhouse handles wind better than any rectangular model we sell. The six-sided frame spreads pressure evenly across every panel, so these hold up well in exposed gardens and corner plots. We stock aluminium-framed models from Vitavia and Palram Canopia in glass or polycarbonate glazing.

Prices range from £729 for the Vitavia Hera 4500 to £1,759 for the larger Hera 9000 in toughened glass. All models include integrated gutters and louvre vents as standard, with Free UK Mainland Delivery.

About Our Hexagonal Greenhouses

We stock 5 hexagonal greenhouses, all in stock and ready to ship, with prices from £729. A hexagonal greenhouse is a six-sided feature for the garden. The shape pulls light in from every angle and gives you central staging access without reaching over a bench. It earns its place as much for how it looks as for what you grow. We pair it well with a Victorian greenhouse on a formal plot.

The compact footprint suits a patio corner or the centre of a lawn. When we fit these, we treat them as a statement piece first. A smaller model rivals the growing room of a small greenhouse while looking far more like a folly. Fit corner shelving from our greenhouse staging range to use the angled walls.

Why We Chose This Range

"I picked the Vitavia Hera because the six-sided frame is built differently to a square model. The corner braces are reinforced and the extrusions are thicker. We had Hera 4500s standing through Storm Eunice on a coastal plot with no panel losses. People buy hexagonal for the look. They keep them because they work."

Matt, Founder of Greenhouse Stores

💡 Tip: Measure your site diagonally, corner to opposite corner, before you order. If any diagonal differs by more than 10 mm, the doors will bind and the glass will not seat. A 4ft spirit level is the least you need.

🔧 Matt's Installation Tip: Build a six-sided base

The biggest mistake we see is a round concrete pad under a six-sided frame. It will not sit right. You need a base that matches the footprint exactly. We lay 50 mm paving slabs on a 50 mm sand bed, set to the plinth template that ships with every model. Peg the base out and check all six corners before you commit.

Matt's Pick: Vitavia Hera 4500 Silver, Toughened Glass

Best For: exposed or windy gardens that need a feature greenhouse.

Why I Recommend It: the toughened glass shrugs off wind better than horticultural glass, and the 4.5 m² footprint fits most plots. It is the size we install most.

Frequently Asked Questions

  • How much does a hexagonal greenhouse cost?

    Hexagonal greenhouses here range from £729 to £1,759. The Vitavia Hera 4500 starts the range in horticultural glass. The larger Hera 9000 sits at the top in toughened glass. All include free UK mainland delivery.

  • What size hexagonal greenhouse do I need?

    The Hera 4500 at 4.5 m² suits most gardeners. It holds roughly 15 to 20 medium pots with staging fitted. Step up to the Hera 9000 at 9.0 m² if you want space to grow and sit.

  • Are hexagonal greenhouses more wind resistant?

    Yes, the six-sided frame spreads wind load across more panels. This eases pressure on any single pane. The Hera uses reinforced corner braces. For exposed sites, choose toughened glass.

  • What base does a hexagonal greenhouse need?

    A level six-sided base that matches the footprint exactly. Paving slabs on compacted sand work well. Avoid round concrete pads. Level all six sides to within 5 mm or the doors will bind.

  • Can I use a hexagonal greenhouse as a garden room?

    Yes, many customers use the Hera this way. The eaves height gives comfortable standing room. The Hera 9000 fits a small table and two chairs alongside plants.
