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.
Price: from £869

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.
