Who this guide is for
- Gardeners planning a greenhouse purchase
- People weighing frame and glazing against budget
- Anyone deciding how large a greenhouse to build
- Owners preparing to brief an installer
Frame and glazing
The frame material and the glazing type are core cost levers. Frames range in durability and look, while glazing varies from glass to lighter alternatives. Together they shape much of the greenhouse's character and budget.
- Frame material and durability
- Glazing type and quality
- How frame and glazing affect look and budget
Size and base
A larger greenhouse needs more material and a more substantial base. The base, paved, concrete or proprietary, is part of the budget and depends on ground conditions, which can add cost on harder sites.
- Greenhouse size and footprint
- Base type and ground conditions
- Site access for materials
Services and accessories
Any electrics, water or heating add cost and require professional work, while accessories like staging, vents and shading also contribute. The more equipped the greenhouse, the more these extras weigh on the budget.
Siting and the longer view
Where a greenhouse sits affects how well it performs and how easy services are to provide, which has budget implications. Thinking about siting and ongoing upkeep gives a more honest view than the headline cost of the structure.
- Siting affects performance and services
- Consider ongoing upkeep
- Look beyond the headline structure cost

Frequently asked questions
Questions readers ask about this topic
What drives greenhouse cost most?
Frame and glazing are core levers, along with size, the base and any services. A larger greenhouse needs more material and a more substantial base, and equipped greenhouses cost more. This page gives no figures.
Is the base part of the cost?
Yes. A greenhouse needs a sound base, and its type, paved, concrete or proprietary, plus the ground conditions, all contribute to the budget. Harder sites can add cost, so the base should not be overlooked.
Do I need to budget for services?
If you want electrics, water or heating, then yes, and that is professional work. Factor services into the picture and keep the actual work with the relevant qualified trades rather than treating it as optional.
How do I keep the budget realistic?
Start from the levers, frame, glazing, size, base, services and accessories, and prioritise by how you will use the greenhouse. Understanding which choices push the budget helps you specify to your goals.
