Potting sheds are another option or an alternative to a standard greenhouse. They combine storage and growing space in one structure and usually cost between £700 and £1,500, depending on layout and materials.
Framing and glazing materials
Framing and glazing choices have a big impact on both price and durability.
For the frame:
- Aluminium is lightweight and resistant to rust, sitting in the mid-price range.
- Steel is strong and long-lasting but usually costs more.
- Wood offers a traditional look, with prices varying depending on the type and finish.
For glazing:
- Glass gives clear visibility and long-term durability but costs more.
- Polycarbonate is lighter, safer, and often more affordable.
- Polyethylene film is the cheapest option, though it needs replacing more often.
Material choices affect upfront cost as well as long-term maintenance.
Customisations
Extras can improve how your greenhouse works, but they do add to the price. Shelving can cost £50 to £200, but you can get a unit for as low as £10 if you know where to look. And let’s not forget ventilation upgrades, which can add £30 to £150.
Round-up
Greenhouse costs depend mainly on:
- the size you choose
- the style you prefer
- the materials used
Extras and custom features can improve usability, but they do increase the price. Having a clear budget from the start helps you focus on what matters most.
