Selecting Your National Garden Scheme Greenhouse

Now, with multiple National Garden Scheme greenhouses to pick from, how do you know which one will work for you? 

Don’t worry! We’ll discuss all relevant information with you at the outset. Together, we’ll discover the ideal Victorian greenhouse solution.

We will consider the following:

  • Garden size
  • Orientation
  • Distance from fences, so they don’t block the light
  • Planning permission
  • Positioning the widest part of the greenhouse to face South or placing it against a wall to benefit from the heat

We’ll assist with all these considerations. Let’s help you make the best, long-term decision for your plants.

What Will My National Garden Scheme Greenhouse Cost?

National Garden Scheme greenhouses have set designs and set prices for all customers in Mainland England and Wales. When you order a glasshouse for these areas, we will donate 5% of the list price to the National Garden Scheme.

For any location outside Mainland England and Wales, you can request a quote. The delivery address will determine the final cost. 

Our National Garden Scheme prices refer to the glazed structures only. We can provide you with a quote for additional accessories, and can usually recommend local builders to carry out the brick bases and building work.
