    Frequently Asked Questions

    • What base would be best for my Greenhouse?

      For your greenhouse to thrive, it needs a solid foundation. Here are our top picks:

      Paving Slabs: A classic choice! They're easy to lay and provide excellent drainage.

      Concrete Base: Want something ultra-sturdy? A concrete base is your go-to option. It's long-lasting and provides a super-level surface.

      Decking: Yes, you can use decking! Just make sure it's robust and as flat as a pancake.

      Remember, a great base sets the stage for years of happy gardening. So take your time and get it right - your future plants will thank you!

    • How is the greenhouse packaged?

      The Frame and Base: Imagine long, slim parcels (shoe boxes, but longer) - that's how your greenhouse frame and base will arrive. We pack them snugly in sturdy cardboard boxes to keep everything safe and sound during their journey to you.

      Now, this depends on what type you've chosen:

      • Ordered horticultural glass? It'll come neatly boxed up.
      • Opted for full pane toughened glass? Each sheet will arrive individually wrapped for extra protection.

      We take extra care to ensure every piece of your green haven reaches you in perfect condition. It's like a jigsaw puzzle waiting to be put together!
