Greenhouse advice

[Sim2500]

Hi,

I'm going to effect a greenhouse when it gets slightly warmer.

I did the initial ground work and noticed now that the ground is slightly uneven. What would happen if I built on it?

I should mention my greenhouse is small, its 6x6 but with toughened glass

A friend erected a greenhouse 4 meters square. He was a fraction low in a corner but not much. The glass does not fit as well as it should and lets rain in. He wishes he had been more careful now.

Here what we did for what it's worth. We are DIY duffers BTW. .

We put up a 2x3m secondhand one four? years ago. Ground hadn't been disturbed for many years and was compact gravel and ash (ex parking space) . Stripped off the thin layer of grass and leveled around the base to maybe +- 10mm, laid approx. 20mm layer of course sand/fine gravel and bedded concrete blocks into sand. Ended up level to about +-5mm.

Placed greenhouse on blocks.

I put up a 10' X 12' years ago.

The instructions said with the metal base it could be put directly on soil. Rubbish! I wasted so much time trying to get it level.

I ended up cutting some slabs into 6" strips, which I laid on sand/cement, which was so much easier to get level.

Hi Danny, resurrecting an old thread to ask about your greenhouse perimeter(?) base. We're just looking at getting a new one and want to plant into its borders with a middle path.

So how easy is it to 'attach' the greenhouses metal base to the slabs? I just got a quote from a landscaper and they advised against putting it on slabs as they might crack when they were drilled. He suggested pouring concrete. How did yours go?
