Laying Concrete Base for Greenhouse

Hi guys,

My gf's ordered a greenhouse online and is now bugging me to sort out a base for it so she can have it delivered and grow...... whatever grows over winter LOL.

She's also insisiting that a path must go to the greenhouse. She's planning on having some fancy slabs delivered and wants me to use them for both the path and the greenhouse to sit on.

I've laid plenty of slabs for paths in the past, but have always used sharp sand underneath.

I'm thinking that for something as large as a greenhouse a few cms of concrete underneath the slabs would be a safer option than just sharp sand.

I've never concreted such a large are before, but I'm presuming that it shouldn't be too problematic.

I was thinking of laying some bricks end-to-end to form a square, then just filling the resulting square with concrete, using a spirit level to ensure it's flat (the garden is on a slight slope), and then either popping the slabs on the top just before it dries, or letting the concrete dry and then adding a little bit of mortar on top of that before laying the slabs.

Does this all sound sensible, or is there anything really obvious, or important, that I've not thought of?

Grateful for any feedback whatsoever

Any thoughts, people?

I erected a Rhino greenhouse earlier this year - built like a tank, but with windows!

I took the option of simply levelling the soil, fortunately heavy clay, and according to the instructions I had to dig six holes, each about a foot deep and about the same diameter. Into each of these went a U-shaped anchor attached to the greenhouse base and they were then filled with Postcrete.

The greenhouse hasn't moved a mm, despite some high winds.
