Amateur lookign for advice on the base!

Hello

I'd be extremely grateful if anyone could give me some advice! I'm just building a small greenhouse in my garden (6x4) and looking to site it beside a fence where the paving slabs are very much on a slope.


I'm looking to base the greenhouse on some sleepers, but am really unsure as to the best way to do this... My options seem to be...

a) Lift the slabs, and 'level' the ground somehow, then put the sleepers on top of the level ground.

b) Find some way to get the sleepers level (by playing about with bricks and stones until they're the right height) then concrete underneath them so that they're steady? I know how it's shown in the picture is not the way to do it, that's just laid out so I can check the crude measurements).

I'm sure to someone more experienced there's a really obvious solution! Many thanks in advance.

 

My greenhouse has a slope, purposely, a concrete slab was laid, so when I water excess drains out. I can`t make out what the incline depth is, then a row of breeze bolcks with scaffolding planks on top to give more height, bonus of a useful shelf inside from planks.

 

I would be inclined to lift the slabs, rake the soil level then place the greenhouse. May I ask, why are you using sleepers when the greenhouse has an integral base?

 

Hi folks. Slight change of plan I think.. keen to use the sleepers as I wanted a little extra height, and because I had them handy!

As suggested I've lifted the slabs, and am considering digging the sleepers into the ground somewhat, and mounting onto them. Any suggestions on how to get the ground completely level very much appreciated! I assume i need to rake and then lay the sleepers, giving them a few days to settle before fixing on the greenhouse?
