Greenhouse straight onto the grass/soil?

[bradlo]

A little while ago I wrote that I have been given this greenhouse...and now the time for re erection is approaching.... as you can see from the pic it was erected straight onto the soil, and had been there for the past 15 years plus, with no problems.....
So...
I presume it will be perfectly OK to erect it onto soil/grass again in my garden...it stands on about a 5 inch aluminium plinth with stakes on each corner to drive into the earth.
I am a bit loathed to pit it on a concrete or block base, as there is a chance we may move house in the next few years and would like to "up stakes" with the greenhouse and take it with us !
Cheers!

Why don't you just pit the corner stakes into concrete. A few bags of postcrete would do the trick .Alternatively, Lay some concrete blocks on the soil and fix the base to the concrete bocks. If you decide to upstakes and move, simply unscrew from the concrete blocks

Thats how we fixed my greenhouse then inside I've got stone flag path part way down the centre.

Mine's on the soil with angle iron driven into the soil in the corners, and these are screwed to the g/house frame

That's how this one was fixed originally, and it seemed pretty stable to me ! I want to try to avoid concreting etc. if at all possible !

I sunk plant pots in the corners (where the spikes are - in the centre too) of mine, and put postcrete in them. If I move, and take it with me, i'll buy another base no doubt

That looks like a 12' x 8' to me if so the weight of glass should keep it fairly stable. Providing the soil is fairly compact I think you would get away with corner posts hammered into the ground.

i have 2 at home,both glass,6x6 on bare soil,6x8 on gravely stuff,it also was on soil before it was moved,and both have been fine,the winds knock out fence pannels,and they still stand firm,it must be the weight of the glass,the bigger one is going on roll about again for next year,is easyer to move using poles and push,but not on my own lol

[pagan dreams]

ive got a 12x8 to move tomorrow its been sat on bare soil no anchorage of any kind altho the weight of the glass has kept it in place it had subsided slightly on one side causing a bump to appear in the gutter profile and cracking of the glass panes.glass can be very heavy especialy on large greenhouses so take care on the condition of your site as it may sink a bit.im gonna bury some concrete blocks in the soil and level them up then just screw frame onto them as i have no metal base,you may get away with a few randomly spaced blocks to help with support seeing u have a premade base.check that you are not in an exposed area unlike me who lives in a wind tunnel lol.good luck :-)

The greenhouse I have at the mo is a bit like Bren's photo I put some 3x2 slabs down on my plot and then built a breeze block wall sat sum tan timber on the wall and then bolted it all down the new one I got last month is like your's as in its got a base with it, I'm going to cut 4 posts (4x2 tan) drill and bolt to 4 corners and use some postcrete to anchor it down.

I've got a 6x6 that's just sitting on slabs under it's own weight, not fixed down. It hasn't moved in 2 years.
I'd still put some kind of base under the edges, just because the weight will cause it to sink into the earth.
an edging of breeze blocks on sand or something with the base of the greenhouse set right on the very edge should do it.

Exactly what I'm going to do with mine. Bury concrete blocks flush with the soil level and then screw the ali base to them. That should stop it lifting should any really gusty wind come but it'll be reasonably sheltered from anything from the north/east/southeast.
