4 tier portable green house

[echokilo]

I got my mum a 4 tier portable greenhouse - one of the ones with the plastic zip up cover over the green plastic coated metal frame. It's set up in quite a sheltered spot but yesterday in the storm it blew over and all the seedlings etc were destroyed and she is really upset as now she needs to start again ...... how can we fasten it back to the wall? The problem is how do we secure the frame of it to the wall without cutting holes in the plastic "tent" ype cover which drops over the frame and zips up at the front ... it looks like this although this is an advert for the cover only:

I had this problem but couldn't fix it anywhere as it stands against my shed and if it's fixed you can't remove the cover if it needs replacing which they do from time to time as they are not all that robust.
I put a layer of house bricks on the very bottom shelf . You can still put some seed trays on top of the bricks .
It hasn't moved since.

I hold mine down by placing bricks on the bottom shelf.
