Securing New Greenhouse?

[TattyJJ]

I know it would be the best way of doing it....
But it's a lot of work, and yet more cost. Finances are strained after just moving house!
Plus not planning to stay here more than 2/3 years, if was going to be here for ages then sure I'd prob do it. But the prospect of having to undo it after just 2 or 3 seasons doesn't thrill me.

It would work well and super easy, but also would mean all sides would have to line up with the slab edges. Pretty unlikely....

Not really, I'm using 600mmx 600mm slabs and my greenhouse is 1200x1800 which are 600 modules i.e. 2 slabs x 3 slabs
