Paving slabs on a good sharp/soft/OPC base?

Mine is is of a similar size, and was two courses of single bricks on
concrete (not sure of the width & depth as I didn't do it) Maybe 15cm x
20cm?). The greenhouse was screwed down onto the bricks. That may seem
like overkill, but with the sort of winds we seem to be getting these
days it might be a reasonable precaution.

holding it down in strong winds should be your first concern .....

concrete blocks laid on sides or paving slabs

No need for 'real' foundations

+1, they're so light, and able to tolerate a little ground movement.

Polytunnels are a better bet.

You disagree, auto-contradicting senile Rodent? Well, that's a new one! LOL

Not sure about that. Perhaps if the panes are fairly small, but if
they're single Dutch Lights, even a slight amount of ground movement
will cause the rectangular side frames to distort to parallelograms,
putting stress on the glass, which then cracks. DAMHIKT.

Indeed. I specified toughened glass panes for my greenhouse and I'm very
glad I did. Twice, strange wind eddies sucked out the end roof panel
(about 1500 x 300mm) and deposited - fortunately on the lawn - five
metres away. Being toughened glass, the panel didn't break.
