This may sound insane on first glance, but after looking into the costs, potential problems and home disruption associated with pouring a solid concrete slab for my conservatory (4m x 3m) - I have come up with a cunning plan!
I wondered if it would be possible to put great big posts into the ground (concreted in) and build up a frame from that. Double or triple tanalised joists, coach-bolted together, around the outside to support the conservatory itself, and then a normal joist setup for the inner floor bit. It would be like a very beefy raised-decking job in my mind.
Any ideas or suggestions?
Thanks. G

A 'Durabase' on legs.
Sounds promising.

You think it would work? I know that durabases are welded steel and so are stronger, but with beefy timbers, could I do it?
I realise no-ones gonna have had first hand experience of this, but I'd value any opinions guys...

It's possible, but you would have to get it designed by a structural engineer and then have it approved by your BCO and/or your mortgage company as it is not a straightforward structure.

My gues is that it would be even more expensive and more time-consuming than a simple concrete base.
