I've just been down the timber yard, sawn 25x75 is a bit scaggy. 2nd

taken in to account.

Don't know if your preference for assembly is screwing or nailing, but I
found that two 4" twinthread quickscreews (Screwfix) per joint made for
very strong framing even when screwed into the end grain of the wood.

I thought Jabfloor was polystrene, i.e. not to be in contact with PVC
wiring?

It is - hence why I put all the wires in oval conduit.
