installing block and beam without cavity

[xisao]

Hi, im looking at installing a block and beam floor in a 1920 mid terrace house with a solid wall (no cavity)
will be fitted on ground floor was previously solid concrete (now removed) and this had been fitted incorrectly as it was bridging the original DPC. and causing damp
issue im facing is i can’t find any supporting material for this particular situation. All info is on newbuilds or homes built with cavity walls.
mostly all on newbuild properties where the concrete beams sit on the inside wall therfore everything fits in place

can anyone help me how to solve the issue im facing please?

Surely a new insulated and damp proofed slab would be cheaper and easier. Otherwise you'll have to remove bricks from the outer side of the wall to manoeuvre the beams in.

Build some sleeper walls, but in all likeyness foundations of that era won't be wide enough.
It sounds like a bugger of a job, I'd fit a suspended timber floor in that situation.

Hi thankyou for your quick replies. I would ideally want to go ahead with the block and beam main reason being high water table area beams cannot rot all
the problem with putting concrete slab in it will push damp into walls especially given the high water table, this has been well documented,
my other question is if i put the sleeper walls too close to the walls could that be a cause of concern for the damp as it would not allow air circulation between sleeper wall and building wall. ither option is to build a wall as in the diagaram i have upploaded what do you think?

or build the walls further away from walls as you would with a timber suspended floor all photos of B&B is with walls on the 4 sides
