we got planning permission to remove our large conservatory and replace it with a solid extension, the old conservatory was a screed floor with no insulation, so we had to rip it out. we are now thinking of putting a block/beam floor in instead of a slab floor.. the only thing on my mind is we are having a 215mm solid block wall being built instead of a brick/block cavity wall. how would i got about bearing the end of the beams, would i just notch out openings in the blocks, or better to built a sleeper wall right up next to the solid wall to rest the beams on.
another thing i wanted to know is, you need 150mm gap below the bottom of the beam for air circulation, the beam itself is 150mm, and then i will need say 75mm insulation + 50mm screed and 22mm timber flooring + 3mm underlay. am i right in thinking i will need to excavate -450mm from the current ffl of the house.
also i read somewhere that the 150mm gap below the block and beams has to have a kind of concrete base???
thanks in advance for any replies
