Hi guys
I'm planning a self build side extension and assumed Id need a suspended timber floor as the site ground level drops 3-4 feet from one end to the other. As well as the fact the house currently has this type of floor as it's built on the slope.
However I'm thinking it may be possible to build up the cavity wall to floor level and infill with hardcore prior to laying a slab instead.
A few questions about doing this
Would this create too much pressure on the side of existing house with 3-4 feet of compressed fill against the current wall, bearing in mind this is currently above ground level?
Could this cause damp by breaching the existing dpc of existing external wall?
Would I need to put vents through the slab as there are vent bricks for the current floor that would be covered?
Any help or advice would be great!
