The building, and what it does to the job
Across this patch a large part of the housing has been built within the last decade and a half. The units stay and only the surface changes, so the whole job turns on what the carcasses will take. Services isolated before anything is lifted.
The drains run down the side alley to a gully and an inspection cover near the back door, and the sink waste has always gone out on that side of the house. The ragged band left when old tiles and laminate come off together is what usually decides upstand over full height. Sockets in a stud wall move more easily than sockets in brick.
Office conversions have shallow floor-to-ceiling zones and boxed services above the units, so measure the clearance for tilting a slab upright inside the room.
