I live in a first floor flat in a victoriian house conversion. I'm doing my kitchen very soon but the floor slopes toward the side of the house (it's an end terrace) the sloping difference is about 10cm/4inches from one end to the other. The size of the kitchen is 3m x 2m.
I'd rather not use screading and ripping up the floorboards and batoning the joists is too expensive.
what other options do i have or ideas.
