Firstly, apologies if I'm requestioning what's already been answered in the sticky but it didn't seem to quite fit the bill for my situation.
In short, I have recently knocked down the dividing wall between my kitchen and dining room and am left with part tiles on a concrete base and part flooboard. Between them is what remains of the wall at foundation level & due to where I've removed the course of bricks this is about an inch or so below the floorboard level (which is the highest point). There is also a gap of maybe 1cm maximum between where the floorboards would have butted up against the wall (I assume the expansion gap?). On the tile/concrete slap side this butts rights up to the wall but is a cm or so below it. Between the floorboards and tiled/concrete part there is probably 2cm in height difference.
My plan is to lay some kind of laminate/engineered wood or tiles as I've been advised the former may not be suitable for a wet kitchen environment. I intend on laying some kind of thin plywood throughout to form a continuous base but am unsure about getting my levels to match. I was thinking slapping some render over the top of the old foundation wall to bring it roughly level with the tiled/concrete floor, then a screed to bring it up to the level of the floorboards with the ply then going over everything. Would this work? My issue is what to do about the gap from the top of the foundation wall as if I lay a screed it may find its way through the gap between the floorboards and straight into the void but I don't want to put the render right up to the edges of the floorboards as this will mean I lose the expansion gap.
If I haven't lost you already any advice would be appreciated! Also, do I need to consider different adhesives etc for the concrete and floorboard floor sections?
