Hi!
I'll post some pictures this weekend while I finish up detailed what I have to work with.
Essentially, a 3.2m x 4.1m rear kitchen that I want to rebuild. I've gutted it ... all of the units / plaster (except the original plaster coving) / rotted flooring ... etc... except for the joists.
With open the chimney breast and install a concrete lintel at 2m high and 1m wide for a gas cooker.
It seems that the joists have been replaced previously with 50x100 (2 x 4) and a sleeper wall installed in the middle of the room (1.6m to each wall). It also seems that cavity walls are probably full and the original DPC might be shot (based on what we found upstairs.) The replacement joists sit go wall to wall and sit on top of that sleeper wall.
Based on newspaper found in the wall, I think it was done in 1989.
Anyway, I want to replace the joists with new 50 x 100, which is within building regs (1.6m span, 400 spacing).
What's the best way to replace them?
This is what I can come up with (and possible problems):
1. Use hold in wall and install a new DPC in the wall. Seems that they'll rot again.
2. Wall hangers. Good idea but seems that they'll come out of the same and will be a PITA to level.
3. Sleeper wall next to the main wall? Don't touch the wall with anything? Seems arduous.
4. Wooden wall plate with DPC in between? Could cause a problem in the long run.
I'll get more detail ... took about 3000 kg out last weekend ... old plaster, about 200 bricks under the floor and shoveled all the dirt out.
Will address airbricks and other problems shortly.
Many thanks for your help!
