Just been back to finish...

[Stretch]

I didnt think the upstands could go behind hobs, especially gas ones???

We checked the MI's. The tolerance was sufficient

That rsj must have been a git to work around, the walls just fit in nicely.
nice and tidy, did you do the painting?

We didn't do any painting apart from mist coating the new plaster and a mist coat and two top coats on the ceiling which was pulled down, reboarded and skimmed.

With the RSJ, we D&Ded plasterboard to the underside at 295mm wide then beaded and flattened off.

We then used this RSJ as a datum to build either side of. The wall unit directly underneath is a 720mm medium wall cut down to 660mm plus 20mm of cornice on top. The fascia, which is ABS edged was cut and re-edged to suit.



It was a git though....as with all extensions, they are never built true and parallel to existing walls so there was a bit of "manipulation" to get all the wall units screwed together and a lot of finite adjustment on the fascias afterwards to get them level. All worked out well in the end though. I always like a challenge!!

Incidentally... another planning/design error. In the first pic of the finished job, the wall unit that hangs to the right of the tower run was supposed to be a 1000 wide. However, due to an error by me the biggest gap we could create was 980mm (and that was without a décor end) so we reduced the wall unit to 950mm and cut and re-edged the RH fascia from 500 to 450. It's all about getting over problems on site as they occur.
