Is it feasible to sit the column in line with the inner block work of the cavity wall to avoid it creating a large pillar in what will be the kitchen cabinet wall? how will the dpc/cavity tray work if so as there will be a gap in that inner skin where the steel sits. Thanks for the responses so far.

Hi All, I’m new here and was hoping you could help. We are adding a wraparound extension to our 1930’s semi and the structural engineer has spec’d “goalpost” steels across the back of the original rear wall, supported at 3 points by UC steels on concrete pads. Two of the pads will be under the existing suspended timber floor and will require “pits” to be dug however one of them will be effectively on top of / in line with the new foundations. The pad required is 700Lx700Wx300Deep and the foundation is 600wide x 450deep. My question is how do I create the required pad? Do I simply widen the foundation at that point to the 700x700 dimension and utilise the additional depth of the foundation? The steel will be below ground level if I do the above once backfilled and concrete goes down for floors so my next question is……How do I protect the steelwork that’s below ground level from rust, degradation over time? Hope the above is clear but happy to elaborate further if needed. Thanks Simon

Hi all I’m about to start my wraparound extension on my 1930’s semi and I am absolutely certain I’m going to have more questions than is probably reasonable about many aspects of the build. I’m hoping that here I will be able to find the guidance I need and also, I’ll be able to guide others should I have anything I can contribute to their efforts. Here’s to mess and upheaval! Simon
