Internal Soil Pipe

[RBZ5416]

I have a '70s semi & for reasons I can't begin to fathom, the soil pipe runs inside the house. It descends into the lounge & is simply boxed in. This provides an ideal sounding board to present anyone sitting in the lounge with a blow by blow account of everything that's occurring in the toilet! :oops:

I'm guessing that having the soil pipe moved outside would be a fairly major job, so was wondering if insulating the space in the box would help? I was thinking of maybe opening the boxing upstairs & filling the gap with polystyrene chips or similar. Obviously this would be a right pain if the boxing downstairs ever need opening.

I'd be grateful for any suggestions of how best to deal with this problem.

RBZ5416,
Polystyrene anything will be useless, you need something like rockwool acoustic matting and to fit this round the pipe before refitting the boxing.
