Chimney stack/breast removal

[19Mark78]

Hi all

Hope you can help, I've got the builders in to remove the chimney stack and breast that run through 2 bedrooms and 2 downstairs rooms, they've completed the removal and are now in the process of studding the walls where the breasts were in preperation for plaster board, however they have NOT rebuilt the internal wall so there is a single brick wall to the outside all the way up through the rooms, i know they are being studded but my concern is for noise and cold, it's not a load bearing wall as such in that all the joists run the opposite way on both floors.
Would any of you find it a concern for any other reasons?
Appreciate any advice... Thanks

Surely the internal wall is the chimney breast that has been removed, leaving a single skin as the retained back of the old chimney flue/stack.

I believe such structural changes need building regs approval, and that would/will have taken into account any impact on the remaining structure.

Do you have any "before" pics?

Thanks for the reply.
Some extra photos

I don't think the stud work materially adds to the structural integrity of the walls, but don't know if the additional brickwork is needed. Those are two pretty hefty chimneys by the look of things.

Maybe a quick word with a structural engineer before its closed up.

How strange. Surely a lot of the volume you gained has been eaten up by that studwork over the entire walls, especially on what looks a long narrow room anyway. Normal way would be to stud or build out the gap flush with walls either side and replaster - unless there's a plan for some insulation?

Yes cdbe, it's having kingspan insulation, also having the tv built into the studwork to finish flush.

The chimneys might also have provided restraint to the walls either side of them especially as the joists run the other way and a dividing wall has been removed, but, as said, really needs an SE to assess on site.

Have you applied for building regulation approval?

As others say or imply you need bldg. regs approval for structural alterations and surely it is best to obtain this before carrying out demolition work on site , particularly of a fairly substantial brick chimney breast. I don't know if it was essential on your wall but the chimney breast would provide some buttressing to the wall . I would get in touch with building control straight away if I was you.
