Space gain from Chimney Breast removal

[BigDataPro]

Searched all over the internet to figure out how much internal space will be gained upon removal of Chimney Breast on a Semi-detached 1930's property, but failed to get an idea.

Has any one done it or seen it removed and how much inside space does it provide? I am trying to decide if it is worth doing by comparing Cost vs Space gained.

Without wishing to sound stupid......surely the size of the breast?

Edit: To be clear, I'm not being facetious. Unless it's some super weird design, you should be able to remove the breast completely back to the wall it's attached to giving a flush wall

Don't they teach that thing at primary school where you measure the area of a big square then measure the area of a smaller square add the two together to get the combined area?

In older houses the chimney breast is integral to the supporting wall and travels up the house through to the roof so will require complete removal on all floors and the roof so is very rarely worth it if at all possible. I can't remember seeing any design programme that's done this and haven't seen a renovation that has done this either.

No you are right. But I am unable to figure out the Chimney projection in Feet/CM/Inches that is inside the living room. So I was hoping that most of the standard chimenys will have standard space gains when removed.

I'm not with you? Surely you can measure the big box projecting out of the wall? That'll no longer be there after....

Depth * Width * Height ....

Questions:
1. Are you planning to remove the stack as well, or just the part in the room?
2. If you're just removing the breast and not the stack, you may need to support the stack (or leave part of the breast in place to do that) - speak to a structural engineer. 3. Is it a bungalow, or multi-storey building? (If multi-storey, are you planning to remove from all floors?)
4. Is it on the side that is attached to the neighbour, and do they have a chimney in the same place? - speak to a structural engineer.

5. Is this even real?

Post some pictures over on https://forum.buildhub.org.uk/ and you'll get your answers.

Could be prohibitively expensive (even more-so if property is two storey) as it'll probably be structural/load bearing.

As for space gain, i too can't understand why it wouldn't be anything other than the bit sticking out of the wall...

If he gets the removal wrong, he could be caught in a landslide
