Removing chimney breast - Surely not simple?

[SimonD]

I've read a few threads of people removing chimney breasts as part of a refit or overhaul of a house.

The thing is, where a chimney stack goes up through a first floor, surely the joists are supported by the stack, like where they normally meet a wall? What's the 'norm' here. If you take out are stack, aren't you also removing the support for the joists?

I have a 'flu' chimney from my boiler in a cupboard in the kitchen I could get rid of, but if it's supporting the first floor I'd rather not!

Makes sense, thanks.

As per here, after searching for 'gallows brackets'.

So is this anticipating supporting the floor above by using the gallows brackets to support the remainingstack, and by proxy supporting the floor?

Thanks chaps. Good info.

Thanks chaps.

Some good info.

FWIW I have a chimney in my lounge - that's fine and staying. It's the one for the old boiler fly in the kitchen that should go as it's using up a lot of space in the corner of the kitchen and as the boiler flu is now out the back and through the wall it's just not needed anymore. If I got a professional to take down the chimney outside and then make good the roof I'm sure I could 'work downards' and finish removing it all internally...
