Removal of Chimney.

Pentax

Hi All,

I have a 1970's house in Dublin and I was wondering about removing the chimney from the floor up to the roof. The chimney is in the center of the house and is not shared with a neighbour. Has anyone completed something similar and was it worth all the disruption?

Thank you

Why do you want to remove it and what is it built with

You'll need to verify that the chimney isn't structural. Then once that's done then I think that it would give you a reasonable return in terms of efficiency as well as well as returning some floor-space. It's not an uncommon modification.

Its a pretty common thing to do where I live to regain space in small houses. One of my neighbours just took theirs out a couple of months ago. We have to leave a dummy chimney stack on top though for aesthetic reasons given the age of the houses. (All built around 1900)

Just make sure to start at the top and work down

I did this to my mid terrace house a few years ago, massive disruption but defo worth it given my house is 88 m2 and the downstairs config was very sub optimal.

I took advantage of disruption to get a few things done too. PM me if you want more details

Hi,

I would like to remove it so I can gain extra space upstairs and downstairs. I would also like to open up the ground floor which is not possible currently with the chimney stack located in the middle of the house.

The Chimney is concrete built.

Hi,

As the chimney is located in the middle of the house several of the floor joists run into the the chimney for support, so I would imagine so additional support would be required at the first floor level. Wont be an issue in the attic or the ground floor as I intend to remove the wooden suspended floor.

Good point 🤣.

However someone did suggest removing the chimney from the ground floor and support the first floor with RSJ's. Not sure if there would be and benefit in this given the price of the steel and its installation.

If the chimney is mass concrete you may be able to remove it within the rooms, leave it in situ from ceiling up.

Dowl and reinforce around the joists, but this will depend on a mass concrete wall to carry it.

It's not unusual to build a fully suspended block wall in construction without a H beam under it.
