Knock Through & Remove Chimney Breast

if your remove the whole chimney , you will have making good on the roof area.your structural engineer should tell you if the roof trusses are bearing upon the chimney , and may need further support. if you remove lower half only ,you will need steels placed upon pad stones. this again is one that has to be investigated by builder and structural engineer. you will also require to inform building control at your local council ,paying the (inspection fees) around £400.00 plus you will need building control sign off BEFORE any plaster board /boxing is placed over the steels.

As long as you get a structural engineer in for calculations and and a verified Builder they would support first floor joists and chimney so you can take out ground floor chimney and breasts.

Hello. With out more information I'm guessing it is not a shared stack . If you remove the full stack you will need to make the roof good with what ever tile or slate is on your roof . There is NEVER any roof trusses or spars, Perlings supported off the chimney stack . This is because of fire regs . Even in a old property there will be 2 inch clear on all timbers around the chimney. Basically you will have a u shape of timber around both stacks that is trimmed out to the existing wall. So in your roof you will need to make good the split spar where the chimney was and then felt batten and re tile. In your ceilings upstairs you will need to make good ceiling joists and plaster board the opening and replaster the ceilings . On the 1st floor level you will need to put new floor joists in between the existing trimmed that go into the existing wall. Make good floor and plaster board the ground floor ceilings. Be aware they may be a brick or concrete fire harth in the ist floor level that will need removing. Finally on the ground floor if you are on suspended floors you will need to remove the stack at least 150 mm below the level of the bottom of the floor joists for venterlation and again trim out the floor joists and make good floor . If it's a shared stack only go to bedroom ceiling height . Get an engineer to spec steels and pads . If you try to bury the steels above ceiling height you will then be into more roof work as the wall plate will need cutting out to allow the steel to sit on pads and masionary. If your on solid floors on ground level make sure any floor reinstatement is minimum off 100 mm concrete and well compacted hard core with some sand blinding insulation and dpc installed before concrete Hope this explains everything to help you .

To remove a chimney breast or the complete stack, that all depends on a number of issues, and every case is different (house design, layout,weight loading, distribution of loads, party wall position and cost versus effectiveness). Before you go any further, you need to find out if your property is within a conservation area or not,regarding the removal of the complete chimney stuck etc. If you are allowed, then you want to look at the position of the breast in relation to the house layout e.g. is it in the middle of the total house width or closer to one party wall or another or even closer to any external wall of the house (not a party wall), because that will effect the structural designs / cost of any support introduced to either support part of the breast or other. Usually Structural engineers prefer to introduce RSJs between Party Walls, because such walls will hardly move in any future refurbishment thus not jeopardizing the main structure and safety of the house. If such applies then you have to consider the cost of the Party Wall Surveyor agreements and fees. Therefore: its is always advisable to do your math = area in question effectiveness versus costs...and if the answer is Yes, then go for it, and notify your house insurance provider before starting operations.....BUT...please choose all professionals (Architect, Engineer, FMB, LABC etc building company) and reputable builder to do the job and NO...''Cowboy Builders'' as they are a lot of them running around in UK!! Good luck on all your endeavors. Kind regards Gus
