Extensions

Is it possible to remove half of a party wall chimney stack?

Anonymous user 05/03/2024 - 2.30 PM

We're in the process of planning a loft extension and house refurbishments for our mid-terrace Victorian home. The existing plans are already in place. Our house shares a chimney stack with our neighbour. While our chimney breast is still intact, our previous neighbour removed their side of the breast many years ago, and it's currently supported by a gallows bracket. As part of the loft extension project, we're considering the removal of the chimney, and ideally, we'd like to get rid of the entire stack, as it would create additional space in the room. Keeping the stack would also necessitate inserting steel beams, as gallows brackets are no longer allowed. Since we have a good relationship with our neighbor, we plan to discuss the idea of removing the chimney stack and making the necessary fixes to his roof. Nevertheless, he might be hesitant to agree, as he tends to value preserving "original features." If our neighbour objects to removing his side of the stack, is it feasible to vertically divide the stack down the middle? To support his portion of the stack, is there a strapping method to attach his stack to the party wall that we need to extend upwards for the extension.

Even though we know what to do, as a builder we are not allowed to specify, you will need to go to a structural engineer who has the right indemnity insurance to specify the compliant way to deal with this.

The feasibility of removing half of a party wall chimney stack largely depends on various factors, including local building codes, structural considerations, and the agreement of the affected parties (the neighbours on both sides of the party wall). Here are some key points to consider: Local Building Codes Structural Integrity Party Wall Agreement Fireplace and Ventilation Considerations Cost: Altering a chimney stack can be a costly project, especially if it involves structural modifications and ensuring that the wall is properly supported after the alteration. In summary, it is possible to remove part of a party wall chimney stack, but it is a complex project that requires careful consideration, including legal, structural, and safety aspects. It is essential to consult with professionals and obtain the necessary permits while adhering to local regulations and ensuring the agreement of the affected parties.

Anything is doable. But get a structural engineer involved to do all the relevant calcs. Also when the stack is removed first floor joists will need trimming where they are short .
