Hi,


I am seeking guidance regarding some work I previously carried out on my property without Building Control approval, which I am now looking to regularise. Please see the attached photographs for reference.





When I purchased the house, it was formerly a council property and the roof covering had been replaced approximately 2–3 years prior. During that work, the chimney stack had been reduced to loft level and left in place, as it was providing support to a timber purlin on one side of the roof. The purlin had been cut on either side of the chimney stack.





Subsequently, I installed an additional timber purlin of the same size and length alongside the existing one, securely coach-bolting the two together. Once this was in place, I removed the remaining chimney stack entirely. The chimney was not providing support to any other structural elements aside from the purlin/roof arrangement described above.





I would be grateful if you could advise whether this work would be considered acceptable by Building Control, and what would be required for it to be approved retrospectively.





Thank you for your time and assistance.

We need photos really. Is the purlin supported by uprights that have been 'bird-mouthed'?
