I'm interested in an external chimney breast being constructed. I have a detatched house and plenty of room for a breast to be built externally. Does anyone know if planning persmission is needed, a rough cost for construction, and most importantly, is this something general builders can undertake, or is it a specialist job? I've scoured the net for 'Chimney Builders' etc, but can find nothing that fits the bill. Theres a wealth of info for breast removal, but nothing for building!
Any help would be most appreciated.
