My daughter has a chimney breast in her kitchen and I assume a covered fireplace. This is as a result of two rooms being knocked into one sometime in the past by a previous owner. The bedroom above also has a covered fireplace with an air brick. And the chimney is capped by a slab. This is all on an outside non shared wall. I wanted to re open the fireplace and make the opening higher in order to house a cooker and extractor.
What do I need to do, and do I need planning permission?
Thanks
