Can you still use gallows brackets?
In respect to this, do I need planning permission to take down a chimney?
Planning permission is only required for removal of chimneys if the property is a protected structure. You will need to review how floor joists at first-floor level are supported as these may be partly supported on the large chimney breast you propose to remove.
Moreover, how much does it cost to take down a chimney?
Average Cost of Chimney Removal The cost to remove a chimney averages between $2,000 and $4,000 for a full removal; however, chimney removal costs vary from one chimney to the next for a number of reasons.
If you discover that the chimney breast you want to remove is real, then you will almost certainly need to contact a structural engineer. Actual chimney breasts form part of the structure of a house – once removed, the addition of support beams may need to be incorporated to support any masonry above.
