If you are intending to remove a chimney on a wall shared with your neighbour (the party wall) you will most likely have duties and obligations under The Party Wall Act. This is designed to resolve any disputes, which may arise, between neighbours when building work is carried out. The minimum requirements of the Act are that you notify your neighbour of the intended work. The Party Wall Act is not administered by Building Control, but a Government explanatory booklet can be obtained by contacting us on 01223 457118 or 457122 or contact the Government website at www.construction.dltr.gov.uk.bregs
