Conservation & Article 4
Birmingham has 30+ conservation areas including the Jewellery Quarter, Edgbaston, Moseley and Bournville. Article 4 directions in Bournville cover external materials, windows and rooflights — even PD-sized extensions need consent.
Local quirks that move the price
Cellars and Victorian sub-floors in Moseley/Kings Heath frequently require tanking specs adding £4-9k. Tree Preservation Orders are dense across south Birmingham (B13-B17) — always check before quoting rear excavation. Bay-fronted terraces in Selly Park typically need a Party Wall Award on both sides.
