Oxford City Council lists 18 conservation areas: Bartlemas, Beauchamp Lane, Binsey, Central University and City, Headington Hill, Headington Quarry, Iffley, Jericho, Littlemore, North Oxford Victorian Suburb, Old Headington, Old Marston, Osney Town, Oxford Stadium Sandy Lane, St Clement's and Iffley Road, Temple Cowley, Walton Manor, and Wolvercote with Godstow.
Jericho carries an Article 4 Direction served on 31 March 2011. The council's record for it removes permitted development rights for a change in roofing material and for rooflights on elevations facing a highway or waterway.
We would build a page that explains which jobs need permission, states the Jericho material change restriction and its date, and says that you check the address against the conservation area boundary and against any Article 4 direction before you quote.
