City of London conservation designations: there are 27 across City of London Corporation, Fleet Street, Whitefriars, St Paul's among them. Designation costs a City of London owner the permitted-development route: a party wall package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Smithfield is the City of London designation that most often changes a party wall package design.

Article 4 and your City of London party wall package: Multiple Article 4 Directions around office-to-residential, demolition, and shopfront changes.

• Westminster — adjoining City of London, with 56 conservation areas centred on SW1. A party wall package on the far side of the City of London line is determined by Westminster City Council, so the City of London quote for party wall services is checked against Westminster guidance before it is issued.
• Camden — adjoining City of London, with 40 conservation areas centred on NW1. A party wall package on the far side of the City of London line is determined by Camden Council, so the City of London quote for party wall services is checked against Camden guidance before it is issued.
• Islington — cross the City of London boundary and Islington Council takes the party wall package instead, applying 40 conservation areas of its own around N1.
