City of London conservation designations: there are 27 across City of London Corporation, St Paul's, Barbican, Smithfield among them. Designation costs a City of London owner the permitted-development route: a measured building survey then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks.

City of London and Article 4: Multiple Article 4 Directions around office-to-residential, demolition, and shopfront changes. A measured building survey planned at a EC1A address is checked against that direction first; City of London Corporation publishes the City of London extent, and the EC1A line rarely follows the City of London boundary you would expect.

What City of London is built from: Very limited residential — Barbican Estate (listed post-war), Golden Lane Estate, modern luxury flats; overwhelmingly commercial. Overwhelmingly commercial; residential planning extremely constrained; one of the two highest listed-building densities in London.

A householder application costs £548 paid to City of London Corporation direct, with 8 weeks to a decision once validated.
