Which EC4Y postcodes does this drawing package service cover?
Every EC4Y postcode district we draw in, the stock that dominates
it and the authority that validates a drawing package there. EC4Y fees below are the
statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|
| EC4Y | Temple | mixed Victorian and inter-war stock | Temple sits wholly inside EC4Y, so City of London Corporation validates every drawing package submitted from an EC4Y address. |

| EC2Y | Barbican | Listed Brutalist apartments (Barbican Estate) | Adjoining district to EC4Y, also inside City of London for drawing package purposes. |

What changes about a drawing package in each part of EC4Y?
Roof pitch, wall build-up and plot depth change every few EC4Y
streets, and each one changes what a drawing package can achieve at that address.

Does EC4Y planning policy restrict a drawing package?
EC4Y (Temple) conservation designations: there are 27 across City of London Corporation, St Paul's, Barbican, Smithfield among them. Designation costs a EC4Y (Temple) owner the permitted-development route: a drawing 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 EC4Y (Temple) designation that most often changes a drawing package design.
Article 4 and your EC4Y (Temple) drawing package: Multiple Article 4 Directions around office-to-residential, demolition, and shopfront changes. At a EC4Y address that matters twice over, because City of London Corporation applies the direction unevenly across EC4Y (Temple) — we read the EC4Y (Temple) policies map for the exact EC4Y address before quoting architectural drawings.
What EC4Y (Temple) 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. That mix decides the drawing package route in EC4Y (Temple) more than the postcode does, and it is what a City of London Corporation case officer reads first. A householder application costs £548 paid to City of London Corporation direct, with 8 weeks to a decision once validated.
Who decides a drawing package on the edge of EC4Y?
- Tower Hamlets — cross the EC4Y (Temple) boundary and Tower Hamlets Council takes the drawing package instead, applying 58 conservation areas of its own around E1. We re-price architectural drawings at the EC4Y (Temple) edge because Tower Hamlets policy and City of London policy rarely align on drawing package depth.
- Southwark — cross the EC4Y (Temple) boundary and Southwark Council takes the drawing package instead, applying 43 conservation areas of its own around SE1. We re-price architectural drawings at the EC4Y (Temple) edge because Southwark policy and City of London policy rarely align on drawing package depth.
- Westminster — adjoining EC4Y (Temple), with 56 conservation areas centred on SW1. A drawing package on the far side of the EC4Y (Temple) line is determined by Westminster City Council, so the EC4Y (Temple) quote for architectural drawings is checked against Westminster guidance before it is issued.
- Camden — adjoining EC4Y (Temple), with 40 conservation areas centred on NW1. A drawing package on the far side of the EC4Y (Temple) line is determined by Camden Council, so the EC4Y (Temple) quote for architectural drawings is checked against Camden guidance before it is issued.
