How do conservation areas and Article 4 affect a drawing package in Hillingdon?
How designation changes a Hillingdon drawing package: Hillingdon Council maintains 29 conservation areas, including Northwood, Harefield, Ickenham. Inside any of them a Hillingdon drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Northwood sets the tone for Hillingdon casework.
Hillingdon permitted development status: there is no borough-wide direction from Hillingdon Council, so a drawing package at a HA4 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Hillingdon sale to argue it later.
The building fabric around Hillingdon: 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow. Largest outer west London borough; significant Green Belt; Heathrow noise contours affect planning decisions in Harmondsworth and Sipson. A drawing package in Hillingdon is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Hillingdon Council.
What happens if a Hillingdon property sits on a boundary?
- Harrow — cross the Hillingdon boundary and Harrow Council takes the drawing package instead, applying 29 conservation areas of its own around HA1. We re-price architectural drawings at the Hillingdon edge because Harrow policy and Hillingdon policy rarely align on drawing package depth.
- Ealing — the Ealing boundary runs against Hillingdon, so a drawing package a street from Hillingdon is decided by Ealing Council instead. Ealing runs 30 conservation areas across W3 and its neighbours, which is why architectural drawings priced for Hillingdon are re-checked against Ealing policy whenever the Hillingdon address sits on that edge.
- Hounslow — the Hounslow boundary runs against Hillingdon, so a drawing package a street from Hillingdon is decided by Hounslow Council instead. Hounslow runs 30 conservation areas across W3 and its neighbours, which is why architectural drawings priced for Hillingdon are re-checked against Hounslow policy whenever the Hillingdon address sits on that edge.
