What changes about a measured building survey in each part of Hillingdon?

How do conservation areas and Article 4 affect a measured building survey in Hillingdon?

Hillingdon conservation designations: there are 29 across Hillingdon Council, Ruislip Village, Northwood, Harefield among them. Designation costs a Hillingdon 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. Ickenham is the Hillingdon designation that most often changes a measured building survey design.

Hillingdon permitted development status: there is no borough-wide direction from Hillingdon Council, so a measured building survey 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.

Hillingdon housing stock: 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. Read that before choosing a measured building survey route in Hillingdon — construction, not postcode, sets what is achievable. Hillingdon Council charges £548 for a householder application and has 8 weeks to determine it.

Who decides a measured building survey on the edge of Hillingdon?

• Harrow — adjoining Hillingdon, with 29 conservation areas centred on HA1. A measured building survey on the far side of the Hillingdon line is determined by Harrow Council, so the Hillingdon quote for measured building surveys is checked against Harrow guidance before it is issued.
• Ealing — cross the Hillingdon boundary and Ealing Council takes the measured building survey instead, applying 30 conservation areas of its own around W3. We re-price measured building surveys at the Hillingdon edge because Ealing policy and Hillingdon policy rarely align on measured building survey depth.
• Hounslow — the Hounslow boundary runs against Hillingdon, so a measured building survey a street from Hillingdon is decided by Hounslow Council instead. Hounslow runs 30 conservation areas across W3 and its neighbours, which is why measured building surveys priced for Hillingdon are re-checked against Hounslow policy whenever the Hillingdon address sits on that edge.
