Does Hounslow planning policy restrict a building regulations package?

Hounslow conservation designations: there are 30 across Hounslow Council, Brentford, Chiswick, Bedford Park among them. Designation costs a Hounslow owner the permitted-development route: a building regulations package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Old Isleworth is the Hounslow designation that most often changes a building regulations package design.

Article 4 and your Hounslow building regulations package: Hounslow Council has made no borough-wide direction, so permitted development for a building regulations package in Hounslow generally survives outside Hounslow conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a W4 owner records that a building regulations package was lawful.

Which neighbouring authorities border Hounslow?

• Hillingdon — adjoining Hounslow, with 29 conservation areas centred on HA4. A building regulations package on the far side of the Hounslow line is determined by Hillingdon Council, so the Hounslow quote for building regulations drawings is checked against Hillingdon guidance before it is issued.
• Ealing — adjoining Hounslow, with 30 conservation areas centred on W3. A building regulations package on the far side of the Hounslow line is determined by Ealing Council, so the Hounslow quote for building regulations drawings is checked against Ealing guidance before it is issued.
• Hammersmith and Fulham — the Hammersmith and Fulham boundary runs against Hounslow, so a building regulations package a street from Hounslow is decided by Hammersmith & Fulham Council instead. Hammersmith and Fulham runs 45 conservation areas across W6 and its neighbours, which is why building regulations drawings priced for Hounslow are re-checked against Hammersmith and Fulham policy whenever the Hounslow address sits on that edge.
• Richmond upon Thames — cross the Hounslow boundary and Richmond Council takes the building regulations package instead, applying 72 conservation areas of its own around SW13. We re-price building regulations drawings at the Hounslow edge because Richmond upon Thames policy and Hounslow policy rarely align on building regulations package depth.
