Does Hounslow planning policy restrict a planning drawing set?

How designation changes a Hounslow planning drawing set: Hounslow Council maintains 30 conservation areas, including Old Isleworth, Brentford, Chiswick. Inside any of them a Hounslow planning drawing set 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. Chiswick sets the tone for Hounslow casework.

Hounslow permitted development status: there is no borough-wide direction from Hounslow Council, so a planning drawing set at a W4 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Hounslow sale to argue it later.

What Hounslow is built from: Edwardian villas in Chiswick and Turnham Green; Georgian in Isleworth; 1930s semi-detached in Hounslow and Feltham; riverside new-build in Brentford. Chiswick is one of west London's most conservation-controlled areas; outer Hounslow is permissive suburban. That mix decides the planning drawing set route in Hounslow more than the postcode does, and it is what a Hounslow Council case officer reads first. A householder application costs £548 paid to Hounslow Council direct, with 8 weeks to a decision once validated.

Which neighbouring authorities border Hounslow?

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