How do conservation areas and Article 4 affect a drawing package in W3?

W3 (Acton) conservation designations: there are 30 across Ealing Council, Bedford Park, Acton Green, Hanwell among them. Designation costs a W3 (Acton) 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. Ealing Broadway is the W3 (Acton) designation that most often changes a drawing package design.

Article 4 and your W3 (Acton) drawing package: Article 4 for HMOs in specific streets in Acton, Ealing and Southall. At a W3 address that matters twice over, because Ealing Council applies the direction unevenly across W3 (Acton) — we read the W3 (Acton) policies map for the exact W3 address before quoting architectural drawings.

What W3 (Acton) is built from: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb. Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive. That mix decides the drawing package route in W3 (Acton) more than the postcode does, and it is what a Ealing Council case officer reads first. A householder application costs £548 paid to Ealing Council direct, with 8 weeks to a decision once validated.

W3 (Acton) conservation designations: there are 30 across Hounslow Council, Bedford Park, Old Isleworth, Brentford among them. Designation costs a W3 (Acton) 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. Brentford is the W3 (Acton) designation that most often changes a drawing package design.

Article 4 and your W3 (Acton) drawing package: Hounslow Council has made no borough-wide direction, so permitted development for a drawing package in W3 (Acton) generally survives outside W3 (Acton) conservation areas and listed curtilages.

What W3 (Acton) 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 drawing package route in W3 (Acton) 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.
