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

How designation changes a Harrow measured building survey: Harrow Council maintains 29 conservation areas, including Pinner Village, Stanmore, Harrow Weald. Inside any of them a Harrow measured building survey 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. Harrow on the Hill sets the tone for Harrow casework.

No blanket Article 4 over Harrow: Harrow Council has not withdrawn permitted development across Harrow, so a measured building survey outside a Harrow conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a HA1 owner wants on file.

What Harrow is built from: 1930s semi-detached dominates; Edwardian villas in Harrow on the Hill and Pinner; Metropolitan Green Belt in Stanmore and Harrow Weald; post-war flats around Harrow Central. Outer north-west London suburban; Harrow on the Hill has exceptionally strict heritage controls; rest of borough permissive. That mix decides the measured building survey route in Harrow more than the postcode does, and it is what a Harrow Council case officer reads first. A householder application costs £548 paid to Harrow Council direct, with 8 weeks to a decision once validated.

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