What local planning policy applies to a drawing package in HA7?

How designation changes a HA7 (Stanmore) drawing package: Harrow Council maintains 29 conservation areas, including Stanmore, Harrow Weald, Harrow on the Hill. Inside any of them a HA7 (Stanmore) drawing package 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. Stanmore sets the tone for HA7 (Stanmore) casework.

No blanket Article 4 over HA7 (Stanmore): Harrow Council has not withdrawn permitted development across HA7 (Stanmore), so a drawing package outside a HA7 (Stanmore) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a HA7 owner wants on file.

What HA7 (Stanmore) 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 drawing package route in HA7 (Stanmore) 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.

What happens if a HA7 property sits on a boundary?

• Hillingdon — cross the HA7 (Stanmore) boundary and Hillingdon Council takes the drawing package instead, applying 29 conservation areas of its own around HA4. We re-price architectural drawings at the HA7 (Stanmore) edge because Hillingdon policy and Harrow policy rarely align on drawing package depth.
• Barnet — the Barnet boundary runs against Harrow, so a drawing package a street from HA7 (Stanmore) is decided by Barnet Council instead. Barnet runs 20 conservation areas across N2 and its neighbours, which is why architectural drawings priced for HA7 (Stanmore) are re-checked against Barnet policy whenever the HA7 (Stanmore) address sits on that edge.
• Brent — the Brent boundary runs against Harrow, so a drawing package a street from HA7 (Stanmore) is decided by Brent Council instead. Brent runs 22 conservation areas across NW2 and its neighbours, which is why architectural drawings priced for HA7 (Stanmore) are re-checked against Brent policy whenever the HA7 (Stanmore) address sits on that edge.
