Does Barnet planning policy restrict a building regulations package?

Conservation areas covering Barnet: Barnet Council runs 20, and Golders Green, Monken Hadley, Hampstead Garden Suburb are the ones Barnet owners meet most. A building regulations package inside a Barnet conservation area loses permitted development, so the Barnet submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Hampstead Garden Suburb a building regulations package is judged on the street elevation first.

No blanket Article 4 over Barnet: Barnet Council has not withdrawn permitted development across Barnet, so a building regulations package outside a Barnet conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a N2 owner wants on file.

The building fabric around Barnet: 1930s semi-detached dominates; Edwardian villas in Muswell Hill, Finchley; Garden Suburb Arts & Crafts in Hampstead Garden Suburb; post-war flats in Colindale. Suburban outer-London borough; permitted development used heavily; Hampstead Garden Suburb has its own residents' trust with additional design controls. A building regulations package in Barnet is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Barnet Council.

What happens if a Barnet property sits on a boundary?

• Enfield — adjoining Barnet, with 22 conservation areas centred on EN1. A building regulations package on the far side of the Barnet line is determined by Enfield Council, so the Barnet quote for building regulations drawings is checked against Enfield guidance before it is issued.
• Harrow — cross the Barnet boundary and Harrow Council takes the building regulations package instead, applying 29 conservation areas of its own around HA1. We re-price building regulations drawings at the Barnet edge because Harrow policy and Barnet policy rarely align on building regulations package depth.
• Brent — cross the Barnet boundary and Brent Council takes the building regulations package instead, applying 22 conservation areas of its own around NW2. We re-price building regulations drawings at the Barnet edge because Brent policy and Barnet policy rarely align on building regulations package depth.
