Does Barnet planning policy restrict a party wall package?

Conservation areas covering Barnet: Barnet Council runs 20, and Mill Hill, Hendon, Golders Green are the ones Barnet owners meet most. A party wall 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 Hendon a party wall package is judged on the street elevation first.

Article 4 and your Barnet party wall package: Barnet Council has made no borough-wide direction, so permitted development for a party wall package in Barnet generally survives outside Barnet conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a N2 owner records that a party wall package was lawful.

Barnet housing stock: 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. Read that before choosing a party wall package route in Barnet — construction, not postcode, sets what is achievable. Barnet Council charges £548 for a householder application and has 8 weeks to determine it.

What happens if a Barnet property sits on a boundary?

• Brent — adjoining Barnet, with 22 conservation areas centred on NW2. A party wall package on the far side of the Barnet line is determined by Brent Council, so the Barnet quote for party wall services is checked against Brent guidance before it is issued.
• Camden — adjoining Barnet, with 40 conservation areas centred on NW1. A party wall package on the far side of the Barnet line is determined by Camden Council, so the Barnet quote for party wall services is checked against Camden guidance before it is issued.
• Haringey — adjoining Barnet, with 29 conservation areas centred on N4. A party wall package on the far side of the Barnet line is determined by Haringey Council, so the Barnet quote for party wall services is checked against Haringey guidance before it is issued.
• Enfield — cross the Barnet boundary and Enfield Council takes the party wall package instead, applying 22 conservation areas of its own around EN1. We re-price party wall services at the Barnet edge because Enfield policy and Barnet policy rarely align on party wall package depth.
