Does NW7 planning policy restrict a drawing package?

NW7 (Mill Hill) conservation designations: there are 20 across Barnet Council, Monken Hadley, Hampstead Garden Suburb, Mill Hill among them. Designation costs a NW7 (Mill Hill) 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. Mill Hill is the NW7 (Mill Hill) designation that most often changes a drawing package design.

No blanket Article 4 over NW7 (Mill Hill): Barnet Council has not withdrawn permitted development across NW7 (Mill Hill), so a drawing package outside a NW7 (Mill Hill) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a NW7 owner wants on file.

What NW7 (Mill Hill) is built from: 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. That mix decides the drawing package route in NW7 (Mill Hill) more than the postcode does, and it is what a Barnet Council case officer reads first. A householder application costs £548 paid to Barnet Council direct, with 8 weeks to a decision once validated.
