How do conservation areas and Article 4 affect a drawing package in N6?

N6 (Highgate) conservation designations: there are 40 across Camden Council, Fitzrovia, Hampstead, Primrose Hill among them. Designation costs a N6 (Highgate) 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. Bloomsbury is the N6 (Highgate) designation that most often changes a drawing package design.

N6 (Highgate) and Article 4: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. A drawing package planned at a N6 address is checked against that direction first; Camden Council publishes the N6 (Highgate) extent, and the N6 line rarely follows the N6 (Highgate) boundary you would expect.

N6 (Highgate) below-ground policy: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Any drawing package in N6 (Highgate) that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Camden Council will want the N6 ground and groundwater position set out.

N6 (Highgate) housing stock: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross. Creative, affluent in Hampstead and Primrose Hill; dense mixed-use around Camden Town and Kings Cross; academic character in Bloomsbury. Read that before choosing a drawing package route in N6 (Highgate) — construction, not postcode, sets what is achievable. Camden Council charges £548 for a householder application and has 8 weeks to determine it.

N6 (Highgate) conservation designations: there are 29 across Haringey Council, Bruce Castle, Highgate Village, Muswell Hill among them. Designation costs a N6 (Highgate) 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. Crouch End is the N6 (Highgate) designation that most often changes a drawing package design.

N6 (Highgate) and Article 4: Borough-wide Article 4 for HMO conversions. A drawing package planned at a N6 address is checked against that direction first; Haringey Council publishes the N6 (Highgate) extent, and the N6 line rarely follows the N6 (Highgate) boundary you would expect.

N6 (Highgate) housing stock: Edwardian terraces in Crouch End, Muswell Hill; Victorian two-up-two-downs in Harringay Ladder; 1930s semi-detached in Muswell Hill; post-war in Tottenham. Muswell Hill and Crouch End have strong conservation coverage with clear loft/mansard precedents; Tottenham generally permissive. Read that before choosing a drawing package route in N6 (Highgate) — construction, not postcode, sets what is achievable. Haringey Council charges £548 for a householder application and has 8 weeks to determine it.
