Answers for Haringey

Does Haringey have an Article 4 Direction?

Yes — Borough-wide Article 4 for HMO conversions.

What does Article 4 remove?

Article 4 removes specific Permitted Development rights — typically the right to convert a single dwelling (C3) to an HMO (C4), or office (B1) to residential (C3), without full planning permission. The right is removed only where the Direction applies.

Can I still extend my home in Haringey under Article 4?

Yes. Article 4 in most London boroughs targets HMO conversions and office-to-residential, not householder extensions. Standard rear extensions and loft conversions remain available under Permitted Development unless your property is in a conservation area or is listed.

How do I check if my address is covered by Article 4 in Haringey?

Check the planning portal at Haringey Council or call us — we look up the Article 4 status for your specific address before quoting.

What happens if I build under PD when Article 4 applies?

If Article 4 applies and you build without planning, you face enforcement action: a retrospective application, a stop notice, or in serious cases an enforcement notice requiring reversal. Always check before starting.

N10Muswell HillEdwardian villas, 1930s semi-detachedMuswell Hill is split at N10. Either Haringey Council or Barnet Council can determine a scheme inside an Article 4 area here, so the N10 address is checked against both policies maps first.

Roof pitch, wall build-up and plot depth change every few Haringey streets, and each one changes what a scheme inside an Article 4 area can achieve at that address.

What local planning policy applies to a scheme inside an Article 4 area in Haringey?

How designation changes a Haringey scheme inside an Article 4 area: Haringey Council maintains 29 conservation areas, including Muswell Hill, Crouch End, Tottenham Green. Inside any of them a Haringey scheme inside an Article 4 area 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. Highgate Village sets the tone for Haringey casework.

Haringey and Article 4: Borough-wide Article 4 for HMO conversions. A scheme inside an Article 4 area planned at a N4 address is checked against that direction first; Haringey Council publishes the Haringey extent, and the N4 line rarely follows the Haringey boundary you would expect.

What Haringey is built from: 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. That mix decides the scheme inside an Article 4 area route in Haringey more than the postcode does.
