Highgate to Crouch End: 29 protected areas across Haringey
Twenty-nine conservation areas cover parts of Haringey, Highgate Village to Bruce Castle. What designation takes away, what a heritage statement is obliged to say, and which alterations come through it intact.
The national register records 33 covering about 887 hectares, of which 28 carry a designation date — the earliest from 21 December 1967. Inside them Article 2(3) removes Class A side extensions, cladding and Class B roof enlargement, which is why Haringey dormers are approved at 70% rather than the borough’s 89.5%.

Sources: conservation and Article 4 registers from the MHCLG Planning Data Platform, retrieved 1 September 2026, excluding revoked entries and with hectares computed from the published boundaries; the Datahub row from the Planning London Datahub, retrieved 15 August 2026, phrase-matched and comparable within Haringey only; decision figures from MHCLG PS1 and PS2, twelve quarters to March 2026. Five Haringey designations carry no date in the register, which is a gap in the data rather than in the designation.
Where are Haringey’s conservation areas, and where does Article 4 sit on top of them?
Haringey is one of the boroughs where both layers repay a look, because the council has published both. The map draws the conservation area boundaries and the Article 4 direction areas from the national register, and a postcode typed into it is matched in the browser rather than on a server. What it cannot do is arbitrate an edge: the polygons are simplified, and where a boundary appears to clip the back of a plot, that question goes to the council rather than to the screen.
Haringey has been designating for a long time, and the record shows it. The earliest boundary here was made on 21 December 1967, within weeks of the Civic Amenities Act creating the designation at all; the most recent dates from 10 November 2008. Highgate is the giant at 225.8 hectares, out of roughly 887 hectares designated across the borough, while Lordship Lane covers under a hectare — the same phrase, conservation area, doing very different work at the two ends of that scale. The second layer matters more here than in most of London. Twenty-five Article 4 direction areas are on the register for Haringey, and where one covers your street, work you would expect to be permitted development — a replacement front window, a porch, sometimes a rear extension — needs a full application instead. Five areas carry no designation date at all, and twenty-five have a council document attached to them.

Answers for Haringey
How many conservation areas does Haringey have?
Highgate Village and Muswell Hill in the west, Tottenham Green and Bruce Castle in the east: the 29 designated areas are spread right across the borough. They sit over unusually old housing. VOA stock figures at 31 March 2025 put 36.5% of Haringey's 114,960 dwellings in buildings raised before 1900, and another 17.5% in the 1900 to 1918 period.
What changes need planning in a Haringey conservation area?
Any external alteration visible from a public space typically requires full planning permission inside a conservation area: roof additions, dormers, replacement windows, rendering, hardstanding, and demolition. Internal works generally do not, unless the property is also listed.
Do I need a Heritage Statement in Haringey?
Yes, and a generic one does more harm than none. The statement has to engage with the character appraisal written for that particular Haringey area, name the assets your proposal touches — unlisted buildings that contribute to the area included — and set out plainly how what you are proposing preserves or enhances whatever the designation was made to hold. Ours is drafted alongside the drawings, not bolted on when validation stalls.
Can I have a roof extension or mansard in a Haringey conservation area?
Put the addition at the back and the answer is usually yes. Mansards and dormers on rear slopes are consented across designated parts of north and inner London whenever the profile picks up the terrace it belongs to. Dormers on a principal elevation are refused very nearly without exception, because they alter the roofline designation exists to hold steady. That single distinction decides most of what happens in a Highgate or Crouch End case.
How long does conservation area approval take in Haringey?
Eight weeks is the statutory determination period Haringey works to on a householder application. Conservation officer consultation is the usual reason a designated case overruns it. Budget eleven to fourteen weeks from validation through to decision, and build the programme around that figure rather than the statutory one.

Dominant stock
What it means for a conservation area application
N4
Finsbury Park / Stroud Green
Victorian terraces, post-war estates
Three councils share N4 at Finsbury Park and Stroud Green — Haringey, Islington, Hackney. Three sets of conservation guidance with them. Which one determines your case follows the street rather than the outward code, so that is settled first.
N8
Crouch End / Hornsey
Edwardian terraces, Victorian villas
N8 covers Crouch End / Hornsey only; Haringey Council handles the conservation area application.
N10
Muswell Hill
Edwardian villas, 1930s semi-detached
N10 is largely Muswell Hill and largely Haringey, but its western edge crosses into Barnet. Both policies maps get checked against the address, because Muswell Hill's conservation guidance stops dead at the boundary.
N15
Seven Sisters / South Tottenham
Victorian terraces, post-war estates
N15 covers Seven Sisters / South Tottenham only; Haringey Council handles the conservation area application.
N17
Tottenham
Victorian terraces, post-war estates
N17 covers Tottenham only; Haringey Council handles the conservation area application.
N22
Wood Green / Alexandra Palace
Edwardian terraces, post-war flats
A conservation area application at an N22 address in Wood Green / Alexandra Palace is determined by Haringey Council under its own Local Plan policies for Wood Green / Alexandra Palace.
N6
Highgate
Georgian villas, Victorian and Edwardian semis
N6 straddles a boundary: Highgate addresses fall to Camden Council or Haringey Council, so confirm which authority validates the conservation area application before submitting N6 drawings.
Which Haringey neighbourhoods suit a conservation area application best?
Roof pitch, wall build-up and plot depth move within a few Haringey streets. A Crouch End terrace and a Tottenham semi a mile apart will take entirely different rear additions before the design starts arguing with the designation.
Tottenham (N15, N17) — Victorian terraces, post-war estates defines Tottenham, where victorian terraces, post-war estates set what a conservation area application can do. Most applications on these Victorian streets are householder applications validated on existing and proposed plans across N15. Any Tottenham conservation area application is validated by Haringey Council, with Tottenham Hotspur Stadium the usual Tottenham reference point on the site plan.
Stroud Green (N4) — Victorian terraces defines Stroud Green, where victorian terraces set what a conservation area application can do. Most applications on these Victorian streets are householder applications validated on existing and proposed plans across N4. Any Stroud Green conservation area application is validated by Haringey Council, with Stroud Green Road the usual Stroud Green reference point on the site plan.
Hornsey (N8) — conservation area application work in Hornsey means edwardian terraces, victorian villas. Hornsey is Edwardian terraces, Victorian villas. Most applications on these Victorian streets are householder applications validated on existing and proposed plans throughout N8. Haringey Council decides the Hornsey application, and Hornsey High Street anchors the Hornsey location plan.
Wood Green (N22) — a conservation area application in Wood Green starts from edwardian terraces, post-war flats, and Wood Green reads as Edwardian terraces, post-war flats. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed in N22. Haringey Council assesses Wood Green conservation area applications against its own Wood Green character guidance, and the location plan we draw for Wood Green references The Mall Wood Green.
Crouch End (N8) — a conservation area application in Crouch End starts from edwardian terraces, victorian villas, and Crouch End reads as Edwardian terraces, village character. Most applications on these Victorian streets are householder applications validated on existing and proposed plans in N8. Haringey Council assesses Crouch End conservation area applications against its own Crouch End character guidance, and the location plan we draw for Crouch End references Crouch End Broadway.
Muswell Hill (Haringey) (N10) — a conservation area application in Muswell Hill (Haringey) starts from edwardian villas, 1930s semi-detached, and Muswell Hill (Haringey) reads as Edwardian villas and terraces. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed in N10. Haringey Council assesses Muswell Hill (Haringey) conservation area applications against its own Muswell Hill (Haringey) character guidance, and the location plan we draw for Muswell Hill (Haringey) references Muswell Hill Broadway.
Highgate (Haringey) (N6) — a conservation area application in Highgate (Haringey) starts from georgian villas, victorian terraces, and Highgate (Haringey) reads as Georgian and Victorian villages. Applications on Georgian stock here almost always need a heritage statement alongside the drawings in N6. Haringey Council assesses Highgate (Haringey) conservation area applications against its own Highgate (Haringey) character guidance, and the location plan we draw for Highgate (Haringey) references Highgate Wood.
Does Haringey planning policy restrict a conservation area application?
Prior approval, and how often Haringey refuses it: across 2023-24 to 2025-26 the council determined 287 larger householder cases. In 188 of them it confirmed no prior approval was needed at all; it approved 32; it refused 67. That refusal share of 23.3% sits just under the 24.9% recorded across all 33 boroughs, and thirteenth of the 27 with enough determinations to carry a rate. None of it applies inside the 29 conservation areas, where designation removes the permitted development right and the scheme reverts to a householder application. The householder application fee in England is £548; the fee for a larger householder prior approval is £249. Source: MHCLG live planning statistics.
Article 4 and your Haringey conservation area application: Borough-wide Article 4 for HMO conversions. At a N4 address that matters twice over, because Haringey Council applies the direction unevenly across Haringey — we read the Haringey policies map for the exact N4 address before quoting conservation area applications.
Haringey 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 conservation area application route in Haringey — construction, not postcode, sets what is achievable.
Who decides a conservation area application on the edge of Haringey?
Enfield — adjoining Haringey, with 22 conservation areas centred on EN1. A conservation area application on the far side of the Haringey line is determined by Enfield Council, so the Haringey quote for conservation area applications is checked against Enfield guidance before it is issued.
Waltham Forest — cross the Haringey boundary and Waltham Forest Council takes the conservation area application instead, applying 17 conservation areas of its own around E4. We re-price conservation area applications at the Haringey edge because Waltham Forest policy and Haringey policy rarely align on conservation area application depth.
Hackney — adjoining Haringey, with 29 conservation areas centred on E2. A conservation area application on the far side of the Haringey line is determined by Hackney Council, so the Haringey quote for conservation area applications is checked against Hackney guidance before it is issued.
Islington — the Islington boundary runs against Haringey, so a conservation area application a street from Haringey is decided by Islington Council instead. Islington runs 40 conservation areas across N1 and its neighbours, which is why conservation area applications priced for Haringey are re-checked against Islington policy whenever the Haringey address sits on that edge.
