De Beauvoir and Stoke Newington: 29 Hackney heritage areas
Hackney has 29 conservation areas, and along the Lea a second constraint sits on top of them. Environment Agency mapping places 0.81 sq km of the borough, 4.24% of its 19.04 sq km, in Flood Zone 3; in E9 the figure reaches 14.5% of postcode units. Zone 2 or Zone 3 means the application needs a Flood Risk Assessment, whatever the character appraisal has to say about shopfronts and slate.
The national register records 44 conservation areas covering about 699 hectares, 36 of them dated, the earliest from 1969. Inside them Class B roof enlargement does not apply at all, which is why Hackney’s Datahub set records 892 mansard applications.

Sources: conservation areas from the planning.data.gov.uk register, retrieved 1 September 2026, with hectares computed from the published boundaries; Datahub rows from the Planning London Datahub, retrieved 15 August 2026, phrase-matched and comparable within Hackney only; decision figures from MHCLG PS1 and PS2, twelve quarters to March 2026. Eight Hackney designations carry no date in the register, which is a gap in the data rather than in the designation.
Can I check whether my Hackney street is inside a conservation area?
You can. The map plots the Hackney conservation areas recorded on the national register, and a postcode typed into it is matched against those shapes locally, in the browser, with nothing sent anywhere. What it cannot do is arbitrate a marginal case. The boundaries are drawn from simplified polygons, so a house at the very edge of one may render just inside or just outside; the council’s published boundary is what decides that, and it is a five-minute question to ask before it becomes an expensive one.
Hackney never stopped designating. The oldest date the register holds for the borough is 1969 and the newest is 2021, and the 699 hectares between those two dates were added in stages across half a century rather than laid down in one policy push. Graham Road and Mapledene is the largest single area at 56 hectares; Newington Green (North), at 0.7, is the smallest. The paperwork is uneven in a way that shows up on real jobs. Eight areas have no designation date recorded at all, and six carry no council document at all, so there is nothing filed nationally to argue from — you and the case officer end up reading the same terrace with no agreed text between you, and the design justification has to do more work. Article 4 is the other blank. Hackney has not filed its directions to the national register, so nothing is drawn for them here, and that absence says nothing about whether directions apply to your street. Ask the council.
The shapes, names and hectare figures above come from planning.data.gov.uk: the conservation-area dataset and the article-4-direction-area dataset, both retrieved 15 August 2026 and re-checked two weeks later, on 1 September 2026.

Answers for Hackney
How many conservation areas does Hackney have?
Twenty-nine conservation areas are designated across the borough, De Beauvoir Town, Stoke Newington, Dalston Lane, Hackney Central and Clapton among them. On the VOA council tax stock count at 31 March 2025, 29.4% of the 120,680 dwellings here predate 1900, which is why designation covers so much of the housing rather than a handful of streets.
What changes need planning in a Hackney 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 Hackney?
Yes, and it has to do real work. The statement must take the published character appraisal for the specific area seriously, name the heritage assets your proposal touches, and set out why the design leaves that character better or no worse than it found it. A page of generalities draws the same response from a conservation officer as no statement at all. It is drafted here alongside the drawings rather than bolted on at the end.
Can I have a roof extension or mansard in a Hackney conservation area?
Rear mansards and rear dormers do get consent here, where the new roof form answers the terrace around it — in De Beauvoir Town and Clapton as much as in comparable Islington or Southwark streets. Dormers on a principal elevation are close to automatically refused. Designation is not itself a bar: the borough issued 220 decisions on listed building consent for alteration or extension across the 2023-24 to 2025-26 returns, granting 191. What settles a case is whether the new roofscape reads as part of the old one.
How long does conservation area approval take in Hackney?
A householder application carries an 8 week statutory determination clock, and the conservation officer's consultation usually adds 2 to 3 weeks on top of it. In practice the decision lands 11 to 14 weeks after validation. Agreed extensions of time are routine: on 1,693 of the 3,843 applications determined across 2023-24 to 2025-26, the council recorded one, so it is worth having the agreed date in writing rather than trusting the statutory clock.

Which Hackney postcodes does this conservation area application service cover?
The postcode districts of this borough that we work in, the dominant stock in each and the authority validating an application there. Charges in the fee column are set by government for 2026 and apply throughout England.
Postcode
Area
Dominant stock
What it means for a conservation area application
N16
Stoke Newington / Stamford Hill
Georgian and Victorian terraces
Stoke Newington and Stamford Hill share N16, which crosses into Islington in places. The proposals map, rather than the postcode, decides whether this borough determines the application.
E5
Clapton
Victorian terraces, mansion blocks
E5 covers Clapton only; Hackney Council handles the conservation area application.
E8
Hackney Central / Dalston / London Fields
Victorian terraces, post-war flats
E8 covers Hackney Central / Dalston / London Fields only; Hackney Council handles the conservation area application.
E9
Homerton / Hackney Wick
Victorian terraces, post-war estates
E9, covering Homerton and Hackney Wick, lies wholly inside the borough, so every application from an E9 address is validated here — though 14.5% of E9 postcode units fall in Flood Zone 3, so a Flood Risk Assessment often has to be prepared alongside the heritage material.
EC2A
Shoreditch
Warehouse conversions, modern infill
The Shoreditch end of EC2A is split between this borough and the City of London Corporation, with the boundary running mid-street in places, so the determining authority is confirmed from the address first.
N1
Islington / Hoxton
Georgian and early Victorian terraces
N1 spans Hoxton and Islington, and either council may turn out to be the one determining your application, so an N1 address gets tested against both sets of policies at the outset.
N4
Finsbury Park / Stroud Green
Victorian terraces, post-war estates
N4, around Finsbury Park and Stroud Green, is shared between Haringey, Islington and Hackney, so an N4 address has to be tested against all three sets of policies before an application is drafted.
E2
Bethnal Green
Warehouse conversions, modern infill
E2 around Bethnal Green sits mostly in Tower Hamlets with a Hackney edge; which council decides an E2 application follows the boundary, not the postcode.
What changes about a conservation area application in each part of Hackney?
Pitch, wall thickness and plot depth alter terrace by terrace here, and inside a conservation area such details decide whether a scheme is approvable at all.
De Beauvoir Town (N1) — Georgian and early Victorian conservation area defines De Beauvoir Town, where georgian villas and terraces set what a conservation area application can do. Applications on Georgian stock here almost always need a heritage statement alongside the drawings across N1. Any De Beauvoir Town conservation area application is validated by Hackney Council, with De Beauvoir Square the usual De Beauvoir Town reference point on the site plan.
Stamford Hill (N16) — conservation area application work in Stamford Hill means victorian villas, edwardian terraces. Stamford Hill is Victorian villas, Edwardian terraces. Most applications on these Victorian streets are householder applications validated on existing and proposed plans throughout N16. Hackney Council decides the Stamford Hill application, and Stamford Hill anchors the Stamford Hill location plan.
Dalston (E8) — Victorian terraces, vibrant high street defines Dalston, where victorian terraces, post-war flats set what a conservation area application can do. Most applications on these Victorian streets are householder applications validated on existing and proposed plans across E8. Any Dalston conservation area application is validated by Hackney Council, with Ridley Road Market the usual Dalston reference point on the site plan.
Stoke Newington (N16) — a conservation area application in Stoke Newington starts from victorian terraces, georgian fragments, and Stoke Newington reads as Victorian terraces, village character. Applications on Georgian stock here almost always need a heritage statement alongside the drawings in N16. Hackney Council assesses Stoke Newington conservation area applications against its own Stoke Newington character guidance, and the location plan we draw for Stoke Newington references Clissold Park.
Shoreditch (E1, E2, EC2A) — Victorian warehouse conversions, creative industries defines Shoreditch, where warehouse conversions, modern infill set what a conservation area application can do. Modern housing here is usually condition-bound across E1. Any Shoreditch conservation area application is validated by Hackney Council, with Boxpark the usual Shoreditch reference point on the site plan.
Hackney Central (E8) — a conservation area application in Hackney Central starts from victorian terraces, post-war estates, new-build, and Hackney Central reads as regenerated centre, Victorian terraces around. Most applications on these Victorian streets are householder applications validated on existing and proposed plans in E8. Hackney Council assesses Hackney Central conservation area applications against its own Hackney Central character guidance, and the location plan we draw for Hackney Central references Hackney Empire.
London Fields (E8) — Victorian terraces around the park defines London Fields, 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 E8. Any London Fields conservation area application is validated by Hackney Council, with London Fields park the usual London Fields reference point on the site plan.
Does Hackney planning policy restrict a conservation area application?
What designation changes: permitted development cannot be relied on inside any of the 29 conservation areas, which turns a 6 week prior approval into a full householder application determined in 8 weeks. The fee for a larger householder prior approval is £249. The householder application fee in England is £548. On the last three years of MHCLG returns the council granted 1,097 of 1,350 householder decisions, 81.3% against 83.0% for the 33 boroughs pooled, and withdrawal is a common ending here: 476 applications withdrawn against 4,250 received, 11.2%, the fourth-highest share in London against a pooled 6.9%.
What Article 4 removes near Hackney: Article 4 Direction covers HMO conversions borough-wide and office-to-residential in specific commercial zones. Before pricing a conservation area application we check whether the N16 address is inside the mapped area, because Hackney Council draws the Hackney boundary street by street rather than across the whole of Hackney.
Hackney housing stock: Victorian terraces dominate; large post-war estates around Hackney Wick; Georgian fragments in De Beauvoir and Stoke Newington; new-build around the Olympic Park. Young demographic; high design-quality bar in planning; mansards routinely approved in rear-of-terrace positions within conservation areas following the Hackney design guide. Read that before choosing a conservation area application route in Hackney — construction, not postcode, sets what is achievable.
Which neighbouring authorities border Hackney?
Haringey — adjoining Hackney, with 29 conservation areas centred on N4. A conservation area application on the far side of the Hackney line is determined by Haringey Council, so the Hackney quote for conservation area applications is checked against Haringey guidance before it is issued.
Waltham Forest — cross the Hackney 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 Hackney edge because Waltham Forest policy and Hackney policy rarely align on conservation area application depth.
Newham — adjoining Hackney, with 10 conservation areas centred on E6. A conservation area application on the far side of the Hackney line is determined by Newham Council, so the Hackney quote for conservation area applications is checked against Newham guidance before it is issued.
Tower Hamlets — cross the Hackney boundary and Tower Hamlets Council takes the conservation area application instead, applying 58 conservation areas of its own around E1. We re-price conservation area applications at the Hackney edge because Tower Hamlets policy and Hackney policy rarely align on conservation area application depth.
