Where the boundary comes from
For this guide the neighbourhood is the ground covered by three conservation areas in the London Borough of Hackney: Graham Road and Mapledene, Mare Street and Broadway Market, about 77.1 hectares together. Their designation years on the national record run from 1995 to 2000. The geology mapped beneath them is the same at every sample point, and the statistical areas around them hold a large pre-1900 stock alongside about a quarter of dwellings from 1945-1972.
Rather than describe streets, the sections below set out what each public record shows and what that changes about an inspection, from consent questions on listed houses to drainage on free-draining ground. Two council sources are used alongside the national datasets: Hackney's pages for the Broadway Market and Mare Street conservation areas, and its Article 4 page, read with a change-of-use direction that covers part of the study area. The rest of the borough is covered by the Hackney guide.
Records for the three conservation areas
Every statement below links to the public record it comes from; sources were re-checked on .
Boundaries and designation years
The Graham Road and Mapledene conservation area, reference CA3, is the largest part of the study area at about 56.4 hectares, and planning.data.gov.uk records only its designation year, 1997.
Mare Street, reference CA31 and about 16.7 hectares, carries a designation year of 2000, and Broadway Market, reference CA26 and about 4.0 hectares, a year of 1995.
Because only years are held for these designations, this page gives no day or month, and the conservation-area dataset is where the line around a given address is confirmed.
Hackney keeps a page for each of the two smaller areas, Broadway Market and Mare Street, and an owner planning alterations reads the relevant one before drawings are commissioned.
Article 4 polygons
None of the polygons that the national Article 4 dataset returns for the study area is titled as a conservation-area direction.
One that does state its purpose, A4D Non-residential to residential, covers 13.8% of the study area and is a change-of-use control rather than a heritage one.
Its record starts on 10 February 2022, so a flat formed from a shop, office or other non-residential space inside that polygon is checked for the planning permission or prior approval behind the conversion and the date it was granted.
Whether any direction removes householder rights at a particular address is checked on Hackney's Article 4 page before permitted development is assumed.
Listed entries
The NHLE dataset returns 53 list entries from within the boundary, 52 at Grade II and 1 at Grade II*.
That Grade II* entry is The New Lansdowne Club, and the national list has no Grade I entry inside the line.
A Grade II entry can describe a pair or a group as well as one house, so the entry text is read to see exactly what was listed and whether attached railings or walls are included.
For unlisted houses, conservation-area status still brings controls over demolition and some external changes, which is why the boundary records matter well beyond the 53 entries.
Gravel, clay and flood mapping
At every one of five sample points, Hackney Gravel Member deposits of sand and gravel rest on London Clay Formation bedrock, as BGS 1:50,000 geology maps it.
Gravel drains freely and is less affected by seasonal shrinkage than clay, but a leaking drain can wash fine material out of it, so the BGS mapping steers the inspection towards drainage condition and any settlement along old pipe runs.
Where footings are deep enough, or the gravel thin enough, to reach the clay beneath, trees and moisture change come back into play, and the map cannot show how thick the gravel is at one address.
Environment Agency mapping for planning, the Flood Map for Planning, leaves the whole study area outside Flood Zones 2 and 3.
Planning zones exclude the effect of defences and are not property-level, and surface water is not part of them, so a basement or lower ground floor is also checked through GOV.UK's flood risk lookup.
Housing in five statistical areas
The five LSOAs used here, each with 50% or more of its area within the study area, E01001749, E01001763, E01001816, E01001819 and E01001839, contain about 4,190 dwellings according to 2025 Council Tax property statistics from the VOA, which give counts to the nearest 10.
The build-period figures date 43.2% of those dwellings to before 1900, 25.5% to 1945-1972, 14.6% to 2000 or later, 8.6% to 1973-1999, 4.8% to 1900-1918 and 2.1% to 1919-1939, the remaining 0.5% being of unknown date.
In the property-type table flats and maisonettes come to 76.6%, terraced houses 19.1%, semi-detached houses 2.6%, and bungalows and detached houses 0.5% each.
Only 6.7% of the dwellings sit in bands F to H, and the largest band in the VOA counts is C, at 29.8%.
The LSOAs only approximate the conservation areas, yet because flats outnumber houses while pre-1900 dwellings form the largest age group in the VOA tables, a flat inside a converted older house is a likely case, and the lease plan and the split of the original structure are checked early.
Area guides by type of instruction
Each guide below deals with one instruction type for homes in and near these conservation areas, with the practice-wide pages explaining the service in general.
Neighbouring guides
Dalston, De Beauvoir, Haggerston and Hoxton have guides setting out comparable records for neighbouring districts, and the Hackney guide draws the borough together.
Owners' and buyers' questions for E8's conservation areas
When were the three conservation areas designated?
The planning.data.gov.uk records give years only: 1995 for Broadway Market, 1997 for Graham Road and Mapledene and 2000 for Mare Street. Because no day or month is recorded, Hackney's own conservation pages are the place to look for fuller designation details.
Do Article 4 directions limit changes to houses in these streets?
No polygon in the national Article 4 dataset for this area is titled as a conservation-area direction; one named A4D Non-residential to residential, a change-of-use control, covers 13.8% of the study area. Check Hackney's Article 4 page for the address before relying on permitted development.
Is there a Grade I building inside the boundary?
There is not. The NHLE data returns 53 list entries, 52 at Grade II and one at Grade II*, The New Lansdowne Club. Grade II status still means consent is needed for changes that would alter a building's special interest, inside or out.
Does gravel under the area make subsidence unlikely?
Not on its own. BGS mapping at 1:50,000 scale puts Hackney Gravel over London Clay at all five sample points, and gravel resists seasonal shrinkage, but leaking drains can wash it out and deeper foundations may reach the clay. Cracks are judged at the property, not from the map.
How old are most homes around the conservation areas?
In the five LSOAs used here, the VOA 2025 figures date 43.2% of about 4,190 dwellings to before 1900 and 25.5% to 1945-1972. Flats make up 76.6%, so the age of the building and the terms of the lease usually need to be read together.
What should be sent before an inspection of a pre-1900 house?
Drawings or planning references for loft, rear or basement work, the dates of re-roofing or rewiring, invoices for drainage repairs and notes of cracks that have been filled. Those records show which parts of a house of that age have already been altered and which are likely to be original.
How we work on an instruction
Hampstead Chartered Surveyors is a RICS-regulated firm (RICS Regulated Firm No. 923064) working from its registered Hampstead NW3 office. The firm does not claim premises, staff or completed instructions in an individual locality, and it does not treat a neighbourhood name as evidence about a particular building.
An instruction starts with the full address, the decision the client faces and the documents already available, such as leases, drawings, notices or earlier reports. The scope, fee and inspection date are confirmed in writing only after that review, and access to roofs, lofts, basements or common parts is agreed before the visit.
Reports include RICS Level 2 and Level 3 home surveys, building and defect investigations, party wall appointments, reinstatement cost assessments, contract administration and schedules of condition. Each report records what was inspected, what could not be seen and what further investigation the evidence supports.
Public datasets such as the conservation-area register, the National Heritage List for England, British Geological Survey mapping, the Environment Agency flood map and Valuation Office Agency housing statistics describe areas rather than individual properties. They frame questions before an inspection; they never replace it.
