A station circle across a borough line
The circle crosses a borough line. The seven LSOAs used for the VOA figures, each at least half inside it, belong partly to Lewisham and partly to Southwark, and Southwark's own description places its Honor Oak Rise conservation area on the borough's southern boundary, where Southwark meets the Honor Oak Park area in the London Borough of Lewisham. That conservation area is the only one the circle overlaps in the national dataset, by about 4.7 hectares, so it is treated here as context rather than as the subject.
Lewisham's Forest Hill conservation area has its own guide and is not described here, and the rest of the borough is in the Lewisham guide.
Records within 750 metres of the station
Every statement below links to the public record it comes from; sources were re-checked on .
Honor Oak Rise, the one conservation area overlapping the circle in national data
Southwark's list of conservation areas states that Honor Oak Rise was made a conservation area on 29 September 1985, and the planning.data.gov.uk record gives the same day as its record start date.
About 4.7 hectares of it, 2.7% of the circle, fall within 750 metres of the station on that record, and no other conservation area overlaps the circle in the national dataset.
Southwark describes 19th century out-of-town homes that grew among farmland and woodland and were later surrounded by suburban housing, beside a historic area of semi-natural woodland on One Tree Hill.
On the Lewisham side, the council's maps of conservation areas include no area named after Honor Oak, so for most addresses in the circle the heritage questions turn on listing and on the Article 4 records below.
Seven Article 4 polygons, one of them large
Seven polygons from the Article 4 dataset touch the circle, and much the largest is the Small HMO Northern Extension, which covers 67.3% of it.
Its title points to houses in multiple occupation, so the use of a house by several sharers, rather than its repair or appearance, is what the record bears on.
Smaller polygons are titled Honor Oak & Brockley Rise Local Centre at 0.4%, Crofton Park Local Centre and Mahlam Road LSIS at 0.1% each, and Railway Arches, recorded twice as 7010003613 and 7010006913, at 0.1% each.
A further 0.3% lies under the Forest Hill Article 4(3) Direction, whose title ties it to the neighbouring designation covered by its own guide.
Lewisham's page on Article 4 directions in conservation areas explains that those directions apply only to houses used as single dwellings, and that commercial properties and flats do not have permitted development rights.
Southwark's Article 4 page makes the point that a direction never reaches back to past development, so the date of a change of use or an alteration is set against the date of the direction, which none of the seven national records gives and which therefore comes from the council.
Fifteen Grade II entries
Fifteen list entries lie within 750 metres of the station in the NHLE layer, all at Grade II, while Grade II* and Grade I entries, scheduled monuments and registered parks and gardens are all absent from the circle.
Spread over 176.7 hectares, fifteen entries make listing the exception, but the NHLE is still searched by address before a scheme is drawn, since consent for a listed building reaches its interior too.
London Clay at every sample point
Every one of the five sample points inside the circle sits on London Clay Formation, a clay and silt, with nothing superficial mapped above it, in BGS 1:50,000 data.
Exposed clay loses volume as it dries in a hot summer and regains it through a wet winter, so for a terraced house the inspection compares any movement in a bay or rear addition with the main walls, and the BGS viewer is no substitute for looking at the trees and drains nearby.
Southwark's note that Honor Oak Rise sits beside semi-natural woodland on One Tree Hill makes the distance from large trees a particular question for houses on that side of the circle.
In Environment Agency planning flood mapping, river flooding puts Flood Zone 3 over 0.1% of the circle, and Flood Zone 2 rounds to 0.0%.
Surface water and defences are both left out of those zones, which is why a lower-ground flat or a garden that falls towards the back door also gets a postcode search on the long-term flood risk service, which gives the risk for an area rather than a specific property.
Housing across seven LSOAs
Seven LSOAs fall half or more within the circle, five in Lewisham and two in Southwark, and the 2025 Council Tax stock of properties published by the VOA counts about 5,200 dwellings across them, each figure rounded to the nearest 10.
The age table puts 44.4% of dwellings before 1900, the biggest single period, and 1919-1939 accounts for 20.6%, more than either 1900-1918 at 12.3% or 1945-1972 at 10.6%, with 6.5% from 2000 onwards, 4.6% from 1973-1999 and 1.5% undated.
Flats and maisonettes, at 44.8%, only just outnumber terraced houses at 41.3% in the property types, with semi-detached houses at 10.4%, detached at 2.1% and bungalows at 0.6%.
Band D is the largest at 37.7% in the VOA bands, followed by C at 32.1% and B at 14.0%, while F to H together come to 3.7%.
With flats and terraced houses almost level and an interwar layer beside the pre-1900 one, the age of a building and whether it has been divided are established from its own papers, since the VOA tables describe only the area.
Area guides for each instruction
One guide per type of instruction appears in the first list, written for homes in and around the station circle, and the second list holds the firm-wide pages on each service.
Surrounding districts and the borough guide
For Lewisham as a whole, see the Lewisham guide. Guides for Forest Hill, Brockley, Catford and Peckham each rest on their own study areas, and elsewhere in Lewisham the Telegraph Hill guide follows a single conservation area.
Buyers' and owners' questions across the circle
Is the area round the station a conservation area?
Mostly not. In the national dataset, the only conservation area the 750-metre circle overlaps is Southwark's Honor Oak Rise, about 4.7 hectares or 2.7% of it. Check the exact address against the mapped boundary before planning external work.
What does the Small HMO direction mean for a buyer?
The Small HMO Northern Extension record covers 67.3% of the circle. A buyer who intends to rent rooms to several unrelated sharers confirms with the council whether planning permission is needed before exchange, since that change of use is what the title addresses.
Do flats here have permitted development rights?
Lewisham's Article 4 page states that flats and commercial properties do not have them, so works to a flat that count as development need an application. The lease says separately what the leaseholder may alter.
Which stations are within reach of the circle?
Honor Oak Park Rail Station is at its centre on the NaPTAN dataset, Crofton Park Rail Station lies about 100 metres beyond its edge and Forest Hill about 550 metres beyond it, with Catford roughly 720 metres beyond it.
Why does the clay matter for a terraced house?
BGS mapping records London Clay, with no superficial deposit over it, at every one of the five sample points, and clay moves as it dries and rewets, most near trees. Bays and rear additions are where that tends to show, though drains and past alterations are ruled in or out before a cause is given.
What is worth having ready before an inspection?
For a flat, the lease and plan, recent service-charge accounts and the freeholder's record of roof and external repairs; for a house, papers for any loft, rear or basement work and any permission obtained for letting rooms. Those records show which changes were approved and when.
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.
