Two designations split by a river and a railway
Two Lewisham conservation areas make up the study area: Ladywell, about 10.1 hectares and designated in 2010, and St Marys, about 7.2 hectares, which the national record dates to 1976. The council's appraisal places the first directly west of the Mid-Kent Line and the River Ravensbourne, with Lewisham High Street and the St Mary's area on the far side, so the river and the railway run between the two. The local station stands inside the study area on the NaPTAN record, while Lewisham's DLR and rail stations lie 480 and 520 metres beyond its edge.
Much of the character is recorded by the council rather than nationally: one builder's almost complete Victorian estate on the slopes of Hilly Fields, a shopping street that grew up beside the station and an Article 4 direction protecting the details of houses in single-dwelling use. The Lewisham guide covers the borough beyond.

Designations and the 2010 appraisal
The Ladywell conservation area record, reference LEWCA26, covers about 10.1 hectares, and planning.data.gov.uk holds only the year of designation, 2010.
The St Marys record, LEWCA16 and about 7.2 hectares, likewise gives a year alone, 1976.
Lewisham's character appraisal, adopted by the Mayor and Cabinet in March 2010, explains that reviewing and extending the St Mary's area showed the need to appraise these streets in their own right, after which the council was repeatedly asked to designate them.
Its core is the work of the local builder Samuel Jerrard, who through the 1880s and 1890s built up long stretches of Vicars Hill, Algernon Road, Algiers Road, Ermine Road and Embleton Road, and the council's conservation-area page says that development survives nearly complete.
List entries, the station among them
Eleven list entries fall within the study area in the NHLE dataset, nine at Grade II and two at Grade II*.
The Grade II* pair are the Church of St Mary the Virgin and St Mary's Vicarage.
The appraisal describes the station as a Grade II listed building first constructed in 1857 for the Mid Kent Railway, a low single-storey building with a lattice-girder footbridge.
With only eleven entries across both areas, most of Jerrard's houses are protected by the conservation area rather than by listing, and the NHLE record for an address is what settles the question.
The Article 4 direction and its reach
Two polygons in the national Article 4 dataset are titled for the conservation areas: Ladywell's direction, covering 45.1% of the study area, and St Mary's, covering 5.2%.
The Ladywell conservation area accounts for about 10.1 of the 17.3 hectares, yet its direction polygon covers a smaller share, so the direction's own map, not the conservation-area line, decides whether a house is caught.
Lewisham's Article 4 page says its directions apply only to houses used as a single dwelling, and that flats and commercial properties have no permitted development rights to begin with.
Under a direction, the page lists changes visible from public viewpoints that need permission, among them windows, doors and chimneys, roof alterations, porches, hard surfacing, gates, walls and fences, and painting the outside of a house.
The appraisal shows why: original timber sashes and doors had been replaced in large numbers, and the railings on Jerrard's low walls went for the war effort in the 1940s.
Two further polygons are titled for town centres, Ladywell Local Centre at 1.4% and Lewisham Major Centre at 1.6%, and a Small HMO Northern Extension direction spans the whole study area, which matters before a house is let to sharers.
River zones, alluvium and Lambeth Group
The Environment Agency's Flood Map for Planning places 17.0% of the study area in Flood Zone 2 and 13.3% in Flood Zone 3, all of it from rivers.
Bedrock at all five sample points is Lambeth Group clay, silt and sand on the BGS 1:50,000 map, and the superficial layer adds Alluvium at one point and Kempton Park Gravel Member sand and gravel at another, leaving three without cover.
Alluvium is mapped as a mix of clay, silt, sand and gravel that can vary over short distances, so a house on the low ground by the Ravensbourne, which the appraisal places between the two conservation areas, is checked for settlement as well as for any flooding history.
Ladywell Road, Gillian Street and the lower part of Algernon Road lie on flat ground at the foot of the hill while the streets above fall steeply towards the river, the appraisal notes.
The long-term flood risk service adds surface water, reservoirs and, where data exists, groundwater for an area, though by its own account it does not say how likely an individual property is to flood.
Housing in one statistical area
No LSOA has half its area inside a study area this small, so the figures use the one with at least a quarter inside, E01003279, Lewisham 011D, which holds about 740 dwellings in the VOA's 2025 stock of properties, rounded to the nearest 10.
In the VOA age breakdown, 60.8% of those dwellings predate 1900, 14.9% date from 1919-1939, 10.8% from 2000 onwards, 6.8% from 1945-1972 and 1.4% from 1900-1918, with too few from 1973-1999 to register in the rounded counts and 2.7% undated.
Terraced houses at 44.6% narrowly outnumber flats and maisonettes at 43.2%, with semi-detached houses at 12.2% and detached at 1.4%, in the type table.
Bands C and D are the largest at 32.4% and 29.7%, and just 2.7% fall in bands F to H, on the VOA banding figures.
The appraisal criticises conversions into flats that eroded the character of some Algernon Road buildings, so the buyer of a flat in a divided Victorian house asks for the conversion's planning and building-control records as well as the lease.
Area guides and the services behind them
This area's guide for each type of instruction is in the first list, and the second points to the firm-wide page describing that service in general.
Guides on either side
The Lewisham guide covers the borough. Brockley, Catford and Forest Hill have guides of their own, Hither Green has one in the same borough, and Nunhead has one across the boundary in Southwark.
Questions on the two conservation areas
Does the Article 4 direction reach every house in the conservation area?
Not necessarily. In the national dataset the direction polygon covers 45.1% of the study area while the conservation area makes up about 10.1 of its 17.3 hectares, so the direction's map is checked for the address.
Which changes stop being automatic under the direction?
Lewisham's Article 4 page gives examples visible from public viewpoints, from windows, doors and chimneys to porches, hard surfacing, boundary walls and exterior repainting. Permission is not ruled out; those changes simply need an application, and only houses in use as a single dwelling are affected.
How much of the area falls in a river flood zone?
On the Environment Agency's planning map, 17.0% of the study area is in Flood Zone 2 and 13.3% in Flood Zone 3, all from rivers. Those zones leave out defences and surface water, so the long-term flood risk service is checked for the address as well.
Who built the Victorian houses on Vicars Hill and Algernon Road?
Largely Samuel Jerrard, a Lewisham builder, through the 1880s and 1890s, according to the council's appraisal, which describes semis and short terraces alternating yellow stock and red brick fronts, with stucco, stone and terracotta details.
Is the railway station a listed building?
Yes. The council's appraisal describes it as Grade II listed and first built in 1857 for the Mid Kent Railway, and in the NHLE dataset it is one of 11 list entries in the study area.
What is worth gathering before buying a converted flat here?
The lease and its plan, the conversion's planning and building-control records, consents for any external changes and recent service-charge accounts. Flats are 43.2% of dwellings in the LSOA used and 60.8% of its stock predates 1900; the VOA tables do not show how many of those flats are in converted houses, but the council's appraisal records conversions into flats on Algernon Road.
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.
