House Extension East Sheen SW14 Under Five Separate Designations
Most London suburbs have one conservation area, or none. East Sheen has five, and they do not share a boundary or a rulebook.
The London Borough of Richmond upon Thames designates and numbers them individually: Christchurch Road is number 13, Model Cottages number 34, East Sheen Avenue number 52, Sheen Lane number 64, and Sheen Common Drive number 69. Each has its own statement, its own designation date and its own account of what makes it worth protecting. Two of them adjoin Christchurch Road directly, one to the east and one to the west.
So the first question about a house extension in East Sheen is not what you want to build. It is which boundary your address falls inside, because that decides everything that follows.
Two houses on adjoining roads can sit under different designations, with different appraisals and different expectations about materials and boundary treatment. Neither owner would know from looking.
Design And Build works across SW14 on the Edwardian and interwar houses that make up most of the suburb, from the streets below Upper Richmond Road up the slope toward Richmond Park. Design, engineering, surveying and the trades all sit in-house, on our own payroll. What follows is what the council actually says about these streets, and what that means for a scheme.

Five boundaries decide a house extension East Sheen scheme
Christchurch Road, designated in 1969 and the oldest ground
Christchurch Road, conservation area 13, was designated on 14 January 1969, among the first in the borough. It has been extended three times since, most recently in May 2002.
The council places it precisely: within East Sheen, contained by Richmond Park to the south and later suburban development to the north, adjoining Sheen Common Drive to the west and Sheen Lane to the east.
Its history explains the mix. The medieval hamlet of East Sheen was centred on two points, Milestone Green down the hill and Christchurch Road near the old Plough public house up it. An important cluster of eighteenth-century buildings survives here, including a listed house dating from 1740. After Mortlake Station opened in 1846, large Victorian villas in their own grounds followed.
The council’s own study describes the result as a complete mix, running from tiny terraced cottages to large villas in generous gardens, with two public houses and no shops. That variety matters, because a scheme judged against its immediate neighbours is judged differently on each part of the street.
It also stands on the slope north of Richmond Park, which affects both the outlook from the upper streets and the way an addition at the back reads from neighbouring gardens. Levels are worth establishing at survey rather than assuming from a plan.
East Sheen Avenue and the meadowland it replaced
East Sheen Avenue, conservation area 52, was designated on 14 June 1988 and extended in May 2002. It runs the length of the avenue between Upper Richmond Road and Vicarage Road.
The council records that it was developed as a distinctive part of the suburban expansion of East Sheen, from the late nineteenth century into the Edwardian period, on meadowland that had formed part of the Palewell Estate. All Saints Church was completed in 1929 and reopened after a fire in 1967.
What the designation protects is described plainly: a peaceful residential area of predominantly large semi-detached houses lining a wide avenue of mature trees, on the gentle slope between a busy road and a quiet one. The trees are part of what is being protected, not a backdrop to it.
Sheen Common Drive, where the verges are part of the protection
Sheen Common Drive, conservation area 69, was designated on 13 January 2004 and extended in November 2005. It lies between Upper Richmond Road and Sheen Common.
Its core is an estate of detached two-storey houses built between 1925 and 1932, which the council calls a good example of a planned housing estate from the 1920s. The area is triangular, bounded by the backs of Upper Richmond Road houses on one side, East Sheen Common on another, and the rears of Stanley Road and Christchurch Road properties on the third.
The council then names the materials, which is unusual and useful: red plain roof tiles, red and brown bricks, pebbledash, render, tile hanging, casement windows and half-timbered first floors. A scheme here answers that palette or explains itself.
And it protects the landscaping. The statement singles out the well-maintained landscaped verges between the footways and the road, noting that verges were a feature of many estates of this period but that few survive. On one street they are laid in red brick paving with tree planting instead. Anything that removes or crosses them is a planning matter.
Planning permission East Sheen SW14 turns on which boundary applies
Rights withdrawn on the public-facing elevation
Outside a conservation area, permitted development rights let a homeowner carry out defined work without applying at all. Inside one, that position narrows, and in parts of East Sheen it narrows further still.
The council’s conservation area study covering Christchurch Road and East Sheen Avenue refers to Article 4(2) Directions implemented as part of that work. What an Article 4 direction does is take away rights a homeowner would normally have without asking. Where one is in place, work to the front of a house needs a full application even though the same work elsewhere would not.
This is worth being exact about, because published sources get it wrong. At least one planning site states that no Article 4 direction is in force in this borough. That is incorrect, and an owner relying on it would price a scheme on rights they do not have. We check the direction schedule against the address.
Designation also brings two controls that have nothing to do with extensions. Demolition of unlisted buildings requires consent, and so does felling or lopping trees above a certain size. On streets the council values for their mature planting, that is not a technicality.
Front boundary walls, and why they reach the council
A recent East Sheen application shows how far the designation reaches. The proposal was to take down a timber fence at the front of a house and replace it with a brick wall.
Nothing about the house itself was changing. The scheme still went to the council, because inside a conservation area the boundary treatment forms part of the street scene the designation exists to protect.
The same logic governs windows, roof coverings, render, and anything visible from the road. Applications from these streets in a recent period included replacing timber box sashes and front casement windows, and altering roofs with rooflights to the front slope. Our architects draw the front elevation to the standard the council expects, and reserve the ambition for the back.
Builders East Sheen: what eight weeks with Richmond involves
Richmond determines a householder application in eight weeks from validation. That is the statutory period, and it starts only once the submission is complete.
Around forty applications were lodged in the East Sheen ward in a recent period, which gives a fair picture of what the council sees from these streets: work at the back and in the roof, ground floor additions replacing garages, bay work with roof lanterns, and detached garden buildings.
The depths being sought are not modest either. One recent scheme in the ward went in at six metres from the original rear wall, with an eaves height of two and a half metres and an overall height of three point two. That is the upper end of what the larger householder route allows, and it is being asked for and granted on these streets.
Some of that goes in as a full application and some as a certificate. Where a scheme falls within permitted development and the address is outside a designation, a lawful development certificate confirms the position in writing. One East Sheen owner recently used exactly that route for roof work. It costs less than a full application and gives a future buyer a clear answer.
Two things owners routinely run together. Planning permission answers whether a scheme may be built; Building Regulations approval answers whether it is built properly. They are different consents with different procedures, and clearing one leaves the other untouched. Neighbouring walls bring a third obligation again, under the Party Wall etc. Act 1996.
House renovation East Sheen on a suburb built 1896 to 1935
The council gives the dates for the suburb, and they are narrower than most people assume.
Intensive development began in 1896 with the sale of the Palewell Estate. Other estates followed and building continued until 1914. After a pause for the First World War it resumed, ending around 1935. The area consists mainly of detached and semi-detached houses from 1900 to 1935, characterised by distinct groups of similar properties, with cohesion coming from the linear run of buildings at a similar height.
Two older layers sit inside that. The eighteenth-century group around Christchurch Road, and the Model Cottages of 1853 — paired two-storey villas with shallow hipped slate roofs, central stacks and long planted front gardens, which the council contrasts with the taller Victorian terraces nearby.
Each layer fails differently. Edwardian houses of this type usually need the services renewed entirely and the roof coverings assessed. Interwar houses bring solid or early cavity walls where the insulation strategy has to be chosen carefully. The eighteenth-century stock needs a heritage-led approach from the first survey. Our structural engineers read the building type before the checklist, and interior design joins while the layout can still move.
Area We Cover
Four appointments, or one construction company East Sheen retains
The usual route is an architect, then an engineer, then a builder, then a party wall surveyor. Four appointments, four contracts, and four sets of assumptions about which designation applies.
In a district with five conservation areas and Article 4 directions on some of them, that is where delay comes from. An architect who assumes permitted development, on a street where it has been withdrawn, produces drawings that cannot be built.
We hold the whole sequence instead. The measured survey, the drawings, the heritage case, the engineering and the construction run through a single team, a single agreement and a single price. Party wall notices go out from our own surveyors. Every trade on site is on our books, so the designation confirmed at survey is the one that governs what actually gets built.
The council can date your house from the junction it stands beside
The Sheen Lane conservation area statement contains something we have not seen from any other London borough. It dates the street in sections.
Properties in one road date mainly from 1901 to 1905. Between the old coach house and a named junction, the west side is mainly Edwardian while the east side was built between 1913 and 1914. From that junction to the park gate, properties generally date from 1923 to 1927. North of another junction the houses are pre-war; south of it they run from 1923 to 1935. A few properties from 1950 to 1980 were included anyway, because of their position in the street scene.
The coach house itself has fabric from 1788, when it served a house that no longer stands.
The lane it stands on is older still. In medieval times the main route east to west ran along what is now Lower Richmond Road, connecting the ferry at Putney, the Archbishop’s manor at Mortlake and the royal palace at Richmond, while Sheen Lane formed part of the road south to Kingston. Its line still follows the field boundaries it was laid along.
For a homeowner that level of detail is genuinely useful, because it tells you what an officer already knows about your building before you apply. For a contractor it sets the standard: if the council can be that precise, a heritage statement that speaks in generalities will not do.
One more point of precision, since it confuses people. There are two Sheen Lane conservation areas. Number 64 is in East Sheen, north of the park gate. Number 70 covers the commercial stretch toward Mortlake, and is a different designation with different boundaries. An address on Sheen Lane may sit in either, or in neither.
We start with the boundary map, not the tape measure
Send the address, and the position comes back in writing before anyone quotes.
Which of the five conservation areas covers it, and when that area was designated. Whether an Article 4 direction applies to the elevation. Whether the building is listed or of townscape merit. What permitted development survives, if any. And what has been approved recently on the same road, which is usually the best guide to what an officer will accept next.
Our work covers East Sheen and the wider SW14 postcode — Christchurch Road, Sheen Lane, East Sheen Avenue, Sheen Common Drive, Fife Road, Deanhill Road, Clare Lawn Avenue, Palewell and the streets between Upper Richmond Road and the park — together with Richmond, Barnes, Putney, Chiswick, Kingston, Wimbledon, Fulham and the wider south west London area. Richmond’s borough-wide controls, including the directions covering anything below the ground floor, are set out on our Richmond page.
Surveys cost nothing. In SW14 the first answer is which of the five you are in.
