L-shaped wraparound drawings for Richmond upon Thames — a full-width rear extension married to the side-return infill so the whole ground floor opens up, drawn to Richmond upon Thames Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Richmond upon Thames Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. The borough's exceptional conservation coverage means design detail and materials are scrutinised closely, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Richmond upon Thames carries at least one Article 4 direction, and conservation areas including Richmond Green, Twickenham Riverside and Kew Green remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Richmond upon Thames is determined against an 8-week statutory target.
Richmond (Georgian and Victorian houses around Richmond Green), Twickenham (riverside conservation streets and Edwardian terraces), Kew (Victorian houses around Kew Green), Teddington (Edwardian terraces and villas), East Sheen (Edwardian family houses near Sheen Common) and Ham (period cottages and houses by Ham Common) — these are the Richmond upon Thames pockets our drawings cover most. Heritage designations here include Richmond Green, Twickenham Riverside, Kew Green, Ham Common and East Sheen (Sheen Common). Richmond upon Thames Council weighs each proposal against Richmond Local Plan and the House Extensions and External Alterations SPD, where roof alterations and dormers visible from the street or river are strongly resisted. On roofs the borough is pitched roofs on the villas and butterfly roofs on the terraces, over Victorian and Edwardian villas and terraces, Georgian houses near the river and interwar semis in the outer wards.
A wraparound is the ambitious ground-floor move, and Richmond upon Thames has the stock that suits it — the borough is built largely from Victorian and Edwardian villas and terraces, Georgian houses near the river and interwar semis in the outer wards, and the terraces and semis with an L-shaped back addition give you both a side alley to infill and a rear garden to project into. Do both in one L-shaped sweep and the kitchen, dining and living space merge into a single room that runs the full width of the house and out into the garden. Richmond upon Thames Council assesses the scheme against Richmond Local Plan and the House Extensions and External Alterations SPD, and because the footprint is large it looks hardest at what survives of the garden.
The drawings carry the argument. We show the retained private amenity space to scale, prove the rear projection sits within the depth the council accepts for the house type, and set the side leg so it clears the boundary and keeps the neighbour's daylight — a wraparound touches two boundaries, not one, so both neighbour relationships are drawn out. The borough's exceptional conservation coverage means design detail and materials are scrutinised closely, which on a footprint this size is where a scheme is won or lost.
Where Richmond upon Thames's streets sit in conservation areas — Richmond Green, Twickenham Riverside, Kew Green, Ham Common and East Sheen (Sheen Common) among them — a wraparound is never permitted development and the design is read against the area's character. Richmond is one of London's most conservation-heavy boroughs, with widespread Article 4 directions — on many streets even minor external alterations that would be permitted development elsewhere need a full application. We settle the designation before the footprint is fixed.
A wraparound in Richmond upon Thames almost always needs a full householder application, because joining a side infill to a deep rear extension takes it past permitted-development limits. You will need to apply to Richmond upon Thames Council if any of these apply — and for a true wraparound, at least one always will:
We draw the L-shaped footprint against the retained garden, the rear depth within the council's limit for your house type and the two neighbour boundaries the side and rear legs touch — the things Richmond upon Thames Council's officers and both neighbours check — then submit a validation-complete householder application.
Below is Richmond upon Thames Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Richmond grants a fair share of householder applications, but its dense conservation-area and Article 4 coverage makes design quality and roof visibility decisive. A wraparound stands or falls on the garden it leaves and the two boundaries it meets, so a pack that settles both upfront is decided faster and refused less often than a DIY submission.

Across Richmond, Twickenham and Kew, the approved wraparound is a single-storey L that reads as one considered addition rather than two bolted together: the rear leg kept to the depth the council accepts, the side leg matched to the host brick and roofed with a glazed flat or lantern, and enough garden left to satisfy the borough's private-amenity expectation. On the borough's victorian and edwardian villas and terraces, this is the biggest transformation the ground floor can take in a single application.
Roof alterations and dormers visible from the street or river are strongly resisted. We size the footprint so the garden that remains still works, keep the eaves and roof low enough to protect both neighbours' light, and present the whole L as a single scheme — which reads far more clearly to Richmond upon Thames Council than a side return and a rear extension submitted as separate, overlapping proposals.
We draw L-shaped wraparounds on the terraced and semi-detached streets across the borough. A few of the neighbourhoods where Richmond upon Thames wraparounds come up most often:

A wraparound is the two smaller extensions combined — which changes what Richmond upon Thames Council needs and what the ground floor gains. This is how the options compare.
| Ground-floor option | Permitted development? | What it gains | What Richmond upon Thames Council checks |
|---|---|---|---|
| Side return only | Sometimes, within width and height limits | Full-width kitchen | Width, roof glazing |
| Rear extension only | Often, within the depth limit | Deeper living space | Rear depth, neighbour daylight |
| Wraparound (side + rear) | No — full application | Largest open-plan ground floor | Combined footprint, garden retained |
| Two-storey wraparound | No — full application | Room above as well as below | Bulk, overlooking, two boundaries |
In conservation areas such as Richmond Green and Twickenham Riverside, a wraparound is never permitted development and always needs a full application.
A fixed process built around how Richmond upon Thames Council validates and decides wraparound applications — most drawings are submission-ready within seven days of survey.
Send us your Richmond upon Thames postcode and house type. We confirm your conservation and Article 4 status, measure the garden against the borough's amenity expectation, and score your odds against live Richmond upon Thames Council decisions.
We measure the side alley, the rear building line, the garden depth and both neighbours' window heights — the numbers the footprint, rear depth and two-boundary daylight tests depend on.
Chartered designers develop the L-shaped extension to your brief, drawn to Richmond upon Thames Council's extension guidance with the retained garden, rear depth and both boundary junctions detailed on the page.
We submit the householder application, manage validation and case-officer queries, and revise the drawings free until Richmond upon Thames Council issues its decision.
Almost always. A wraparound joins a side-return infill to a rear extension, and that combination takes the footprint past what permitted development allows, so it needs a full householder application to Richmond upon Thames Council. Only the rare, very shallow case stays within the limits. On designated land — a conservation area such as Richmond Green and Twickenham Riverside — a wraparound is never permitted development, so an application is certain.
It is an L-shaped extension that fills the side return and wraps around into a full-width rear extension in one continuous sweep, so the kitchen, dining and living space become a single open room the width of the house. Richmond upon Thames's period terraces and semis with an L-shaped back addition suit it well, which is why the wraparound is the borough's biggest single-storey extension. Richmond upon Thames Council is the decision-maker.
Richmond upon Thames Council expects a usable amount of private garden to survive, because a wraparound is the deepest single-storey footprint and takes the most outdoor space. There is no single fixed figure — it is judged on the plot and the borough's amenity guidance — so we draw the retained garden to scale and size the extension around it, rather than maximising the build and hoping it passes.
Usually on both sides. A wraparound touches two boundaries — the side leg runs along one neighbour and the rear leg can affect the other — so the Party Wall etc. Act often applies to each, and notice must be served before work starts. This is separate from Richmond upon Thames Council's planning decision. We detail both boundary junctions on the drawings and flag the notices early so surveyors can be appointed without delaying the build.
Built as one project it usually is, and it reads better to Richmond upon Thames Council too. A single wraparound application covers the whole L-shaped footprint in one decision rather than two overlapping submissions, and the build shares one set of foundations, one roof and one disruption. We draw it as a single coherent scheme so the council assesses one clear proposal instead of piecing two together.
We price each Richmond upon Thames wraparound individually, because garden depth, side-alley width and roof form vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Richmond upon Thames Council approves, and we confirm the retained-garden and boundary position at the outset. Call 020 7864 7245 to start.
