L-shaped wraparound drawings for Wandsworth — a full-width rear extension married to the side-return infill so the whole ground floor opens up, drawn to Wandsworth Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Wandsworth Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Wandsworth carries at least one Article 4 direction, and conservation areas including Wandsworth Common, Nightingale Triangle and Tonsleys remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wandsworth is determined against an 8-week statutory target.
Battersea (Victorian terraces and mansion flats near the park), Balham (Edwardian terraces around the Nightingale Triangle), Tooting (long Victorian terraces off the high road), Putney (Edwardian villas and riverside streets), Earlsfield (compact Victorian terraces between the commons) and Southfields (the Magdalen Park grid of Edwardian houses) — these are the Wandsworth pockets our drawings cover most. Heritage designations here include Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park. Wandsworth Council weighs each proposal against Wandsworth Local Plan and the borough's Housing and Basements SPDs, where the borough applies detailed basement-development policies on top of the usual tests. Much of Battersea and Balham is converted flats and maisonettes, which carry no householder permitted-development rights.. On roofs the borough is butterfly / valley roofs on the terraces and pitched roofs on the villas, over Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas.
A wraparound is the ambitious ground-floor move, and Wandsworth has the stock that suits it — the borough is built largely from Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas, 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. Wandsworth Council assesses the scheme against Wandsworth Local Plan and the borough's Housing and Basements SPDs, 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. Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, which on a footprint this size is where a scheme is won or lost.
Where Wandsworth's streets sit in conservation areas — Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park among them — a wraparound is never permitted development and the design is read against the area's character. Several Wandsworth conservation areas carry Article 4 directions, and the borough's dense conservation coverage means many terraced streets need a full application for works that would be PD elsewhere. We settle the designation before the footprint is fixed.
A wraparound in Wandsworth 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 Wandsworth 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 Wandsworth Council's officers and both neighbours check — then submit a validation-complete householder application.
Below is Wandsworth Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wandsworth grants a healthy share of householder applications, but its uniform Victorian terraces mean side returns and roof alterations are assessed in centimetres against the neighbours. 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 Battersea, Balham and Tooting, 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 terraces, this is the biggest transformation the ground floor can take in a single application.
The borough applies detailed basement-development policies on top of the usual tests. 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 Wandsworth 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 Wandsworth wraparounds come up most often:

A wraparound is the two smaller extensions combined — which changes what Wandsworth Council needs and what the ground floor gains. This is how the options compare.
| Ground-floor option | Permitted development? | What it gains | What Wandsworth 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 Wandsworth Common and Nightingale Triangle, a wraparound is never permitted development and always needs a full application.
A fixed process built around how Wandsworth Council validates and decides wraparound applications — most drawings are submission-ready within seven days of survey.
Send us your Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth Council. Only the rare, very shallow case stays within the limits. On designated land — a conservation area such as Wandsworth Common and Nightingale Triangle — 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. Wandsworth'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. Wandsworth Council is the decision-maker.
Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth Council approves, and we confirm the retained-garden and boundary position at the outset. Call 020 7864 7245 to start.
