L-shaped wraparound drawings for Haringey — a full-width rear extension married to the side-return infill so the whole ground floor opens up, drawn to Haringey Council's guidance, delivered in days and revised free until your decision, with a free approval-odds check first.
Haringey 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-return and rear extensions are weighed against the tight party-wall relationships of the Ladder terraces, 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.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Haringey carries at least one Article 4 direction, and conservation areas including Highgate, Crouch End and Muswell Hill remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Haringey is determined against an 8-week statutory target.
Highgate (historic village streets shared with Camden and tightly controlled), Crouch End (Victorian and Edwardian terraces around the Broadway), Muswell Hill (Edwardian houses with pronounced gables), Harringay (the Victorian Ladder of parallel terraced streets), Tottenham (Victorian terraces and the Tottenham Green conservation area) and Wood Green (mixed Victorian terraces and converted flats) — these are the Haringey pockets our drawings cover most. Heritage designations here include Highgate, Crouch End, Muswell Hill, Tottenham Green and Noel Park. Haringey Council weighs each proposal against Haringey Local Plan and the borough's Alterations and Extensions SPD, where the borough's HMO Article 4 now pulls many conversions into the full planning system. Converted flats are common across Harringay, Wood Green and Tottenham, and flats hold no householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs on the Victorian terraces and gabled and hipped roofs on the Edwardian houses, over Victorian and Edwardian terraces, large Edwardian houses in Muswell Hill and converted period flats.
A wraparound is the ambitious ground-floor move, and Haringey has the stock that suits it — the borough is built largely from Victorian and Edwardian terraces, large Edwardian houses in Muswell Hill and converted period flats, 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. Haringey Council assesses the scheme against Haringey Local Plan and the borough's Alterations and Extensions 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. Side-return and rear extensions are weighed against the tight party-wall relationships of the Ladder terraces, which on a footprint this size is where a scheme is won or lost.
Where Haringey's streets sit in conservation areas — Highgate, Crouch End, Muswell Hill, Tottenham Green and Noel Park among them — a wraparound is never permitted development and the design is read against the area's character. Haringey applies Article 4 directions in areas such as Noel Park and runs a borough-wide direction that removes permitted-development rights for small houses in multiple occupation. We settle the designation before the footprint is fixed.
A wraparound in Haringey 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 Haringey 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 Haringey Council's officers and both neighbours check — then submit a validation-complete householder application.
Below is Haringey Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Haringey approves a clear majority of householder applications, with terrace party-wall relationships and the HMO Article 4 the most frequent sticking points. 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 Highgate, Crouch End and Muswell Hill, 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 terraces, this is the biggest transformation the ground floor can take in a single application.
The borough's HMO Article 4 now pulls many conversions into the full planning system. 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 Haringey 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 Haringey wraparounds come up most often:

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