House Extension Drawings in Kentish Town NW5
Fixed-fee, MCIAT-chartered house extension drawings for Kentish Town (NW5) homeowners — London Borough of Camden validation and local constraints handled from the start.
Kentish Town (NW5) is predominantly Victorian, with two conservation areas — Dartmouth Park on the rising ground to the north and Inkerman in the streets off Kentish Town Road — and Camden's Article 4 layer over the top. It is a district where the difference between one street and the next genuinely changes the route to consent.
Camden's Basements direction removes permitted development rights for basement works throughout, so lower-ground schemes need a full application. The Class E to C3 direction, in its outside-the-CAZ form, removes the permitted commercial-to-residential change here — which matters along Kentish Town Road and Fortess Road, where the shop-to-flat conversion is a common project and now needs planning rather than prior approval. In the Dartmouth Park and Inkerman conservation areas, frontages and rooflines are controlled, and the rise toward Dartmouth Park Hill means rear extension levels and overlooking are assessed against the slope. We check the boundaries and the Article 4 position for an NW5 address before drawing to Camden's guidance.
Planning in Kentish Town (NW5): what to know before you apply
NW5 falls under Camden's Basements Article 4 direction, removing permitted development rights for basement works, and the outside-CAZ Class E to C3 direction, which removes the permitted commercial-to-residential change — so shop-to-flat conversions along Kentish Town Road and Fortess Road need full planning applications rather than prior approval. The Dartmouth Park and Inkerman conservation areas control frontages and rooflines, and the rising ground toward Dartmouth Park Hill brings level and overlooking assessments into rear extension design.
Typical Kentish Town housing stock
Victorian terraces through the centre and along Fortess Road, larger Victorian semi-detached and terraced houses climbing Dartmouth Park Hill, and a substantial share of the stock converted to flats.

House Extension Drawings for Kentish Town (NW5) homes: the package and the process
Extension drawings are read for their dimensions. The proposed plan needs depth measured from the original rear wall — not from a previous extension — eaves and ridge heights taken from existing ground level, and the distance to each boundary marked. A site plan showing how much garden remains is what an officer reaches for when the amenity question comes up.
We draw the existing building accurately first, because everything else is measured from it. Where the original footprint has already been added to, that history goes on the drawing: it decides which allowances are still available and it is the first thing an officer checks against the council's own records.
The plot decides the extension type long before taste does. A mid-terrace has depth to work with and an alley if it is lucky; a semi has one clear flank; a detached house can go wide. Reading the building form first is what stops a design being drawn that the plot cannot take.
Which extension types do you draw?
Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.
Rear extension
A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.
Side-return
Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.
Wraparound
Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.
Double-storey
Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.
Basement
Creates space downward where footprint is limited, with structural and party-wall care.
Do I need planning permission for a house extension in London?
Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing. The current depth, height and eaves limits are set out in full in the guide to planning permission for a rear extension, and where you would rather one practice ran the design, the application and the building-regulations stage together, Architectural Drawings covers that full scope.
How do you maximise the footprint the council will approve?
We know each borough's depth, height and daylight standards, so we design to the edge of what will be approved rather than guessing — and we check the 45-degree neighbour daylight rule and any rear building line before submission. Where a plot is tight we test a permitted-development scheme against a slightly larger householder application and show you the trade-off in space, cost and timescale, so the drawn scheme is the one that actually maximises value rather than just floor area.
