Tottenham (N17) in Haringey mixes listed Georgian villas along Bruce Grove with streets of Victorian terraces, and the everyday brief here is a rear kitchen extension or a rear-dormer loft to add a bedroom without leaving a well-served neighbourhood.

With the Bruce Grove and Tottenham Green conservation areas both covering parts of N17, we check whether your home sits inside a boundary and, if so, steer materials and roof detailing carefully before deciding between permitted development and a full householder application.

Planning in Tottenham (N17): what to know before you apply

Away from the conservation areas, rear extensions and loft conversions typically proceed under permitted development or a lawful-development certificate. Within Bruce Grove or Tottenham Green, or near the listed High Road villas, a full householder application with sympathetic detailing is expected.

Typical Tottenham housing stock

Listed Georgian villas and Victorian terraces along and behind the historic High Road corridor, with later Victorian and Edwardian streets of two-storey bay-fronted houses making up the residential grain.

House Extension Drawings for Tottenham (N17) homes: the package and the process

Every house extension drawings we prepare for an Tottenham property is drawn to London Borough of Haringey’s validation standards and tuned to the N17 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.

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.

FAQ

House Extension Drawings in Tottenham N17 — FAQs

How far can I extend without planning permission in London?+
Under permitted development, single-storey rear extensions can reach 3m (terraced/semi) or 4m (detached), or up to 6–8m under the prior-approval larger-home scheme — but conservation areas and Article 4 directions can remove these rights. We check your property first.
Do extension drawings include structural calculations?+
Our full package includes structural drawings and calculations coordinated in-house, so your builder can price and build without waiting on an engineer.
How long do extension drawings take?+
Typically about 7 days from survey to a full drawing set delivered to your online portal.
Will my rear extension need a party wall agreement?+
If you build up to or on a shared boundary, excavate near a neighbour's foundations, or cut into a party wall for a steel, the Party Wall etc. Act 1996 usually applies. Our drawings show the works clearly so a party wall surveyor — or your neighbour — can see exactly what is proposed, which keeps that process quick.
Can I extend a house in a conservation area?+
Yes, but conservation areas and Article 4 directions commonly remove permitted development for rear and side extensions, so the work needs a full householder application designed to the council's heritage guidance. We confirm your property's designation before recommending a route.
Do I need planning permission for a loft conversion in Haringey?+
On the Edwardian terraces of the Harringay Ladder and the streets of Crouch End, hip-to-gable and dormer lofts frequently qualify as permitted development within the volume limits, so a full application isn't always needed. Conservation areas — Highgate, Crouch End and Muswell Hill in particular — restrict this. We check your street first and can confirm permitted development with a Lawful Development Certificate.
Will protected views toward Alexandra Palace affect my project?+
They can for roof-level proposals. Haringey protects views toward Alexandra Palace and across the borough's hills, so a dormer or roof extension on a prominent site may be assessed against that setting. We check whether your address falls within a protected view and design the roof form to respect it, which keeps the application on track.
What does Haringey expect on the Harringay Ladder?+
The Ladder has a consistent Edwardian terrace character the council expects extensions and lofts to respect — matching the building line, roofline and materials of the street. We design to that established pattern rather than imposing a standard template, which is what carries applications to consent on these streets.
How long does Haringey Council take to decide?+
Haringey determines most householder applications within the statutory eight-week period once validated; Highgate, Crouch End and Muswell Hill conservation cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Haringey?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Haringey approves. A Harringay Ladder loft and a Highgate conservation application differ in the evidence required, so we quote once we understand your street and project rather than by the hour.
