Planning and building regulation drawings in South Tottenham (N15)

South Tottenham grew up as a grid of late-Victorian terraces, and that's still the backbone of the district today. Walk the residential streets between West Green Road and Seven Sisters Road and you're mostly looking at bay-fronted terraced houses built for a single family and long since split, extended, or both. Along West Green Road itself, and on the Seven Sisters and Page Green frontages of Broad Lane and Wakefield Road, the ground floors turn commercial: shops with flats stacked above them, a pattern that shapes how those buildings can be altered.

That mix means the questions homeowners bring us vary block by block. On a quiet terrace off Summerhill Road, the common ask is a rear extension or a loft conversion to add a bedroom without losing the garden. On the busier frontages, it's more often about converting upper floors into self-contained flats, which counts as a change of use and needs planning permission regardless of the building's history. Owners near the Clyde Circus conservation area sometimes assume protected status kills any project outright; it doesn't, but it does mean the council looks closely at anything visible from the street, from render to roofline.

What ties the district together is uncertainty over permitted development rather than a single blanket rule. Haringey hasn't published its householder Article 4 schedule for South Tottenham to the national register, so we can't tell you from open data alone whether a given house has already lost its permitted development rights. We check the live schedule with the council for your specific address before we draw anything, rather than guessing from a postcode.

Planning in South Tottenham: what to know before you apply

Haringey handles householder applications in South Tottenham the way it does across the borough: a validation check on drawings and forms, then assessment against its local plan policies for extensions, lofts, and conversions. Where a property sits within the South Tottenham conservation area, the assessment adds a design review of anything visible from the street, since the council is protecting the historic grain of the area rather than individual buildings. The same applies along the Seven Sisters and Page Green conservation area, where Broad Lane, Wakefield Road, and the High Road's east side form part of the wider Tottenham High Road historic corridor. Because Haringey hasn't confirmed which South Tottenham addresses carry a household Article 4 direction, we treat permitted development as unconfirmed until the council tells us otherwise for that specific property. That's a slower first step than in boroughs with a published register, but it avoids submitting or building work that turns out to need permission after all. Once we know the position for your address, we draw to whichever route, permitted development or full application, actually applies.

Applications are decided by London Borough of Haringey its planning pages.

  • A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
  • An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
  • One or more constraints are unknown — we check the council's registers as part of the free appraisal.
  • Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

This is a first-pass indication from the national rules, not planning advice for your property. Your council's registers, any Article 4 schedule and the exact dimensions decide it — the free appraisal checks all three before we recommend a route.

FAQ

South Tottenham (N15) — FAQs

Does living in a conservation area mean I can't extend my house?+
No. A conservation area controls how a change looks, not whether you can make one. In South Tottenham that usually means the council pays closer attention to materials, roofline, and anything facing the street, while a rear extension that isn't visible from public view often faces far less scrutiny. It's a design conversation, not a ban.
My house has a shop underneath with a flat above, does that change what I can do?+
Yes, in one specific way: turning that upper floor into a separate self-contained flat is a change of use and needs planning permission, whatever the building's age or condition. Internal alterations that leave the exterior unchanged need no planning application.
