Planning and building regulation drawings in Greenwich (SE10)

Walk from the market up toward Crooms Hill and the housing stock tells its own story: Georgian terraces giving way to Victorian streets. Royal Hill and Crooms Hill still carry the proportions their builders drew two centuries ago, and Ashburnham Grove and Gloucester Circus sit among the streets the council expects any alteration to respect.

That's the part people underestimate when they first ask us about a loft or a side-return kitchen here. Greenwich isn't one planning environment, it's several layered on top of each other. A homeowner on Gloucester Circus and one further out toward East Greenwich can face genuinely different processes for what looks like the same job, because the streets sit inside different conservation boundaries with different sensitivities. We start every drawing with that check, because getting it wrong costs a redesign, not just a resubmission.

Greenwich Park itself shapes plenty of what's buildable nearby too. Proposals near its edges get read against the openness and views the park protects, not just the usual daylight and amenity tests. None of that makes extending here unusual, most owners still get their rear extension or loft conversion through. It just means the drawings have to earn their approval on the specifics of the street, not a generic template.

Planning in Greenwich: what to know before you apply

Greenwich's planning team pays close attention to anything touching the borough's protected townscape, and West Greenwich and East Greenwich sit inside that scrutiny alongside Blackheath. Alterations that would be routine elsewhere, new windows, re-roofing, a replacement door, often need permission here because Article 4 directions strip out the usual permitted development allowance across those conservation areas. The Ashburnham Triangle carries the same restriction. Practically, that means side extensions and roof changes get assessed on materials, proportions and how they read from the street, not waved through on size alone. The council also checks proposals against the setting of the wider Maritime Greenwich World Heritage designation where relevant, so long views and the historic streetscape carry real weight in the decision. We map which of these controls apply to a specific address before we draw anything, because the answer changes the whole approach to a loft, a rear extension or even a new door.

Applications are decided by Royal Borough of Greenwich 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.

FAQ

Greenwich (SE10) — FAQs

Do I need planning permission for a loft conversion in Greenwich?+
Often yes, and more often than in a borough without Article 4 controls. If your street sits inside West Greenwich, East Greenwich or the Ashburnham Triangle, the Article 4 direction removes the usual permitted development rights for external changes, which can include dormer windows and roof alterations that would otherwise be automatic elsewhere. We check the conservation area boundary against your address first, since it decides whether you're submitting a full application or working within existing rights.
Why does my house need a heritage assessment for a rear extension?+
Because Greenwich sits within the Maritime Greenwich World Heritage Site and its buffer, and the council reads extension proposals near that boundary against the long views and townscape it protects. It doesn't mean rear extensions get refused, most don't, but the drawings need to show how the addition sits against the historic streetscape rather than just meeting standard depth and height rules. That's a different conversation to have before you draw than after a refusal.
