Planning and building regulation drawings in Charlton (SE7)

Charlton still has a village at its centre, and that shapes almost every planning conversation homeowners have here. Walk along The Village or up Charlton Church Lane and you're looking at Georgian and early-Victorian cottages clustered around Charlton House and St Luke's church, a pocket that reads more like a Kent market town than southeast London. Step away from that core and the housing changes fast: Victorian and Edwardian terraces climb the surrounding slopes, and interwar semis fill many of the roads further out. A loft conversion that sails through on a 1930s semi can mean a completely different set of questions on a cottage two streets over.

That split is the thing to understand before you sketch anything. Homes inside Charlton Village Conservation Area face tighter scrutiny on materials, windows and anything visible from the front, because the council is protecting the setting around a Grade I listed building and the streets that lead into it. Move a few hundred metres out, onto Charlton Road and the surrounding terraces, and you're usually working with standard householder rules rather than conservation-area constraints. Sloping plots are common around Charlton Park too, and they change how a rear or side extension gets designed long before anyone talks about planning permission.

None of this rules work out. It means the drawings have to answer for the address, not for a generic idea of "Charlton." We check whether a property sits inside the conservation area, whether it's close enough to Charlton House to matter, and whether the site slopes in a way that affects roof lines or floor levels, before we draw a single wall.

Planning in Charlton: what to know before you apply

Royal Greenwich assesses householder applications against what's actually on the ground at that address, and in Charlton that usually comes down to two things: proximity to the historic village core and the slope of the plot. Inside Charlton Village Conservation Area, alterations near Charlton House and St Luke's church get closer attention on materials and front-elevation changes, and permitted development rights can be narrower than homeowners expect. The conservation area itself doesn't carry a blanket Article 4 direction, but a separate direction applies around Rectory Field nearby, so it's worth confirming your specific street with the council rather than assuming what applies to a neighbour applies to you. Outside the village core, on the Victorian terraces and interwar semis further out, applications tend to follow the borough's ordinary householder process, though sloping sites still shape what a rear extension or loft dormer can achieve. We check the conservation-area boundary and any Article 4 position for your address before drawing, so the application isn't built on an assumption.

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

Charlton (SE7) — FAQs

Does living near Charlton House mean I can't extend?+
Not automatically. It means the council looks harder at anything visible from the village core, particularly materials and front-facing changes, because Charlton House is Grade I listed and its setting is protected. A rear extension that isn't visible from the street or the church often has more flexibility than a change to the front elevation. We assess the specific relationship between your property and the village before proposing a design.
My house is on Canberra Road, not in the village. Does the conservation area still apply to me?+
Charlton Village Conservation Area is centred on the historic core around The Village and Charlton Church Lane, and it doesn't cover the whole of SE7. Boundaries don't always follow what feels intuitive, though, and a nearby Article 4 direction around Rectory Field means it's worth checking your exact address with Royal Greenwich rather than assuming standard permitted development rights apply.
