Greenwich (SE10) is among the most heritage-sensitive places to build in London: most of its period housing sits within one of the Royal Borough's conservation areas — West Greenwich, Greenwich Park, East Greenwich or the Ashburnham Triangle — and three of those carry Article 4 directions that pull nearly all external work into the planning system. Side-return and rear extensions on the Victorian and Georgian terraces are the staple, but they are judged carefully on materials, proportion and detail.

SE10 also sits within, or beside, the Maritime Greenwich World Heritage Site: the inscribed core is the Old Royal Naval College, Queen's House, Royal Observatory and Cutty Sark, with the surrounding streets in the buffer zone. That means townscape and setting weigh heavily on how schemes are assessed. We check exactly which conservation area — and which Article 4 direction — applies to a Greenwich address before advising on a permitted-development or full-application route.

Planning in Greenwich (SE10): what to know before you apply

Most SE10 houses fall inside the West Greenwich, Greenwich Park, East Greenwich or Ashburnham Triangle conservation areas, and the first three carry Article 4 directions removing permitted-development rights for re-roofing, windows, doors and other external changes. The Maritime Greenwich World Heritage Site and its buffer zone add further townscape scrutiny. We confirm the conservation area and Article 4 status for a specific property before recommending a route and drawing to the Royal Borough's guidance.

Architectural Drawings for Greenwich (SE10) homes: the package and the process

The full architectural package has to serve three audiences that want different things from the same building. Planning officers want context, massing and materials; Building Control wants construction, insulation and fire strategy; your builder wants dimensions precise enough to price and set out from. One coordinated model behind all three keeps them agreeing with each other.

That coordination is the part clients notice later. When the planning set and the construction set are drawn from separate sources, the discrepancies surface on site — a beam that will not fit the approved roof line, a window head that has moved. We issue numbered, revision-controlled sheets so everyone is building from the same version.

Building form also sets how much design work there is to do. A detached house can usually take an addition on its own terms, while a terrace has to negotiate two party walls, a shared roof line and a neighbour's windows — the same brief, several times the coordination.

What do architectural drawings include?

A complete architectural package carries your project from idea to buildable detail, so builders quote accurately and councils and Building Control approve confidently.

  • Concept and feasibility sketches
  • Planning drawings for the local authority
  • Building regulations drawings with construction detail
  • Structural drawings and calculations
  • Schedules, specifications and material annotations

Architect or architectural technologist — which do I need in London?

For residential planning and building regulations work, an MCIAT-chartered technologist produces the same council-accepted drawings with the same professional accountability as an architect, typically at a lower fee. Councils do not score applications by the author's job title — they score the drawings. The table below compares the two on the factors homeowners actually care about.

What are the stages of an architectural drawing package?

A full architectural package moves through clear stages, each producing drawings you own and can act on. You can stop at any stage — many homeowners take a project to planning approval first, then commission the technical package once they are ready to build.

Concept and feasibility

Sketch options that test what your budget, plot and borough will allow, so you commit to a direction before detailed drawing begins.

Planning drawings

The scaled existing and proposed set your council assesses — floor plans, elevations, sections and site plans formatted to the borough's validation checklist.

Building regulations drawings

The construction-level package: sections, junction details, structural calculations and thermal and fire specification for Building Control.

Construction detail

The final layer of detail and schedules your builder prices and works from on site.

FAQ

Architectural Drawings in Greenwich SE10 — FAQs

Are architectural drawings the same as planning drawings?+
Planning drawings are a subset of the architectural package — the drawings used specifically for a planning application. The architectural drawings also include building regulations and construction detail.
Will a technologist's drawings be accepted by my council?+
Yes. MCIAT-chartered technologists are a recognised professional body and their drawings are routinely accepted and approved by every London borough.
Can you take my project all the way to construction?+
Yes — from feasibility through planning, building regulations and structural detail, to a set your builder can price and build from.
Do I own the architectural drawings you produce?+
Yes. The drawings are yours to use, and any competent builder can price and build from them — you are never locked into a single contractor by the drawing package.
Can I commission just the planning stage for now?+
Yes. Many homeowners take a project to planning approval first and add the building regulations and construction package later. We stage the fee to match, so you only pay for the stage you need.
Do I need planning permission for an extension in Greenwich?+
It depends on the area. The interwar and post-war suburbs toward Eltham and Kidbrooke often retain permitted development rights for rear extensions and lofts, while the historic core around West Greenwich and Blackheath sits within conservation areas where those rights are removed. We check your address against the designations first and can confirm permitted development with a Lawful Development Certificate.
How does the Maritime Greenwich World Heritage Site affect my project?+
Proposals within the World Heritage Site or its buffer zone are assessed against the setting of Maritime Greenwich, where the council protects townscape and long views toward the Royal Observatory. It doesn't rule out an extension, but roof-level and prominent works near the site need careful, context-led design. We confirm whether the setting applies to your address before drawing.
Can I extend a home in Blackheath or Westcombe Park?+
Yes, but these conservation areas carry strong design control over materials, rooflines and front elevations, and sloping sites around Blackheath and the Greenwich hills shape what works. We design context-led drawings that respond to the area's Georgian and Edwardian character and the topography, which is what carries applications to consent here.
How long does the Royal Borough of Greenwich take to decide?+
Greenwich determines most householder applications within the statutory eight-week period once validated; World Heritage Site, conservation and protected-view 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 Greenwich?+
We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Greenwich approves. A suburban Eltham extension and a West Greenwich heritage application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
