Eltham (SE9) sits in the Royal Borough of Greenwich and is best known for the Progress Estate at Well Hall — a 1915 Arts-and-Crafts garden suburb that inspired much interwar housing and has been a conservation area since 1971. An Article 4 direction covers the estate, so on those streets even small external changes need consent, and rear and loft projects have to be handled with real care for the original detailing.

Away from the estate, much of Eltham is consistent interwar semi-detached and terraced housing where side-return, rear and loft projects are the staple. The district also carries the setting of Eltham Palace and its listed gardens. We check where an Eltham property sits relative to the Progress Estate Article 4 area and the palace setting before recommending a permitted-development or full-application route under Greenwich's guidance.

Planning in Eltham (SE9): what to know before you apply

Eltham's Progress Estate at Well Hall carries a conservation-area designation and an Article 4 direction (1973), so permitted-development rights are removed across the estate and external changes need planning permission. Elsewhere in SE9 many interwar houses retain PD rights for rear and loft work, but the consistent frontages and the setting of Grade I listed Eltham Palace mean elevation and roof changes are assessed closely. We confirm which controls apply to a specific address before drawing.

Building Regulations Drawings for Eltham (SE9) homes: the package and the process

A Full Plans submission is a technical argument, not a picture. The sheets carry construction build-ups for floors, walls and roof, insulation values and junction details, drainage runs and invert levels, fire escape routes and protected stairs, ventilation provision and the structural elements that carry it all. Building Control checks each against the Approved Documents before work starts.

We coordinate the structural design with the architectural sheets in-house, so the beam sizes on the calculations are the beam sizes on the sections, and the openings your builder prices are the openings that were approved. Where a detail is unusual, we draw it rather than leave it to be resolved on site.

Construction details follow the existing fabric. Solid brick walls, suspended timber floors and uninsulated roofs each need a different build-up to reach the required performance, and a terrace has party wall junctions to detail that a detached house simply does not.

What do building regulations drawings cover?

A building control package translates the approved design into a buildable, compliant specification.

  • Construction sections and detailed junctions
  • Structural drawings and calculations (steel beams, foundations, loadings)
  • Part L thermal performance and insulation specification
  • Fire safety — escape routes, protected structure, alarms
  • Drainage and ventilation layouts

Full Plans or Building Notice — which should I choose?

A Full Plans application has your drawings checked and approved by Building Control before work starts, giving certainty and a document lenders and buyers like to see. A Building Notice lets simpler work start sooner but is inspected as it proceeds, with less up-front certainty. For most London extensions and loft conversions we recommend Full Plans, and prepare the package accordingly. Building regulations are a separate consent from planning permission, and the two are often confused — the explainer on permitted development rights sets out which projects escape a planning application but still need building-regs approval, and Architectural Drawings covers the same building-regs package where you want a chartered practice to carry it through to sign-off.

Why coordinate structural calculations in-house?

When the same team draws the building and calculates its structure, the steel schedule matches the drawings and the builder never waits on a missing detail. It removes the classic gap between an architect's drawings and a separately-appointed engineer's calculations.

FAQ

Building Regulations Drawings in Eltham SE9 — FAQs

Do I need building regulations approval as well as planning permission?+
Almost always, yes. Planning permission covers what the building looks like; building regulations cover how safely it is built. Most extensions and loft conversions need both.
How long does Building Control approval take?+
A Full Plans application is typically assessed within about five weeks. We prepare a complete package and respond to any conditions promptly, so approval is not held up by missing detail.
Can building regulations drawings be done after planning approval?+
Yes. Many homeowners secure planning permission first, then commission the building regulations package before starting on site. We can pick a project up at either stage.
Are structural calculations included?+
Yes — we produce structural drawings and calculations in-house as part of the building regulations package, so your builder has everything to price and build.
Can you submit to Building Control for me?+
Yes, we prepare and submit the Full Plans package and respond to any Building Control queries.
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.
