Building Regulations Drawings · SE3 Blackheath
Greenwich controls the Blackheath and Cator Estate conservation areas; the post-war Span estates also carry conservation protection.
If your property sits elsewhere in the borough, the borough-wide page for building regulations drawings in Greenwich covers the same service across every ward.
Building regulations drawings for a Blackheath project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Greenwich Council Building Control or an approved inspector. On SE3's georgian and victorian houses around blackheath, large, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Blackheath, Blackheath Village, Kidbrooke, Westcombe Park fringe.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across Blackheath, Blackheath Village, Kidbrooke, Westcombe Park fringe in SE3, the dominant property is georgian and victorian houses around blackheath, large detached and semi-detached villas, and the modernist span estates of kidbrooke. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Greenwich Council judges each on design quality and neighbour impact. We survey the specific Blackheath property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE3 streetscape.
Housing stock in SE3: Georgian and Victorian houses around Blackheath, large detached and semi-detached villas, and the modernist Span estates of Kidbrooke.
Within the district: Blackheath, Blackheath Village, Kidbrooke, Westcombe Park fringe.
Streets we know in SE3: the Cator Estate roads, Blackheath Park, Montpelier Row and the Span estates off Foxes Dale. Each road has its own building line, boundary treatment and precedent that Greenwich Council weighs when assessing a building regulations drawings scheme.
Conservation areas: Blackheath Park (Cator Estate), Blackheath Village, Westcombe Park. Inside these, most external work needs full planning and a Heritage Statement.
Getting around SE3: Blackheath and Kidbrooke rail to London Bridge, Cannon Street and Victoria.
Regeneration: Blackheath falls within or beside the Kidbrooke Village (one of London's largest estate regenerations), which shapes local planning policy and design expectations.
Property values: around £450,000 for a flat and £900,000-£1.6m for a house — a useful gauge of the build value an extension or loft adds in SE3.
Borough character: World Heritage Site status in Greenwich town centre adds heritage weight; outer borough areas (Eltham, Thamesmead) generally permissive.
Plans, sections and elevations at 1:50 with full annotation and material specification.
U-values for walls, roof, floor and glazing; SAP or SBEM where required; compliance statement.
Chartered engineer sign-off on beams, pad foundations, lintels, roof structure.
Escape routes, compartmentation, smoke alarms, fire-rated construction detail.
Soil and vent pipe routes, MVHR coordination, EV charging (Part S).
Full Plans submission to Greenwich Council Building Control or an approved inspector with inspections coordinated through to completion certificate.
Single planning or building-regs submission.
Planning + building regs + structural.
Listed, conservation or complex sites.
Strongly. The Blackheath, Blackheath Park (Cator Estate) and Westcombe Park conservation areas mean full planning with a Heritage Statement for external changes, and Greenwich scrutinises materials, boundaries and roofscape closely. We design to that standard for the Georgian and Victorian houses around the heath.
It needs care. The modernist Span estates off Foxes Dale are conservation areas with strong design controls and residents' covenants protecting their original character, so even windows and finishes are controlled. We design sympathetically to the Span aesthetic and handle both the planning and any management-company consent.
Kidbrooke Village is one of London's largest estate regenerations — thousands of new homes, a new station forecourt and parkland — lifting values across SE3. For an individual house project the binding controls remain Permitted Development limits and the local conservation designation, which we check for your address.
Outside the conservation areas, usually yes — a rear dormer or hip-to-gable within the volume allowance, confirmed by a Lawful Development Certificate. Inside the Blackheath or Cator Estate designations, roof changes need full planning and are assessed on their impact on the historic roofscape. We confirm which applies to your road.
With Blackheath property at around £450,000 for a flat and £900,000-£1.6m for a house, the professional drawing fee is a small fraction of the value the work adds to SE3's georgian and victorian houses around blackheath, large. Greenwich Council charges its own statutory application fee on top (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every SE3 address.
For a SE3 project across Blackheath, Blackheath Village, Kidbrooke, Westcombe Park fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Greenwich Council (8 weeks for a householder application). We carry the Blackheath application through every officer query to the decision.
Blackheath (SE3) sits primarily in Greenwich, so applications are decided by Greenwich Council. Conservation areas within SE3 include Blackheath Park (Cator Estate), Blackheath Village, Westcombe Park, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind building regulations drawings in Blackheath — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Greenwich Council Building Control or an approved inspector. On SE3's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on SE3 homes.

Every SE3 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. SE3 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| SE3 | Blackheath / Kidbrooke | Georgian villas, Victorian terraces | A building regulations package in Blackheath / Kidbrooke may land with Greenwich Council or Lewisham Council — SE3 crosses the boundary, and the SE3 policies map decides it street by street. |
| SE3 | Blackheath (Greenwich) | Georgian villas, Victorian terraces | A SE3 address in Blackheath (Greenwich) can route building control through Greenwich Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |
| SE3 | Kidbrooke | New-build, post-war fragments | Kidbrooke sits inside SE3. The Building Regulations check can be bought from Greenwich Council building control or from a private approved inspector — the owner chooses, and the choice is not tied to the borough boundary. |
| SE3 | Blackheath | Georgian villas, Victorian terraces | Blackheath is inside SE3. Building control is not a council monopoly: an approved inspector can take the same job, discharging the same duty under the Building Regulations, wherever the address sits. |
| SE2 | Abbey Wood | mixed stock | Adjoining district to SE3. Building control here can go to Greenwich or to an approved inspector, on the same terms as in SE3. |
| SE7 | Charlton | Victorian villas, 1930s semi-detached | Adjoining district to SE3. Building control here can go to Greenwich or to an approved inspector, on the same terms as in SE3. |

| SE4 | Brockley | Victorian and Edwardian terraces | Adjoining district to SE3. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Lewisham. |
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | Adjoining district to SE3. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Lewisham. |

Roof pitch, wall build-up and plot depth change every few SE3 streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a SE3 (Blackheath / Kidbrooke) building regulations package: Greenwich Council maintains 20 conservation areas, including Eltham Park, Greenwich Town Centre (World Heritage Site), Blackheath. Inside any of them a SE3 (Blackheath / Kidbrooke) building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Charlton sets the tone for SE3 (Blackheath / Kidbrooke) casework.
No blanket Article 4 over SE3 (Blackheath / Kidbrooke): Greenwich Council has not withdrawn permitted development across SE3 (Blackheath / Kidbrooke), so a building regulations package outside a SE3 (Blackheath / Kidbrooke) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a SE3 owner wants on file.
The building fabric around SE3 (Blackheath / Kidbrooke): Georgian in Greenwich town centre; Victorian terraces in East Greenwich, Charlton; inter-war semi-detached in Eltham; new-build along the riverside. World Heritage Site status in Greenwich town centre adds heritage weight; outer borough areas (Eltham, Thamesmead) generally permissive. A building regulations package in SE3 (Blackheath / Kidbrooke) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Greenwich Council.
