Greenwich controls the Blackheath and Cator Estate conservation areas; the post-war Span estates also carry conservation protection.


The borough-level guide to party wall services in Greenwich sets out how the same work is handled across the rest of the authority.
Party Wall services in Blackheath cover the notices and awards required when you build near or on a shared wall — almost universal on SE3's terraced and semi-detached houses. Before steel beams, loft conversions or basement work, adjoining owners across Blackheath, Blackheath Village, Kidbrooke, Westcombe Park fringe must be served the correct notices; we prepare them with a schedule of condition.
End-to-end Party Wall Act 1996 service for Blackheath — Section 1, 3 and 6 notices, schedule of condition surveys, party wall award coordination. We handle the process so your Blackheath build starts without neighbour disputes.
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 party wall services 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 party wall services 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.
We review your Blackheath project and confirm which Party Wall Act sections apply — Section 1 (new wall on boundary), Section 3 (adjacent excavation) or Section 6 (line of junction).
Legally-compliant notices prepared and served on all adjoining owners, with 14-day or 1-month response periods tracked.
Photographic and written record of neighbouring properties before work starts — protects you and your Blackheath neighbours from disputes.
Technical drawings showing the proposed works in relation to the party wall, foundations and adjoining structures — required by the Act.
If neighbours dissent, we coordinate the appointment of agreed surveyors or independent surveyors to prepare the Party Wall Award.
Liaison through the award process — method statements, temporary works, access arrangements — until the award is agreed and you can start on site.
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 party wall services 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.
Extensions on a boundary plot can involve two authorities. Everything we draw and submit is listed for SE9 and SE10.

Every SE3 postcode district we draw in, the stock that dominates it and the authority that validates a party wall package there. SE3 fees below are the statutory England rates for 2026, not party wall package estimates.
| Postcode | Area | Dominant stock | What it means for a party wall package |
|---|---|---|---|
| SE3 | Blackheath / Kidbrooke | Georgian villas, Victorian terraces | SE3 straddles a boundary: Blackheath / Kidbrooke addresses fall to Greenwich Council or Lewisham Council, so confirm which authority validates the party wall package before submitting SE3 drawings. |
| SE3 | Blackheath (Greenwich) | Georgian villas, Victorian terraces | Blackheath (Greenwich) sits inside SE3. A party wall matter here is not a council decision: notice is served on the adjoining owner under the Party Wall etc. Act 1996, and a dissent is settled by the appointed surveyors. |
| SE3 | Kidbrooke | New-build, post-war fragments | A SE3 address in Kidbrooke needs notice served under the Party Wall etc. Act 1996 before work to a shared wall or excavation near one. That runs alongside any planning route, and neither waits for the other. |
| SE3 | Blackheath | Georgian villas, Victorian terraces | Blackheath is inside SE3. Lewisham Council determines nothing in a party wall matter — the Act puts it between the two owners, and the surveyors' award is what binds. |
| SE2 | Abbey Wood | mixed stock | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE7 | Charlton | Victorian villas, 1930s semi-detached | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE9 | Eltham / Mottingham | 1930s semi-detached, post-war flats | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE4 | Brockley | Victorian and Edwardian terraces | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE8 | Deptford | Georgian terraces, post-war estates, new-build | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
| SE12 | Lee / Grove Park | mixed stock | Adjoining district to SE3. Party wall notices here run on the same Act and the same timetable — the borough boundary makes no difference to them. |
Roof pitch, wall build-up and plot depth change every few SE3 streets, and each one changes what a party wall package can achieve at that address.
How designation changes a SE3 (Blackheath / Kidbrooke) party wall package: Greenwich Council maintains 20 conservation areas, including Charlton, Eltham Park, Greenwich Town Centre (World Heritage Site). Inside any of them a SE3 (Blackheath / Kidbrooke) party wall 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. Eltham Park sets the tone for SE3 (Blackheath / Kidbrooke) casework.
SE3 (Blackheath / Kidbrooke) permitted development status: there is no borough-wide direction from Greenwich Council, so a party wall package at a SE3 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SE3 (Blackheath / Kidbrooke) sale to argue it later.
