The party-wall route handled end to end for your Greenwich project — the right notices served on the neighbours, a schedule of condition to protect both sides, and a party-wall award agreed before work starts, so an extension, loft or basement proceeds lawfully and without dispute, with a free initial assessment of whether the Act even applies.
the Royal Borough of Greenwich granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The Maritime Greenwich World Heritage Site and its buffer zone add height and setting tests near the town centre, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which the Royal Borough of Greenwich needs a full application. Greenwich carries at least one Article 4 direction, and conservation areas including West Greenwich, Blackheath Park and Ashburnham Triangle remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Greenwich is determined against an 8-week statutory target.
Greenwich (Georgian and early-Victorian terraces inside the West Greenwich conservation area), Blackheath (villas and terraces around the Cator Estate and Blackheath Park), Westcombe Park (Edwardian and Victorian villas climbing the hill above the river), Charlton (the older cottages and interwar streets around Charlton Village), Eltham (interwar semis including the Well Hall Progress Estate) and Woolwich (denser Victorian terraces amid riverside regeneration) — these are the Greenwich pockets our drawings cover most. Heritage designations here include West Greenwich, Blackheath Park, Ashburnham Triangle, Westcombe Park and Charlton Village. the Royal Borough of Greenwich weighs each proposal against the Royal Greenwich Local Plan: Core Strategy with Detailed Policies and the borough's residential extensions design guidance, where protected Thames-side views shape what roof additions are acceptable on the borough's northern edge. On roofs the borough is parapet and butterfly roofs on the Georgian terraces and pitched and hipped roofs on the villas, over Georgian and early-Victorian terraces, Victorian and Edwardian villas and riverside and interwar housing.
Greenwich is built wall-to-wall. Its Georgian and early-Victorian terraces, Victorian and Edwardian villas and riverside and interwar housing share party walls the length of a street, so the loft conversions, side and rear extensions and basements that make these houses bigger nearly all touch a structure the neighbour half-owns. The Party Wall etc. Act exists precisely for this: it gives the building owner a lawful way to do the work and the adjoining owner a set of protections, and it runs entirely alongside — never instead of — the planning and building-control consents.
Three kinds of work bring the Act into play. Cutting into, raising or rebuilding a shared wall — a loft steel bearing on the party wall, a chimney removed — falls under the works notice. Building a new wall up to or astride the boundary engages the line-of-junction notice. And excavating within three metres of a neighbour's building and below its foundation level — routine for a basement or a deep extension footing — triggers the section 6 notice. On Greenwich's Georgian and early-Victorian terraces inside the West Greenwich conservation area and the streets around Blackheath, the same tight geometry is what makes party-wall matters so common. The Maritime Greenwich World Heritage Site and its buffer zone add height and setting tests near the town centre.
On the older terraces of Greenwich — in and around West Greenwich, Blackheath Park, Ashburnham Triangle, Westcombe Park and Charlton Village — the shared walls are frequently original and shared by more than one neighbour, so a single project can require notices on several adjoining owners at once. Article 4 directions strip out permitted-development rights across Greenwich's conservation areas such as West Greenwich and Westcombe Park, so front-facing and roof alterations there need a full application. We identify every adjoining owner and the correct notice for each before anything is served.

The Act is separate from planning permission — it applies to the building work itself, not the council decision. On streets like Greenwich, Blackheath and Westcombe Park you must serve a party-wall notice on your Greenwich neighbour where any of these apply:
We assess whether the Act applies, serve the correct notices on every adjoining owner from Greenwich to Westcombe Park, prepare a photographic schedule of condition that protects both sides, and — where the neighbour dissents — act as party-wall surveyor to agree an award before work starts, so your Greenwich build proceeds lawfully rather than stalling on a neighbour dispute.
Below is the Royal Borough of Greenwich's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Greenwich approves most householder applications, but the Maritime Greenwich World Heritage Site and its dense conservation coverage set the terms for what works near the town centre and the river. Party-wall matters run alongside these permissions rather than through them — but the volume of extensions and lofts approved here is the volume of projects that will need notices served on a neighbour.

The process has a clear shape. You serve notice on the adjoining owner, giving the required period — a month for line-of-junction and excavation notices, two months for works to the wall itself. The neighbour then consents, dissents, or stays silent (which counts as dissent). If they consent, a schedule of condition still protects both parties. If they dissent, a surveyor is appointed — one agreed surveyor for both, or one each — to settle a party-wall award: the document that records the condition of the neighbour's property, sets out how and when the work proceeds, and provides the route to resolve any damage. Across Greenwich, Blackheath and Westcombe Park this is the sequence that keeps a build moving.
Protected Thames-side views shape what roof additions are acceptable on the borough's northern edge. Getting the notice right first time matters, because an invalid notice can be challenged and set your Greenwich start date back by months, and starting work without one exposes you to an injunction. We serve valid notices, record the neighbour's property honestly in the schedule of condition, and where surveyors are appointed we act firmly but proportionately — the award should let the work happen, not stall it.

We handle notices, schedules and awards on the tight terraced and semi-detached streets across the borough. A few of the Greenwich neighbourhoods where party-wall matters come up most often:
Party wall notices and awards for Greenwich's Georgian and early-Victorian terraces inside the West Greenwich conservation area — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Blackheath's villas and terraces around the Cator Estate and Blackheath Park — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Westcombe Park's Edwardian and Victorian villas climbing the hill above the river — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Charlton's the older cottages and interwar streets around Charlton Village — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Eltham's interwar semis including the Well Hall Progress Estate — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Woolwich's denser Victorian terraces amid riverside regeneration — every adjoining owner identified and a schedule of condition prepared before work starts.
The Act sets out three notice types by the kind of work. This is which applies, the notice period, and the typical project behind it.
| Notice | Triggered by | Notice period | Typical project |
|---|---|---|---|
| Section 2 works | Cutting into, raising or rebuilding a shared wall | Two months | Loft steel, extension, chimney removal |
| Line of junction | A new wall up to or astride the boundary | One month | Side or rear extension flank wall |
| Section 6 excavation | Digging within 3m and below the neighbour's foundations | One month | Basement, deep extension footing |
| Schedule of condition | Recording the neighbour's property beforehand | Before work | Every party-wall project |
On an end-terrace or corner property in Greenwich — common around West Greenwich and Blackheath Park — a single project can require several of these notices served on different adjoining owners at once.
A fixed sequence that keeps the neighbour onside and the build lawful — the assessment is free, so you know whether the Act even applies before committing.
Tell us the Greenwich project and where it sits relative to the neighbours. We confirm whether the Party Wall Act applies, which notices are needed and on how many adjoining owners.
We prepare and serve the correct valid notices on every adjoining owner across Greenwich and Blackheath, with the required notice period, so the clock starts cleanly and cannot be challenged as defective.
Before work starts we prepare a dated, photographic schedule of condition of the neighbour's property in Blackheath or wherever the Greenwich project sits, so any later damage claim can be judged against a clear record that protects both sides.
Where a neighbour dissents we act as party-wall surveyor to agree an award setting out how the work proceeds, then remain available through the Greenwich build to resolve any issue that arises.
You do wherever your work touches a shared wall or excavates near a neighbour — which covers most loft conversions, side and rear extensions and all basements on Greenwich's georgian and early-victorian terraces around Greenwich and Westcombe Park. It is separate from planning permission: you can have full permission from the Royal Borough of Greenwich and still be legally required to serve a party-wall notice. Our free assessment confirms whether the Act applies to your specific project before anything is served.
You expose yourself to real risk. A neighbour can seek an injunction to stop the work, and without a schedule of condition you have no agreed record to defend a damage claim, so you may end up paying for pre-existing cracks in their georgian and early-victorian terraces. Serving valid notices first protects you as much as the neighbour. If you have already started a Greenwich project, we advise on the quickest lawful way to put it right. the Royal Borough of Greenwich is the decision-maker.
Build the notice period into your programme: a line-of-junction or excavation notice needs one month, and a notice for works to the wall itself needs two months, before work can start. If the neighbour consents quickly the process ends there; if they dissent, agreeing an award typically adds a few more weeks. Starting the party-wall route early in your Greenwich project — especially on the dense streets around Blackheath — keeps it off the critical path, and we flag the timing at the assessment. the Royal Borough of Greenwich is the decision-maker.
As a rule the building owner — the person doing the work — pays the reasonable surveyors' costs, because they are the one benefiting from the project. That usually includes the adjoining owner's surveyor's fee where the neighbour dissents and appoints their own — common on the shared party walls around Westcombe Park. The award itself sets out who bears what. We are clear about the likely cost structure of your Greenwich matter at the outset, with no surprises later. the Royal Borough of Greenwich is the decision-maker.
A schedule of condition is a dated, photographic record of the adjoining property's state before your work begins — walls, ceilings, existing cracks and finishes — particularly valuable on the older georgian and early-victorian terraces common in Westcombe Park. It protects both sides: if the neighbour later claims your Greenwich build caused damage, the schedule shows what was already there, and it reassures the neighbour that genuine new damage will be put right. We prepare it thoroughly before any work starts, whether or not the neighbour has dissented. the Royal Borough of Greenwich is the decision-maker.
We price each Greenwich matter individually, because the number of adjoining owners, whether they consent or dissent and the complexity of the work all vary, and give a clear indication after the free assessment. A simple consented notice with a schedule of condition is modest; a dissented award with surveyors on both sides costs more, and the building owner usually bears the reasonable fees.
