The party-wall route handled end to end for your Camden 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.
Camden Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. The council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) 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 Camden Council needs a full application. Camden carries at least one Article 4 direction, and conservation areas including Hampstead, Fitzroy Square and Bloomsbury remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Camden is determined against an 8-week statutory target.
Hampstead (Georgian and Victorian houses inside a tightly protected conservation area), Belsize Park (grand Victorian villas and red-brick mansion blocks), Camden Town (dense Victorian terraces around the market), Primrose Hill (pastel-painted Victorian terraces beside Regent's Park), Kentish Town (Victorian terraces and converted flats) and Bloomsbury (Georgian squares and formal terraces) — these are the Camden pockets our drawings cover most. Heritage designations here include Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill. Camden Council weighs each proposal against Camden Local Plan and the Camden Planning Guidance (CPG) on home improvements, where mansard and roof additions in conservation areas are measured against the terrace's original roofline and rhythm. Purpose-built mansion flats and converted terraces are widespread, and flats and maisonettes carry no householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs behind parapets and mansard roofs on the taller terraces, over Georgian and Victorian terraces, purpose-built mansion flats and converted period flats.
Camden is built wall-to-wall. Its Georgian and Victorian terraces, purpose-built mansion flats and converted period flats 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 Hampstead's Georgian and Victorian houses inside a tightly protected conservation area and the streets around Belsize Park, the same tight geometry is what makes party-wall matters so common. The council runs one of London's strictest basement regimes, capping depth and demanding a Basement Impact Assessment.
On the older terraces of Camden — in and around Hampstead, Fitzroy Square, Bloomsbury, Camden Town and Primrose Hill — 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. Much of Camden — the Hampstead and Fitzroy Square conservation areas among them — sits under Article 4 directions that strip out permitted-development rights, and the borough's basement rules pile on a further layer of control. 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 Hampstead, Belsize Park and Camden Town you must serve a party-wall notice on your Camden neighbour where any of these apply:
We assess whether the Act applies, serve the correct notices on every adjoining owner from Hampstead to Camden Town, 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 Camden build proceeds lawfully rather than stalling on a neighbour dispute.
Below is Camden Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Camden approves the large majority of householder applications, though its basement policy and dense conservation coverage are the decisive constraints on many schemes. 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 Hampstead, Belsize Park and Camden Town this is the sequence that keeps a build moving.
Mansard and roof additions in conservation areas are measured against the terrace's original roofline and rhythm. Getting the notice right first time matters, because an invalid notice can be challenged and set your Camden 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 Camden neighbourhoods where party-wall matters come up most often:
Party wall notices and awards for Hampstead's Georgian and Victorian houses inside a tightly protected conservation area — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Belsize Park's grand Victorian villas and red-brick mansion blocks — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Camden Town's dense Victorian terraces around the market — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Primrose Hill's pastel-painted Victorian terraces beside Regent's Park — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Kentish Town's Victorian terraces and converted flats — every adjoining owner identified and a schedule of condition prepared before work starts.
Party wall notices and awards for Bloomsbury's Georgian squares and formal terraces — 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 Camden — common around Hampstead and Fitzroy Square — 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 Camden 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 Hampstead and Belsize Park, 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 Belsize Park or wherever the Camden 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 Camden 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 Camden's georgian and victorian terraces around Hampstead and Camden Town. It is separate from planning permission: you can have full permission from Camden Council 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 victorian terraces. Serving valid notices first protects you as much as the neighbour. If you have already started a Camden project, we advise on the quickest lawful way to put it right. Camden Council 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 Camden project — especially on the dense streets around Belsize Park — keeps it off the critical path, and we flag the timing at the assessment. Camden Council 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 Camden Town. The award itself sets out who bears what. We are clear about the likely cost structure of your Camden matter at the outset, with no surprises later. Camden Council 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 victorian terraces common in Camden Town. It protects both sides: if the neighbour later claims your Camden 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. Camden Council is the decision-maker.
We price each Camden 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.
