Camden’s planning system sets a damage threshold, and it is a party wall one

Most planning policies talk about harm in general terms. Camden names a number, and the number comes from the same classification party wall surveyors use when they assess damage.

Policy A5 of the Camden Local Plan, adopted in July 2017, requires a Basement Impact Assessment

which shows that the scheme poses a risk of damage to neighbouring properties no higher than Burland Scale 1 ‘very slight’

That is unusual, and it matters here. The Burland scale classifies damage to buildings by severity, and category 1 sits near the bottom of it. A borough that writes a specific damage category into planning policy is regulating the same subject matter the Act regulates — the condition of the neighbouring building, and what the works may do to it — through a separate route.

The two remain distinct. The assessment is planning evidence prepared by consultants you appoint. An award is a statutory determination made by surveyors who, once appointed, are not acting as anyone’s representative. Neither substitutes for the other.

The council tells you to sort the party wall award first

Camden is unusually explicit about the relationship. Its Camden Planning Guidance: Basements, adopted 15 January 2021, sets out at paragraph 6.8:

For most basement developments applicants will need a party wall award… This includes when excavation is: within 3 metres of a neighbouring structure; would extend deeper than that structure’s foundations; or within 6 metres of the neighbouring structure and which also lies within a zone defined by a 45 degree line from that structure.

That is the council reciting section 6 of the Act, and note it states the three metre rule correctly — within three metres and deeper than the neighbour’s foundations, not distance alone.

Paragraph 6.9 draws the boundary: “The Council is not itself involved in Party Wall awards.”

Then paragraph 6.10 gives an ordering recommendation you will rarely see elsewhere:

The Council strongly recommends that Party Wall agreements are concluded prior to the applicant seeking the Council’s approval of the Basement Construction Plan (BCP).

So in Camden the party wall process is not an afterthought following planning permission. The council would rather you had it settled first.

Policy A5 adds a further point that touches the Act directly: “Given the complex nature of basement development, the Council encourages developers to offer security for expenses for basement development to adjoining neighbours.” Security for expenses is a mechanism the Act itself provides for.

Every basement needs planning permission here

A borough-wide Article 4 direction removes permitted development rights for basements. The sealed direction withdraws

The enlargement, improvement or other alteration of a dwellinghouse by carrying out below the dwellinghouse or its curtilage of basement or lightwell development, including the extension of an existing basement and any development integral to and associated with basement or lightwell development, being development comprised within Class A, Part 1 of Schedule 2 to the Order

and its second schedule covers “Land being the entire area of the London Borough of Camden”.

It was made under the Common Seal on 17 May 2016, confirmed on 3 October 2016, and came into force on 1 June 2017.

Camden is not alone in this — Kensington and Chelsea operates a comparable borough-wide direction, and its basement policy covers similar ground. What distinguishes Camden is the detail of Policy A5 rather than the mere fact of requiring permission.

For a listed building, the guidance notes that new basement development or extensions to existing basement accommodation will require listed building consent even where planning permission is not required.

The dimensional limits in Policy A5

Basement development should:

  • not comprise of more than one storey;
  • not be built under an existing basement;
  • not exceed 50 per cent of each garden within the property;
  • be less than 1.5 times the footprint of the host building in area;
  • extend into the garden no further than 50 per cent of the depth of the host building, measured from the principal rear elevation;
  • not extend into or underneath the garden further than 50 per cent of the depth of the garden;
  • be set back from neighbouring property boundaries where it extends beyond the footprint of the host building; and
  • avoid the loss of garden space or trees of townscape or amenity value.

Exceptions to several of these may be made on large comprehensively planned sites.

Three points of interpretation come from the 2021 guidance. A single storey is treated as “approximately 3 to 4 metres in height”, measured as the total depth of excavation. The 50 per cent garden rule applies to the front, rear and side gardens individually, not aggregated, and to the gardens as they currently exist. And the criteria are cumulative: “the area where a basement may be developed is the smallest of these areas.”

Where a basement extends beyond the building’s footprint, a minimum of one metre of soil is expected above it.

Policy A5 sets no numeric setback from neighbouring boundaries. Criterion l requires a set back without stating a distance, and the guidance says only that one will generally not be required where the neighbouring property’s own built form or basement already extends to the boundary. The distance question, in practice, is where the Act does its work rather than the plan.

The impact assessment is screened, then independently audited

Every basement proposal is screened. The guidance states that “All basement proposals should be subjected to the screening stage of a BIA”, covering groundwater flow, land stability, and surface flow and flooding. Where any screening question is answered yes or unknown, the matter needs further investigation; a no answer requires written justification.

A full assessment runs through five stages: screening, scoping, site investigation and study, impact assessment, and review and decision making.

Where a scheme proceeds beyond screening, or sits in an area of concern for slope stability, surface water or groundwater flow, independent verification follows — and the guidance is specific that “This independent verification will be commissioned by the Council.” Camden states that it obtains those independent audits from consulting engineers appointed for the purpose.

The guidance also sets mandatory qualifications for the authors, and will only accept those listed: chartered civil engineers and hydrologists for surface flow and flooding, chartered hydrogeologists for subterranean groundwater flow, and chartered civil engineers working with engineering geologists for land stability. A non-technical summary is expected, “presented in a format which can be fully understood by those with no technical knowledge”.

Consultation with local residents is expected on all basement developments unless the construction work is minimal and will have a negligible effect on adjoining or nearby properties.

One forward-looking caution. Camden has a new Local Plan at examination. Its draft basement policy would tighten the footprint rule so that a basement should not exceed the footprint of the host building, replacing the current 1.5 times allowance. Following hearings held in 2026 the Inspector has written to the council with actions, and any modifications would go to public consultation before a final report. Policy A5 remains the operative policy, but anyone planning a scheme close to the current limits should check the position before relying on them.

Flats, subdivided houses, and a great deal of listed stock

At Census 2021 Camden recorded 92,759 households:

  • 52,159 in a purpose-built block of flats or tenement
  • 24,284 in part of a converted or shared house, including bedsits
  • 7,504 in a terraced house
  • 3,294 in a semi-detached house
  • 2,213 in a commercial building
  • 1,650 in part of another converted building
  • 1,584 in a detached house

Around one household in seven lives in a house of any kind. As in other inner London boroughs, the party structure is frequently a floor rather than a wall.

The age profile is striking even by inner London standards: 50,900 properties built before 1900 and 4,050 between 1900 and 1918, from a total of 113,890 as at 31 March 2025. These Valuation Office Agency counts are rounded to the nearest ten by the agency, and count dwellings on the Council Tax list rather than households, so they do not share a denominator with the census figures above.

Heritage constraint follows from that age. Camden determined 404 householder development decisions in the year ending March 2026 and, in the same year, 402 listed building consents to alter or extend — the two run almost level, which is a fair measure of how much of the borough’s stock is listed. Those are decisions rather than grants; the published table does not break out grants for these categories.

Camden states there are 40 conservation areas in the borough, covering about half of it. Five conservation areas had new Article 4 directions confirmed in June 2026, withdrawing rights over front elevations, hard surfaces, boundary treatments and painting to varying extents. Their scope differs between areas, so it is worth checking the direction that applies to a specific address rather than assuming a common list.

Explain the property and proposed work

Provide:

  • the full property address;
  • whether the property is a house, a purpose-built flat or a flat in a converted house;
  • if a flat, which floors or ceilings are shared, and with whom;
  • whether a basement or lightwell is proposed or already exists, and the intended depth of excavation;
  • whether the property is listed or lies in a conservation area;
  • whether you are carrying out work or responding to a neighbour’s work;
  • a clear description of the proposed construction;
  • whether a Basement Impact Assessment has been screened or prepared, and by whom;
  • the freeholder and any leaseholder details, since more than one owner may need to be served;
  • drawings where available;
  • notices, responses and correspondence already exchanged; and
  • known dates and access constraints.

Compare the proposed appointment

Each quote should explain who would appoint the surveyor and the work included. That may involve reviewing drawings, notices, inspections, a schedule of condition, preparation of an award, liaison with another surveyor or later visits.

The party wall notice guide explains which notice applies to which work and how far ahead it must be served. The Party Wall surveyor guide explains when a surveyor may be needed, and the Party Wall surveyor cost guide explains the factors that can affect the proposed fee. Neighbouring coverage includes Party Wall surveyors for Islington properties, the address-boundary guide for Party Wall surveyors for Holborn properties, Party Wall surveyors for Hampstead properties and the wider Party Wall surveyor north London guide.

What happens after you post

The administrator reviews each complete enquiry before deciding whether to invite suitable qualified surveyors. Before selection, any invited surveyor receives only the outward postcode and a restricted, non-identifying brief.

If a quote is received and passes the administrative-completeness check, it is shown in the authenticated customer portal with the surveyor’s private documentary profile. Availability varies, so a request may receive several quotes, one, or none. Submission does not guarantee an invitation, quote or introduction.

If the administrator makes an introduction, only that surveyor receives your full contact and property details. FindTheSurveyor charges neither party a fee. You pay the professional fee directly to the surveyor.
