Party Wall Surveyor Putney

Putney’s planning evidence changes over short distances: a property may be outside a conservation area, inside one of several separately named designations, or among the small set of Commondale addresses subject to a specific Article 4 direction. The Party Wall analysis is a further, independent exercise based on the wall, structure, excavation geometry and foundation evidence.

FindTheSurveyor is a neutral marketplace and does not carry out Party Wall surveying. The administrator reviews a request before any potential invitation or introduction. Posting does not guarantee an invitation, quote or introduction.

Putney has several conservation records, not one

Wandsworth’s current conservation-area appraisal directory contains separate entries for East Putney, Oxford Road, Putney Embankment, Putney Heath, Putney Lower Common and West Putney. Those names refer to mapped designations with different character evidence. They cannot be replaced by a generic “Putney conservation area” statement.

Record the designation shown for the exact address and use its own appraisal. That is particularly important for a proposal involving a front lightwell, boundary treatment, visible excavation enclosure, tree or change to the relationship between a house and its garden. Conservation status is a planning constraint; it does not show that a neighbouring wall is shared or that section 6 applies.

The Party Wall surveyor West London guide sets the regional context. The borough-wide adopted-policy position is covered for Party Wall surveyors for Wandsworth properties.

The Commondale direction does not cover all Putney

Wandsworth’s current Article 4 register includes Putney Lower Common, but the linked area page is expressly headed for 15 to 36 Commondale. It lists specified visible exterior alterations, roof and porch changes, hard surfacing in front and some side garden areas, boundaries facing a road or footpath, demolition of a front boundary or buildings, and external painting.

That is a useful guard against two opposite errors. An address elsewhere in Putney should not be treated as covered merely because the locality name matches. An address within the stated range should not assume that every kind of development is withdrawn: the proposed operation must be checked against the direction itself. Planning permission resulting from Article 4 is not an adjoining owner’s consent and does not start a Party Wall notice period.

LP6 survived the 2026 Partial Review

The council’s Local Plan page records adoption of the Wandsworth Local Plan 2023–2038 on 19 July 2023 and adoption of a Partial Review on 4 March 2026. The review replaced six housing policies—LP23, LP24, LP28, LP29, LP30 and LP31—but left LP6, Basements and Subterranean Developments, in force.

Under the current adopted Local Plan, a residential basement proposal should show all of the following LP6 matters rather than only its overall footprint:

no more than one storey of basement accommodation below ground;
no more than 50% of the existing rear garden or other undeveloped garden area, excluding the original building and other permanent structures, beneath the development;
at least one metre of naturally draining permeable soil plus a minimum 200mm drainage layer above any basement beneath a garden;
a satisfactory landscaping scheme and the required natural light and ventilation for habitable accommodation; and
flood-risk evidence and a positive pumped device or equivalent for sewer-flood mitigation.

LP6 has a separate front-lightwell measurement. Inside a conservation area the retained original front-garden depth must be at least two metres or 50%, whichever is greater. Elsewhere in Wandsworth it must be at least 50%. A Putney drawing should therefore identify the original garden extent, the current mapped designation and the proposed lightwell edge.

None of those figures determines the Party Wall result. The unexcavated garden percentage is not the horizontal distance to an adjoining building, and one metre of soil plus drainage is not the adjoining foundation-bottom level.

Keep the four statutory categories exact

The Party Wall surveyor guide explains the statutory roles. Apply the following work-specific checks before deciding what notice route is relevant:

Section 1: it applies where differently owned lands adjoin and the line is unbuilt or built on only by a boundary wall that is neither a party fence wall nor the external wall of a building, and an owner is about to build on part of that line. Notice describing the intended wall is served at least one month before work starts. Without the adjoining owner’s consent to the new party wall or party fence wall, the building owner may build only wholly on their own land and at their own expense.
Sections 2 and 3: the building owner ordinarily gives at least two months’ party-structure notice before exercising a section 2 right. Section 3(3) allows the right to be exercised with the adjoining owners’ and occupiers’ written consent and does not require notice before compliance with a statutory dangerous-or-neglected-structure notice. The specific section 2 right exercised—not the project label—controls the classification.
Section 6(1): the first limb is a horizontal distance within three metres of part of an adjoining building or structure. The second must also be met: part of the proposed excavation, building or structure within those three metres extends below the level of the bottom of that adjoining building or structure’s foundations.
Section 6(2): within six metres, the separate condition is whether any part of the proposed excavation, building or structure would meet a plane drawn downwards in the direction of the building owner’s excavation, building or structure at 45 degrees to the horizontal. The plane runs from the line formed where the plane at the adjoining foundation-bottom level intersects the plane of the external face of the adjoining external wall.

If section 6 applies, at least one month’s notice is required before excavation, accompanied by the prescribed plans and sections. The party wall notice guide explains the different notices and response routes. An LP6 assessment, conservation approval or Article 4 application cannot replace those statutory documents.

Give each Putney quote the same evidence set

Start with the complete address, conservation-area result and any Commondale Article 4 result. Provide existing and proposed plans, original and proposed garden measurements, a section through the excavation, the horizontal distance to each adjoining building or structure and available information about the adjoining foundations. Identify separately any cutting-in, raising, underpinning, rebuilding, chimney-breast removal or other work to a shared structure.

Add the planning record, drainage and structural information, notices and responses already exchanged, relevant ownership interests and intended start date. Unknown foundation information should remain marked as unknown until assessed. The Party Wall surveyor cost guide helps define comparable appointment components without assuming what an unexamined job requires. If introductions are available and the administrator records your chosen introduction, compare the written scope, documents, inspections and exclusions. Post your Putney Party Wall job.

Sources checked

The plan-status, basement, conservation and Article 4 statements were checked against the linked Wandsworth Council material on 24 August 2026. The statutory wording was checked against section 1, section 2, section 3 and section 6 of the Party Wall etc. Act 1996. Recheck the address, policy status and mapped controls when the work is prepared.
