Party Wall Services · SW16 Streatham
SW16 spans Lambeth and Croydon; Lambeth controls the Telford Park and Leigham Court conservation areas around Streatham.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read party wall services in Lambeth.
Party Wall services in Streatham cover the notices and awards required when you build near or on a shared wall — almost universal on SW16's terraced and semi-detached houses. Before steel beams, loft conversions or basement work, adjoining owners across Streatham, Norbury, Streatham Hill, Furzedown must be served the correct notices; we prepare them with a schedule of condition.
End-to-end Party Wall Act 1996 service for Streatham — Section 1, 3 and 6 notices, schedule of condition surveys, party wall award coordination. We handle the process so your Streatham build starts without neighbour disputes.
Across Streatham, Norbury, Streatham Hill, Furzedown in SW16, the dominant property is victorian and edwardian terraces and bay-fronted semis, with mansion blocks and larger villas around streatham and norbury. 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 Lambeth Council judges each on design quality and neighbour impact. We survey the specific Streatham property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW16 streetscape.

We review your Streatham 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 Streatham 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.
Yes. The Victorian and Edwardian terraces and bay-fronted semis around Telford Park and Furzedown suit side-return and rear extensions plus loft conversions, much of it within Permitted Development outside the conservation areas, confirmed with a Lawful Development Certificate. We confirm the route and draw to Lambeth's checklist.
SW16 straddles the boundary — Streatham and Streatham Hill sit in Lambeth, while Norbury falls into Croydon. The two councils apply different conservation and householder controls, so we confirm your exact authority before quoting and submit accordingly.
Usually yes — a hip-to-gable plus rear dormer on the semis, within the volume allowance and confirmed by a Lawful Development Certificate, provided you're not in the Telford Park or Leigham Court conservation areas. We check the constraints for your road and draw it for Building Control.
With SW16 houses around £700,000-£1m and Streatham's town-centre regeneration improving the area, a well-designed rear extension or loft adds family space worth comfortably above the build and drawing cost.
Lambeth Council charges its own statutory application fee (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 SW16 address.
For a SW16 project across Streatham, Norbury, Streatham Hill, Furzedown, 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 Lambeth Council (8 weeks for a householder application). We carry the Streatham application through every officer query to the decision.
Streatham (SW16) sits primarily in Lambeth, so applications are decided by Lambeth Council. Conservation areas within SW16 include Telford Park, Streatham Lodge, Leigham Court, 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 Streatham — 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 Lambeth Council Building Control or an approved inspector. On SW16'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 SW16 homes.
Householders often approach us after a neighbour used a different council. Our full range is set out for SE5, SE19, SE21, SE24, SE27, SW2, SW4 and SW9.
