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 building regulations drawings in Lambeth.
Building regulations drawings for a Streatham project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Lambeth Council Building Control or an approved inspector. On SW16's victorian and edwardian terraces and bay-fronted semis, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Streatham, Norbury, Streatham Hill, Furzedown.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
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 building regulations drawings 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.
Housing stock in SW16: Victorian and Edwardian terraces and bay-fronted semis, with mansion blocks and larger villas around Streatham and Norbury.
Within the district: Streatham, Norbury, Streatham Hill, Furzedown.
Streets we know in SW16: the Streatham Hill and Telford Park roads, Mount Ephraim Lane and the Furzedown streets. Each road has its own building line, boundary treatment and precedent that Lambeth Council weighs when assessing a building regulations drawings scheme.
Conservation areas: Telford Park, Streatham Lodge, Leigham Court. Inside these, most external work needs full planning and a Heritage Statement.
Getting around SW16: Streatham, Streatham Hill and Streatham Common rail to Victoria and London Bridge.
Regeneration: Streatham falls within or beside the Streatham town centre regeneration, which shapes local planning policy and design expectations.
Property values: Streatham's postcode district saw 978 sales go through in 2025, median £467,500, down 2.1% on 2024. Lambeth holds under two-thirds of that trade and sales are also recorded in Wandsworth, Merton and Croydon, so treat any borough average as a rough proxy.

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 building regulations drawings 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.
Local policy varies more between adjoining boroughs than most owners expect. Full service detail for SE5, SE19, SE21, SE24, SE27, SW2, SW4 and SW9.

Every SW16 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. SW16 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the building regulations package before submitting SW16 drawings. |
| SW16 | Streatham | Edwardian terraces, post-war flats | A SW16 address in Streatham can route building control through Lambeth Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |
