Wandsworth Council operates a borough-wide Article 4 Direction removing permitted-development rights for HMO conversions. The classic SW11 'Between the Commons' Victorian terraces are prime side-return and rear-dormer territory, but several streets fall within the Battersea Park or Shaftesbury Park Estate conservation areas where full planning and a Heritage Statement are required.


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 Wandsworth.
Building regulations drawings for a Battersea project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Wandsworth Council Building Control or an approved inspector. On SW11's victorian and edwardian terraced houses around clapham, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Battersea, Clapham Junction, Between the Commons, Shaftesbury Estate, Nine Elms.
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 Battersea, Clapham Junction, Between the Commons, Shaftesbury Estate, Nine Elms in SW11, the dominant property is victorian and edwardian terraced houses around clapham common and the 'between the commons' grid, late-victorian mansion blocks along prince of wales drive, ex-industrial warehouse conversions near the river, and new-build riverside apartments at nine elms and battersea power station. 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 Wandsworth Council judges each on design quality and neighbour impact. We survey the specific Battersea property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW11 streetscape.

Yes — the 'Between the Commons' grid in SW11 (Battersea) is dominated by two-storey Victorian terraces with the classic narrow side return, which Wandsworth Council routinely approves under Permitted Development for single-storey rear and side-return additions up to 3m deep on attached houses. If your street sits within the Battersea Park or Shaftesbury Park Estate conservation area, full planning and a Heritage Statement are needed — we check your exact address first.
Parts of SW11 are. Battersea has three relevant conservation areas — Battersea Park, the Shaftesbury Park Estate, and the edge of Clapham Common — but the bulk of the 'Between the Commons' terraced streets and the Shaftesbury 'grid' are outside them. Inside a conservation area, roof extensions, rendering and replacement windows all need full planning. We confirm conservation status for your specific Clapham Junction or Battersea address before quoting.
On SW11's Victorian and Edwardian terraces a rear dormer or L-shaped dormer is the standard loft conversion, adding a double bedroom and bathroom while keeping the front roofline intact for the street scene. Mansard conversions are used where a fuller second-storey footprint is wanted and the terrace already has precedents. Building Regulations cover fire escape, floor structure and insulation; Party Wall notices to neighbours are almost always required for the steel beams.
With Battersea property at approx £650k–£1.4m for terraced houses, £475k–£900k for flats (Land Registry, 2024), the professional drawing fee is a small fraction of the value the work adds to SW11's victorian and edwardian terraced houses around clapham. Wandsworth Council charges its own statutory application fee on top (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 SW11 address.
For a SW11 project across Battersea, Clapham Junction, Between the Commons, Shaftesbury Estate, Nine Elms, 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 Wandsworth Council (8 weeks for a householder application). We carry the Battersea application through every officer query to the decision.
Battersea (SW11) sits primarily in Wandsworth, so applications are decided by Wandsworth Council. Conservation areas within SW11 include Battersea Park, Shaftesbury Park Estate, Clapham Common, 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 Battersea — 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 Wandsworth Council Building Control or an approved inspector. On SW11'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. With Battersea (SW11) property at approx £650k, £1.4m for terraced houses, £475k, £900k for flats (Land Registry, 2024), a well-designed extension or loft typically returns more than it costs in added floor area and sale value. 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 SW11 homes.
