Battersea (SW11) in Wandsworth runs from the prized 'between the commons' Victorian terraces near Clapham, through the shops of Lavender Hill and Northcote Road, down to the transformed Nine Elms riverside. On the terraced streets, side-return and rear extensions and loft conversions are the staple projects, and Wandsworth's design expectations for that consistent housing type are well documented.

Two conservation areas shape the district — Battersea Park around the park frontages, and the listed Shaftesbury Park Estate, a Victorian model-cottage estate where control over elevations and roofs is especially tight. We establish where a Battersea property sits relative to those boundaries, and the Thames flood zone near the river, before recommending a route and drawing to Wandsworth's residential guidance.

Planning in Battersea (SW11): what to know before you apply

SW11 has no householder Article 4 direction, so many Battersea terraces retain permitted development rights — but the Shaftesbury Park Estate model-cottage conservation area is a significant exception with tight elevation control, and riverside plots toward Nine Elms sit within the Thames flood zone.

Typical Battersea housing stock

Victorian terraces on the sought-after 'between the commons' streets and around Lavender Hill and Northcote Road, the listed Shaftesbury Park Estate model cottages, mansion flats facing Battersea Park, and new riverside apartments toward Nine Elms.

Wraparound Extension Drawings for Battersea (SW11) homes: the package and the process

Every wraparound extension drawings we prepare for an Battersea property is drawn to London Borough of Wandsworth’s validation standards and tuned to the SW11 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

A wraparound extension is what happens when a rear extension and a side return are designed together rather than as two separate projects: the new build wraps around the back corner of the house, turning a galley kitchen and a small rear room into one continuous kitchen, dining and living space running the full width of the plot. It is the most ambitious single-storey option most London terraces and semi-detached houses have, and because it reshapes almost the entire ground floor, it needs careful structural and drainage planning as well as a confident planning application.

DrawingsDirect draws wraparound extensions for full planning and building regulations, with structural calculations for the L-shaped frame and any drainage diversion produced in-house by our MCIAT-chartered team, on a fixed fee. If your project is a single-storey rear addition or a side infill on its own, see our Rear Extension and Side Return Extension pages; if you also want a second storey, see Double Storey Extension Drawings.

What makes a wraparound extension different from a rear or side return alone?

A rear extension adds depth at the back of the house; a side return adds width down the alley; a wraparound does both at once, so the new floor area turns the corner of the original building rather than sitting against just one wall. The result is typically the largest open-plan space a single-storey extension can deliver, but it also means more of the original external wall is removed and more of the roof is new, which raises the structural and drainage stakes compared with either extension on its own. Homeowners who start out planning a rear extension or a side return alone often move to a wraparound once they see how little extra it costs to combine the two, since much of the groundwork, roof structure and glazing is shared between them rather than duplicated.

Do wraparound extensions need full planning permission in London?

Almost always, yes. Permitted development allowances are calculated on combined additions to the original house, and a wraparound's depth plus width together generally exceed the volume and footprint limits that apply to a rear extension or side extension considered separately. A Lawful Development Certificate route is rarely viable for a genuine wraparound.

Conservation area status and Article 4 directions, common across the terraced streets where wraparound extensions are most popular, remove permitted development rights further still, so we design every wraparound on the assumption it will go through full householder planning.

FAQ

Wraparound Extension Drawings in Battersea SW11 — FAQs

How much does a wraparound extension cost to design in London?+
Wraparound extension drawings start from £2,200, covering full planning permission and structural design for the combined frame. Adding building regulations and construction detail brings the package to the Planning + Building Regs band, up to around £3,850, fixed and agreed upfront.
Does a wraparound extension always need planning permission?+
In almost every case, yes. The combined depth and width of a rear and side return together generally exceed permitted development limits, so we design wraparound projects on the assumption a full householder planning application is needed.
Do I need an architect for a wraparound extension?+
No. DrawingsDirect is an MCIAT-chartered architectural technologist practice, producing the same council-accepted drawings and structural coordination as an architect, for a fixed fee typically around 30% lower, with one team responsible for both the rear and side return elements rather than two separately briefed designers.
Will I need a Party Wall Agreement for a wraparound extension?+
Usually, because the side return element of a wraparound typically builds against or close to the boundary with the neighbouring property. We prepare the drawings your Party Wall surveyor needs alongside the planning application, timed so the notice period runs in parallel with the council's determination rather than adding to your overall timescale.
How long does it take to get wraparound extension drawings?+
Drawings are typically ready around 7 days from survey. A householder planning application then has a statutory 8-week determination period once submitted.
Do I need planning permission for a side-return extension in Wandsworth?+
On many of Wandsworth's Victorian terraces a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always required. Conservation areas such as Wandsworth Common and Nightingale Lane, and the 'between the commons' streets, can restrict this. We check your street's designation first and can secure a Lawful Development Certificate where the work is permitted development.
What does Wandsworth's basement Article 4 direction mean for me?+
In parts of Wandsworth an Article 4 direction removes permitted development for basement works, and the council requires a Basement Impact Assessment covering structural stability, drainage and groundwater. If you are considering a basement or lower-ground extension we flag whether the direction applies to your address early, and coordinate the structural input so the application is complete when submitted.
How long will Wandsworth take to decide my application?+
Wandsworth determines most householder applications within the statutory eight-week window once the submission is validated. Because the terraced grids around the commons are party-wall-sensitive and design expectations are well established, the commonest delay is a drawing query — so we prepare Wandsworth submissions to the validation checklist to keep them moving.
Can you design an extension for a converted flat near the commons?+
Yes. Much of Battersea and the streets around Clapham and Wandsworth Commons are mansion blocks and converted flats, where ownership, lease and party-wall considerations shape what is deliverable alongside the planning route. We confirm the ownership and structural context before drawing, and coordinate the calculations in-house so party-wall-sensitive schemes are handled cleanly.
How much do Wandsworth planning drawings cost?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Wandsworth approves. The price depends on the scheme — a side-return differs from a mansard loft or a basement — so we quote once we have seen your project rather than charging by the hour.
