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.

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

Every house 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 well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.

Which extension types do you draw?

Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.

Rear extension

A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.

Side-return

Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.

Wraparound

Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.

Double-storey

Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.

Basement

Creates space downward where footprint is limited, with structural and party-wall care.

Do I need planning permission for a house extension in London?

Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing.

FAQ

House Extension Drawings in Battersea SW11 — FAQs

How far can I extend without planning permission in London?+
Under permitted development, single-storey rear extensions can reach 3m (terraced/semi) or 4m (detached), or up to 6–8m under the prior-approval larger-home scheme — but conservation areas and Article 4 directions can remove these rights. We check your property first.
Do extension drawings include structural calculations?+
Our full package includes structural drawings and calculations coordinated in-house, so your builder can price and build without waiting on an engineer.
How long do extension drawings take?+
Typically about 7 days from survey to a full drawing set delivered to your online portal.
Will my rear extension need a party wall agreement?+
If you build up to or on a shared boundary, excavate near a neighbour's foundations, or cut into a party wall for a steel, the Party Wall etc. Act 1996 usually applies. Our drawings show the works clearly so a party wall surveyor — or your neighbour — can see exactly what is proposed, which keeps that process quick.
Can I extend a house in a conservation area?+
Yes, but conservation areas and Article 4 directions commonly remove permitted development for rear and side extensions, so the work needs a full householder application designed to the council's heritage guidance. We confirm your property's designation before recommending a route.
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.
