Change-of-use drawings for Wandsworth — commercial to residential under Class MA, or a full application where the use classes do not line up — measured, drawn and evidenced for Wandsworth Council, with free revisions until your decision.
Wandsworth Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Wandsworth carries at least one Article 4 direction, and conservation areas including Wandsworth Common, Nightingale Triangle and Tonsleys remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wandsworth is determined against an 8-week statutory target.
Battersea (Victorian terraces and mansion flats near the park), Balham (Edwardian terraces around the Nightingale Triangle), Tooting (long Victorian terraces off the high road), Putney (Edwardian villas and riverside streets), Earlsfield (compact Victorian terraces between the commons) and Southfields (the Magdalen Park grid of Edwardian houses) — these are the Wandsworth pockets our drawings cover most. Heritage designations here include Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park. Wandsworth Council weighs each proposal against Wandsworth Local Plan and the borough's Housing and Basements SPDs, where the borough applies detailed basement-development policies on top of the usual tests. Much of Battersea and Balham is converted flats and maisonettes, which carry no householder permitted-development rights.. On roofs the borough is butterfly / valley roofs on the terraces and pitched roofs on the villas, over Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas.
The 2020 amendments to the Use Classes Order collapsed shops, offices, cafés, gyms and clinics into a single Class E, so movement between those uses is generally not development at all and needs no application. What still bites is the move out of Class E — most importantly into residential — and the uses that sit outside the class system altogether, such as houses in multiple occupation, pubs, takeaways and betting shops, each of which is sui generis or in its own class.
Class MA gives a prior-approval route from Class E to dwellings. Wandsworth Council cannot refuse it on general planning-policy grounds, but it can and does assess a defined list: transport, contamination, flooding, noise from nearby commercial premises, natural light to all habitable rooms, and the impact of losing a ground-floor service use in a designated area. The qualifying conditions are strict — two years in Class E use, three months vacant, and a floorspace cap — and evidence of those facts is part of the submission, not an afterthought.
Wandsworth's stock is largely Victorian terraces, Edwardian mansion flats and Putney and Wandsworth villas, and the buildings that come up for conversion here sit among Battersea, Balham, Tooting and Putney — which is why the noise and amenity questions differ street by street rather than following a district-wide rule. Where the building sits in a conservation area such as Wandsworth Common, Nightingale Triangle, Tonsleys, Magdalen Park and Battersea Park, the shopfront and frontage questions come back into play even on a prior-approval route. Several Wandsworth conservation areas carry Article 4 directions, and the borough's dense conservation coverage means many terraced streets need a full application for works that would be PD elsewhere.
Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline, and the borough applies detailed basement-development policies on top of the usual tests. Both bear directly on a conversion: Wandsworth Council reads the resulting homes against the same amenity expectations it applies to new build, so the layout has to stand up as housing before the prior-approval matters are even reached.
Movement within Class E is usually not development. You will need prior approval or a full application from Wandsworth Council where any of these apply:
We measure the building as existing, draw the proposed layout to habitable-room and daylight standards, and assemble the qualifying evidence — use history, vacancy, floorspace — so the prior-approval clock starts on a complete submission.
Below is Wandsworth Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Wandsworth grants a healthy share of householder applications, but its uniform Victorian terraces mean side returns and roof alterations are assessed in centimetres against the neighbours. Prior-approval applications are decided against a fixed list of matters, so a submission that answers each one directly is the one that gets through.

Across Battersea, Balham and Tooting, the conversions that go through are the ones that treat the resulting homes as homes: every habitable room with adequate natural light, room sizes meeting the nationally described space standards, sensible refuse and cycle provision, and a considered answer on noise where the neighbouring units are still commercial. Natural light is the single most common reason a Class MA prior approval is refused, and it is a drawing problem before it is a policy problem.
Side returns, mansards and dormers are judged in centimetres against the party wall and shared roofline. Where the building does not qualify for Class MA — because of its use history, its floorspace or a local Article 4 direction — a full application is the honest route, and we say so at the outset rather than burning 56 days on a prior approval that was never going to be granted.
We prepare change-of-use submissions across Wandsworth. A few of the areas where conversions come up most often:
Change of use drawings for Battersea — Victorian terraces and mansion flats near the park — measured, laid out to space and daylight standards, and evidenced for Wandsworth Council.
Change of use drawings for Balham — Edwardian terraces around the Nightingale Triangle — measured, laid out to space and daylight standards, and evidenced for Wandsworth Council.
Change of use drawings for Tooting — long Victorian terraces off the high road — measured, laid out to space and daylight standards, and evidenced for Wandsworth Council.
Change of use drawings for Putney — Edwardian villas and riverside streets — measured, laid out to space and daylight standards, and evidenced for Wandsworth Council.
Change of use drawings for Earlsfield — compact Victorian terraces between the commons — measured, laid out to space and daylight standards, and evidenced for Wandsworth Council.

Three routes, three different tests and three different timetables.
| Change | Route | Determination period | What Wandsworth Council assesses |
|---|---|---|---|
| Shop to café or office (within Class E) | Not development — no application | n/a | Nothing, unless conditions restrict use |
| Class E to dwellings | Class MA prior approval | 56 days | Transport, flooding, contamination, noise, natural light |
| Class E to dwellings, not qualifying | Full planning application | 8 weeks (13 for major) | Full policy assessment |
| House to small HMO | Class L, unless Article 4 applies | n/a or 8 weeks | Concentration, amenity, parking |
| Anything to sui generis use | Full planning application | 8 weeks | Amenity, hours, highways |
Routes from the Town and Country Planning (Use Classes) Order 1987 as amended in 2020, and the GPDO 2015, Schedule 2, Part 3, Class MA.
A process built around the qualifying evidence, not just the drawings.
Tell us the current use, how long it has run and what you want to do. We confirm the use classes, whether Class MA is available in Wandsworth, and whether an Article 4 direction removes it.
We measure the building as existing, including window positions and floor-to-ceiling heights, because the daylight and space-standards case depends on real dimensions.
We draw the proposed layouts to space and daylight standards and assemble the use-history, vacancy and floorspace evidence Wandsworth Council needs to validate the submission.
We submit, track the determination period, answer officer queries and revise free until the decision is issued.
It depends on the use classes. Moving between uses inside Class E — shop, office, café, gym, clinic — is generally not development and needs no application to Wandsworth Council. Moving out of Class E, particularly into residential, needs either prior approval under Class MA or a full application. We establish which applies before any drawing work, because the routes have different evidence requirements.
Class MA is the permitted-development right that allows Class E commercial, business and service premises to become dwellings. Wandsworth Council assesses a defined list of matters — transport, contamination, flooding, noise, natural light and, in some designated areas, the loss of a ground-floor service use — and must determine within 56 days. It cannot refuse on general policy grounds, which is why it is a faster route where the building qualifies.
The building must have been in Class E use for at least two years before the application, and must have been vacant for at least three months immediately before it. There is also a floorspace cap, and the right is disapplied on certain protected land and where an Article 4 direction removes it. Evidence of use history and vacancy forms part of the submission — a bare assertion will not validate. This applies to your Wandsworth address specifically. Wandsworth Council is the decision-maker.
Yes, and it is the most common reason Class MA prior approvals fail. Every habitable room must have adequate natural light, and deep commercial floorplates frequently cannot deliver it without new openings or a reduced unit count. We test it on the layout first, because discovering it after submission costs a full determination period. This applies to your Wandsworth address specifically. Wandsworth Council is the decision-maker.
Almost always where the use becomes residential. A material change of use triggers requirements for fire safety and means of escape, sound insulation between units under Part E, ventilation, and thermal performance. Planning and building control are separate consents — we prepare both so the scheme that is approved is the scheme that can be built and signed off. This applies to your Wandsworth address specifically. Wandsworth Council is the decision-maker.
A Class MA prior approval must be determined within 56 days of a valid submission, and the application is deemed approved if the council fails to decide in time — which makes validation completeness unusually valuable. A full application runs to the standard eight-week target, or thirteen weeks if it counts as a major development. This applies to your Wandsworth address specifically. Wandsworth Council is the decision-maker.
