Change-of-use drawings for Southwark — commercial to residential under Class MA, or a full application where the use classes do not line up — measured, drawn and evidenced for Southwark Council, with free revisions until your decision.
Southwark Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. Mansards and roof extensions on terraces are assessed against the established roofline and the conservation-area appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Southwark carries at least one Article 4 direction, and conservation areas including Camberwell Grove, Dulwich Village and Bermondsey Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Southwark is determined against an 8-week statutory target.
Camberwell (Georgian and Victorian terraces around Camberwell Grove), Dulwich (villas and the Dulwich Village conservation area under the Dulwich Estate), Bermondsey (warehouse conversions and terraces off Bermondsey Street), Peckham (Victorian terraces including the Holly Grove enclave), Nunhead (modest Victorian terraces near Nunhead Green and the cemetery) and Walworth (dense Georgian and Victorian terraces threaded through large estates) — these are the Southwark pockets our drawings cover most. Heritage designations here include Camberwell Grove, Dulwich Village, Bermondsey Street, Holly Grove and Nunhead Green. Southwark Council weighs each proposal against the Southwark Plan and the borough's Residential Design Standards SPD, where the borough runs detailed basement and residential design standards on top of the usual tests. Camberwell, Peckham and the warehouse quarters around Bermondsey are heavily subdivided into flats, none of which hold householder permitted-development rights.. On roofs the borough is butterfly and parapet roofs on the terraces and flat and pitched roofs on the former warehouses, over Georgian and Victorian terraces, former warehouse and industrial conversions and Dulwich villas and postwar estates.
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. Southwark 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.
Southwark's stock is largely Georgian and Victorian terraces, former warehouse and industrial conversions and Dulwich villas and postwar estates, and the buildings that come up for conversion here sit among Camberwell, Dulwich, Bermondsey and Peckham — 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 Camberwell Grove, Dulwich Village, Bermondsey Street, Holly Grove and Nunhead Green, the shopfront and frontage questions come back into play even on a prior-approval route. Southwark carries numerous Article 4 directions across conservation areas such as Camberwell Grove and Bermondsey Street, while the Dulwich Estate's scheme of management adds a separate layer of consent in Dulwich.
Mansards and roof extensions on terraces are assessed against the established roofline and the conservation-area appraisal, and the borough runs detailed basement and residential design standards on top of the usual tests. Both bear directly on a conversion: Southwark 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 Southwark 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 Southwark Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Southwark grants most householder applications, but heavy conservation-area coverage, its basement policies and the Dulwich Estate's scheme of management dictate what is achievable in many neighbourhoods. 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 Camberwell, Dulwich and Bermondsey, 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.
Mansards and roof extensions on terraces are assessed against the established roofline and the conservation-area appraisal. 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 Southwark. A few of the areas where conversions come up most often:
Change of use drawings for Camberwell — Georgian and Victorian terraces around Camberwell Grove — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Change of use drawings for Dulwich — villas and the Dulwich Village conservation area under the Dulwich Estate — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Change of use drawings for Bermondsey — warehouse conversions and terraces off Bermondsey Street — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Change of use drawings for Peckham — Victorian terraces including the Holly Grove enclave — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Change of use drawings for Nunhead — modest Victorian terraces near Nunhead Green and the cemetery — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Change of use drawings for Walworth — dense Georgian and Victorian terraces threaded through large estates — measured, laid out to space and daylight standards, and evidenced for Southwark Council.
Three routes, three different tests and three different timetables.
| Change | Route | Determination period | What Southwark 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 Southwark, 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 Southwark 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 Southwark 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. Southwark 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 Southwark address specifically. Southwark 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 Southwark address specifically. Southwark 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 Southwark address specifically. Southwark 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 Southwark address specifically. Southwark Council is the decision-maker.
