Change-of-use drawings for Bexley — commercial to residential under Class MA, or a full application where the use classes do not line up — measured, drawn and evidenced for Bexley Council, with free revisions until your decision.
Bexley Council granted 88% of the householder planning decisions it made in its latest published year — 1 point above the 87% England-wide householder average. Green Belt at Crayford Marshes and Foots Cray Meadows tightly limits extensions on the borough's fringes, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) 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. Bexley carries at least one Article 4 direction, and conservation areas including Bexley Village, Danson Park and Upton remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Bexley is determined against an 8-week statutory target.
Old Bexley (the historic village strung along Bexley High Street), Bexleyheath (interwar semis around Danson Park and the Upton conservation area), Sidcup (1930s houses and older streets near Old Sidcup and Foots Cray), Erith (riverside terraces and postwar housing by the Thames), Crayford (Victorian and interwar homes along the industrial edge) and Welling (dense interwar semi-detached suburbs) — these are the Bexley pockets our drawings cover most. Heritage designations here include Bexley Village, Danson Park, Upton, Old Sidcup and Foots Cray. Bexley Council weighs each proposal against the Bexley Local Plan and the borough's design guidance for householder development, where hipped roofs on paired semis mean hip-to-gable and dormers are judged on bulk and the pair's balance. On roofs the borough is hipped roofs on the interwar and postwar semis and gabled roofs on the detached houses, over interwar and postwar semi-detached houses, detached houses on larger plots and riverside and Victorian terraces.
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. Bexley 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.
Bexley's stock is largely interwar and postwar semi-detached houses, detached houses on larger plots and riverside and Victorian terraces, and the buildings that come up for conversion here sit among Old Bexley, Bexleyheath, Sidcup and Erith — 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 Bexley Village, Danson Park, Upton, Old Sidcup and Foots Cray, the shopfront and frontage questions come back into play even on a prior-approval route. Bexley applies Article 4 directions in conservation areas such as Bexley Village and Danson Park, and parts of the borough fall within Metropolitan Green Belt where extensions are firmly restricted.
Green Belt at Crayford Marshes and Foots Cray Meadows tightly limits extensions on the borough's fringes, and hipped roofs on paired semis mean hip-to-gable and dormers are judged on bulk and the pair's balance. Both bear directly on a conversion: Bexley 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 Bexley 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 Bexley Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Bexley approves a strong majority of householder applications, with Metropolitan Green Belt on its edges and the symmetry of paired suburban semis the main factors shaping approvals. 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 Old Bexley, Bexleyheath and Sidcup, 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.
Green Belt at Crayford Marshes and Foots Cray Meadows tightly limits extensions on the borough's fringes. 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 Bexley. A few of the areas where conversions come up most often:
Change of use drawings for Old Bexley — the historic village strung along Bexley High Street — measured, laid out to space and daylight standards, and evidenced for Bexley Council.
Change of use drawings for Bexleyheath — interwar semis around Danson Park and the Upton conservation area — measured, laid out to space and daylight standards, and evidenced for Bexley Council.
Change of use drawings for Sidcup — 1930s houses and older streets near Old Sidcup and Foots Cray — measured, laid out to space and daylight standards, and evidenced for Bexley Council.
Change of use drawings for Erith — riverside terraces and postwar housing by the Thames — measured, laid out to space and daylight standards, and evidenced for Bexley Council.

Three routes, three different tests and three different timetables.
| Change | Route | Determination period | What Bexley 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 Bexley, 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 Bexley 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 Bexley 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. Bexley 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 Bexley address specifically. Bexley 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 Bexley address specifically. Bexley 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 Bexley address specifically. Bexley 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 Bexley address specifically. Bexley Council is the decision-maker.
