Change-of-use drawings for Tower Hamlets — commercial to residential under Class MA, or a full application where the use classes do not line up — measured, drawn and evidenced for Tower Hamlets Council, with free revisions until your decision.
Tower Hamlets Council granted 92.1% of the householder planning decisions it made in its latest published year — 1.7999999999999972 points above the 90.3% England-wide householder average. Georgian frontages in Spitalfields are treated as near-untouchable, pushing any addition to the rear and out of public view, 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. Tower Hamlets carries at least one Article 4 direction, and conservation areas including Fournier Street, Elder Street and Narrow Street remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tower Hamlets is determined against an 8-week statutory target.
Spitalfields (early-Georgian silk-weavers' houses under strict conservation control), Bow (Victorian terraces around the Bow conservation area), Limehouse (riverside warehouse conversions along Narrow Street), Poplar (mixed Victorian terraces and postwar estates), Bethnal Green (dense Victorian terraces and former industrial buildings) and Mile End (Victorian terraces facing Mile End Park) — these are the Tower Hamlets pockets our drawings cover most. Heritage designations here include Fournier Street, Elder Street, Narrow Street, Victoria Park and Bow. Tower Hamlets Council weighs each proposal against Tower Hamlets Local Plan 2031 and the borough's Residential Alterations and Extensions guidance, where dense back-land plots make daylight, overlooking and outlook the decisive tests on rear projections. Much of the borough is flatted — split houses, ex-industrial units and dock conversions — so most homes here have no householder permitted-development rights.. On roofs the borough is parapet-hidden butterfly roofs on the Georgian terraces and pitched roofs on the Victorian stock, over Georgian merchant terraces around Spitalfields, Victorian terraces across Bow and Poplar and warehouse and dock conversions.
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. Tower Hamlets 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.
Tower Hamlets's stock is largely Georgian merchant terraces around Spitalfields, Victorian terraces across Bow and Poplar and warehouse and dock conversions, and the buildings that come up for conversion here sit among Spitalfields, Bow, Limehouse and Poplar — 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 Fournier Street, Elder Street, Narrow Street, Victoria Park and Bow, the shopfront and frontage questions come back into play even on a prior-approval route. The Spitalfields conservation areas around Fournier Street and Elder Street carry some of the tightest heritage controls in London, with Article 4 directions removing permitted-development rights on their early-Georgian frontages.
Georgian frontages in Spitalfields are treated as near-untouchable, pushing any addition to the rear and out of public view, and dense back-land plots make daylight, overlooking and outlook the decisive tests on rear projections. Both bear directly on a conversion: Tower Hamlets 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 Tower Hamlets 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 Tower Hamlets Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Tower Hamlets grants most householder applications, yet the exceptional heritage sensitivity of its Georgian quarters is the constraint that governs design more than anything else. 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 Spitalfields, Bow and Limehouse, 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.
Georgian frontages in Spitalfields are treated as near-untouchable, pushing any addition to the rear and out of public view. 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 Tower Hamlets. A few of the areas where conversions come up most often:
Change of use drawings for Spitalfields — early-Georgian silk-weavers' houses under strict conservation control — measured, laid out to space and daylight standards, and evidenced for Tower Hamlets Council.
Change of use drawings for Bow — Victorian terraces around the Bow conservation area — measured, laid out to space and daylight standards, and evidenced for Tower Hamlets Council.
Change of use drawings for Limehouse — riverside warehouse conversions along Narrow Street — measured, laid out to space and daylight standards, and evidenced for Tower Hamlets Council.
Change of use drawings for Poplar — mixed Victorian terraces and postwar estates — measured, laid out to space and daylight standards, and evidenced for Tower Hamlets Council.

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