Change of Use Drawings in Tower Hamlets
Fixed-fee, MCIAT-chartered change of use drawings for Tower Hamlets homeowners — London Borough of Tower Hamlets validation and local constraints handled from the start.
Tower Hamlets runs from the listed Georgian terraces of Spitalfields and the warehouse and wharf conversions of Wapping and Limehouse through the Victorian streets of Bow and Mile End to the dense purpose-built and estate housing of Bethnal Green, Poplar and Whitechapel and the towers of the Isle of Dogs. It is one of London's most heritage-dense and design-scrutinised boroughs, so the right route for an alteration or extension depends heavily on the building type and its conservation or listing status.
A high proportion of streets fall within conservation areas — Fournier Street and Elder Street in Spitalfields, Wapping Pierhead, Narrow Street in Limehouse, Victoria Park, Tredegar Square in Bow and Whitechapel Market — where permitted development is removed and even some changes of use are controlled. Spitalfields in particular carries a high density of listed Georgian terraces, where listed-building consent is usually required for many alterations, internal as well as external. Tower Hamlets also applies Article 4 directions removing permitted development for HMO conversions in parts of the borough, Thames-side flood-zone considerations run along the Wapping and Limehouse riverside, and tall-building and townscape context near the City fringe and Canary Wharf adds further design scrutiny.
We prepare Tower Hamlets planning and, where needed, listed-building submissions to the council's validation and design standards, screening conservation-area and listing constraints for your exact address before recommending a route to consent. Because the borough determines most householder applications within the statutory eight-week period once validated, we work validation-first to avoid the queries that cause most delays. The fee is fixed and agreed up front, drawings typically follow within about seven days, and we offer free redraws until the council approves — the same council-accepted drawings an architect would produce, usually at around 30% less.
Planning in Tower Hamlets: what to know before you apply
Tower Hamlets applies Article 4 directions to HMO conversions in parts of the borough and removes permitted development across its many conservation areas — Spitalfields, Wapping Pierhead and Tredegar Square among them. Spitalfields in particular carries a high density of listed Georgian terraces where listed-building consent is usually required. Thames flood-zone considerations apply along the riverside. We confirm the constraints for your address before drawing.

What the numbers say about Tower Hamlets planning decisions
These are London Borough of Tower Hamlets’s own reported figures, published by government rather than estimated by us. They are what we design against — a borough that refuses one householder application in five needs a different drawing package from one that refuses one in twenty.

Change of Use Drawings for Tower Hamlets homes: the package and the process
A change of use application is decided on what the building is, what it becomes, and what that changes. The drawings show the existing use class layout and the proposed one at the same scale, with a floor area schedule for each so the officer can see exactly what is moving between uses.
The supporting drawings usually matter as much as the plans. Access, parking, servicing arrangements, refuse storage and any external alteration all get drawn, because the objections to a change of use are rarely about the internal layout — they are about what the new use does to the street.
The building's form limits what it can honestly become. A ground-floor unit with its own frontage converts to residential more readily than upper floors reached through a shared entrance, and a deep plan with windows on one elevation only will struggle to give a habitable room adequate light whatever the policy position.
What counts as a material change of use?
Not every change in how a building is used needs planning permission — only a 'material' change, one significant enough to affect the character of the use of the land. Converting a single dwellinghouse into two or more flats is always material. Adding paying lodgers within a single household usually is not, until the household tips over into a small House in Multiple Occupation. We assess whether your proposed change crosses that threshold before recommending a route.
The Use Classes Order: C3, C4, E and sui generis
The Use Classes Order groups uses so planners, and permitted development rules, can treat similar activities consistently.
C3 — Dwellinghouses
The class covering a single household living as a single unit, including up to two people living together as a single household who are not related. Most family homes and self-contained flats fall here.
C4 — Houses in multiple occupation (small)
Covers a shared house or flat occupied by three to six unrelated people sharing basic amenities such as a kitchen or bathroom. Moving from C3 to C4 is a change of use, though it is often permitted development unless your borough has removed that right.
Class E — Commercial, business and service
A wide class combining shops, offices, gyms, cafes and other business uses that can change between each other without planning permission, but changing from Class E to residential use is a material change requiring the prior-approval or full planning route.
Sui generis
Uses that do not fit any class, including large HMOs of seven or more unrelated occupants, betting shops and drinking establishments. A change of use to or from a sui generis use normally needs planning permission.
Do I need full planning permission or can I use prior approval?
Some changes of use are permitted development subject to a prior-approval application rather than full planning permission — the best-known example is Class MA, which allows certain Class E commercial premises to become residential (C3) subject to the council assessing specific matters such as flooding, contamination and noise, without a full application. Other changes, including most conversions of a house into self-contained flats, fall outside any prior-approval route and need full householder or full planning permission. We identify which route applies to your building before drawing anything.
| Route | When it applies | Typical package | Fee from |
|---|---|---|---|
| Prior approval (Class MA) | Class E commercial to residential, meeting the criteria | Prior-approval drawings and statement | £1,200 |
| Full planning permission | Conversion into flats, HMO or use outside prior approval | Planning + building regs | £1,600–£2,400 |
| No application needed | Use falls within an existing permitted class change | Drawings for record purposes only | £450 |
