Rear Extension Drawings in Tower Hamlets
Fixed-fee, MCIAT-chartered rear extension 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.

Rear Extension Drawings for Tower Hamlets homes: the package and the process
Every rear extension drawings we prepare for a Tower Hamlets property is drawn to London Borough of Tower Hamlets’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A single-storey rear extension is the most common way London homeowners add space, usually taking the form of an open-plan kitchen-diner that opens onto the garden through bi-fold or sliding doors, with rooflights or a roof lantern bringing daylight deep into the plan. Because depth and height are tightly controlled by permitted development rules and by the 45-degree rule that protects neighbouring windows, the design work sits as much in checking what the council will allow as in drawing what you want.
DrawingsDirect draws rear extensions for permitted development, the larger home extension prior-approval scheme and full householder planning, with structural calculations for the opening and roof produced in-house by our MCIAT-chartered team. If your project also involves widening the kitchen sideways or adding a second storey, see our Side Return, Wraparound and Double Storey Extension pages — many London rear extensions grow into one of those during design.
Do I need planning permission for a rear extension in London?
Many single-storey rear extensions qualify as permitted development, meaning no planning application is needed, provided depth, height and materials stay within set limits. That changes if your property sits in a conservation area or is subject to an Article 4 direction, both of which can remove permitted development rights across a street or borough — in that case a full householder planning application is required regardless of size.
Even where an extension qualifies, most homeowners obtain a Lawful Development Certificate to confirm that status in writing before building — useful for mortgage lenders, buyers and Building Control. We check your property against your borough's constraints before recommending a route.
How deep can a single-storey rear extension go?
Depth is the main constraint on a rear extension, and it depends on your house type and whether you use standard permitted development or the larger home extension scheme.
Permitted development
Standard permitted development allows a single-storey rear extension up to 3 metres deep for terraced and semi-detached houses, or 4 metres for detached houses, generally with eaves height limited to match or stay close to the existing house.
Larger home extension scheme
The prior-approval scheme extends this to 6 metres for terraced and semi-detached houses and 8 metres for detached houses. Your council writes to affected neighbours; if none object within the notification period, approval follows without a full planning application. If an objection is raised, the council assesses the impact on neighbouring light and outlook itself, rather than automatically refusing, so a well-considered design still has a good chance of approval.

|---|---|---|
| Permitted development (Lawful Development Certificate) | Depth within 3m (terraced/semi) or 4m (detached), height and materials within PD limits | PD/LDC pack ~£950–£1,450 |
| Larger home extension (prior approval) | Depth up to 6m (terraced/semi) or 8m (detached), with neighbour notification | from £1,100 |
