East Ham (E6) is a district of late-Victorian and Edwardian terraces wrapped around the historic core of St Mary Magdalene church, and its deep rear plots make rear extensions and loft conversions the practical route to more space.

The East Ham Conservation Area plus Newham's borough-wide HMO Article 4 mean we always check whether a property sits inside the designated boundary before recommending permitted development versus a full planning application.

Planning in East Ham (E6): what to know before you apply

Rear and loft schemes on East Ham's terraces are usually achievable under permitted development or a full application, but properties near the East Ham Conservation Area and the listed church face additional heritage scrutiny. Newham's borough-wide Article 4 means any HMO conversion needs planning permission.

Typical East Ham housing stock

E6 is largely late-Victorian and Edwardian terraced housing built out between the 1890s and 1910s, with the historic core around the medieval church of St Mary Magdalene forming the oldest layer of the district.

Rear Extension Drawings for East Ham (E6) homes: the package and the process

Every rear extension drawings we prepare for an East Ham property is drawn to London Borough of Newham’s validation standards and tuned to the E6 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.

FAQ

Rear Extension Drawings in East Ham E6 — FAQs

How much does a rear extension cost to design in London?+
Rear extension drawings start from £1,100, with the final fee set by the route your extension takes — permitted development, prior approval or full planning — and whether you need building regulations and structural calculations bundled in. The fee is fixed and agreed upfront.
Do I need an architect for a rear extension?+
No. DrawingsDirect is an MCIAT-chartered architectural technologist practice, producing the same council-accepted drawings as an architect for a fixed fee typically around 30% lower.
How long does it take to get rear extension drawings?+
Drawings are typically ready around 7 days from survey. Once submitted, councils have a statutory 8-week period to determine a standard householder planning application.
What is the 45-degree rule?+
It is a daylight test many London councils apply to check that a rear extension does not block too much light to a neighbour's nearest window, measured as a line drawn at 45 degrees from that window. We check it before submission, not after a refusal.
Will I need a Party Wall Agreement for a rear extension?+
Only if your foundations or new walls sit on or near the boundary with a neighbouring property. A straightforward rear extension set within your own plot often does not trigger the Party Wall etc. Act 1996, unlike a Side Return or Wraparound extension, which usually does.
Do I need planning permission for a side-return extension in Newham?+
On the Victorian and Edwardian terraces of East Ham, Forest Gate and Plaistow a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always needed. The Woodgrange Estate and other conservation areas restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate where it qualifies.
What is special about building on the Woodgrange Estate?+
The Woodgrange Estate at Forest Gate is a planned Victorian conservation area with a distinctive character the council protects closely — front elevations, boundary walls and rooflines are all controlled. Permitted development is often restricted there, so we design to the estate's character and prepare a full, context-led application where a standard permitted-development route doesn't apply.
What does Newham's borough-wide HMO Article 4 direction affect?+
Newham applies a borough-wide Article 4 direction removing permitted development rights for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application anywhere in the borough. It doesn't affect a standard family extension or loft, but we confirm whether it applies to your intended use before advising.
How long does Newham Council take to decide?+
Newham determines most householder applications within the statutory eight-week period once validated; conservation cases can attract additional consultation. The dense terraced streets are party-wall-sensitive, so the commonest delay is a drawing query — we prepare submissions to the council's householder guidance to keep them moving.
How much do planning drawings cost in Newham?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Newham approves. A side-return, a loft and a Woodgrange Estate application differ in complexity, so we quote once we understand your street and project rather than by the hour.
