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.

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

At first-floor level the drawings have to answer for daylight, privacy and massing. That means proposed elevations showing every new window with its position relative to the boundary, a section taken through the extension and the neighbouring building, and a roof form drawn to sit below the existing ridge rather than compete with it.

We draw the neighbouring property alongside your own, because the officer's assessment is comparative — the effect on their windows and outlook is the test. Setting the first floor in from the boundary, and showing that set-back as a dimension, resolves most objections before consultation begins.

At first floor the boundary relationship decides everything. A detached house has room to set the addition in on both sides; a semi has one shared wall and one clear flank; a mid-terrace can usually only go to the rear, where the effect on both neighbours has to be drawn.

Do I need planning permission for a double storey extension in London?

Almost always. Permitted development rights for two-storey extensions are far more restrictive than for single-storey work, particularly on how close the new structure can come to a boundary and how closely its roof pitch and eaves height must match the existing house, so most double storey projects are drawn and submitted as full householder planning applications rather than relying on permitted development.

Where the property sits in a conservation area or is subject to an Article 4 direction, any remaining permitted development allowance for a second storey is typically removed entirely, reinforcing the need for a full application. We check your property's status and your borough's design guidance before drawing.

How do councils control the impact of a double storey extension on neighbours?

Because a second storey introduces new windows and massing at first-floor level, London boroughs apply design guidance aimed specifically at protecting neighbouring light, privacy and outlook.

  • The 45-degree rule, tested at neighbouring windows, to check the extension does not block an unreasonable amount of daylight
  • A common design expectation that a two-storey side extension is set in roughly 1 metre from the shared boundary, rather than built hard against it
  • A first floor commonly set back from the ground floor front elevation, so the upper storey reads as subordinate to the main house from the street
  • Obscure or high-level glazing on flank walls facing directly into a neighbour's garden or windows, to limit overlooking

Matching the roofline and materials

Planning officers assess a double storey extension heavily on how convincingly it reads as part of the original house rather than an addition bolted onto the side. Our drawings match ridge height, roof pitch, eaves detail and brick or render finish to the existing building wherever the design brief allows, which is consistently one of the strongest factors in securing approval without delay or redesign. Where a subtly contrasting material is proposed instead — a different brick tone, or a zinc or slate roof against a tiled original — we set it out clearly on the elevations so the design intent reads as deliberate rather than a mismatch, which is how most London boroughs prefer a genuine design statement to be presented.

FAQ

Double Storey Extension Drawings in East Ham E6 — FAQs

How much does a double storey extension cost to design in London?+
Double storey extension drawings start from £2,400, covering full planning permission and structural design for the additional floor. A combined planning and building regulations package with full structural calculations runs up to around £3,850, fixed and agreed upfront.
Do I need planning permission to add a second storey?+
In almost all cases, yes. Permitted development rights for two-storey extensions are much tighter than for single-storey work, particularly around boundary distance and roof matching, so we design double storey projects on the assumption a full householder planning application is required.
Will a double storey extension overlook my neighbour's garden?+
That is exactly what planning officers check, using the 45-degree daylight rule alongside boundary set-in and first-floor set-back guidance. Where a new flank window would look directly into a neighbour's garden, we typically specify obscure or high-level glazing to address it before submission rather than after an objection.
Do I need an architect for a double storey extension?+
No. DrawingsDirect is an MCIAT-chartered architectural technologist practice, producing the same council-accepted drawings and in-house structural coordination as an architect, for a fixed fee typically around 30% lower, with structural calculations for the additional floor produced by the same team rather than a separately appointed engineer.
How long does it take to get double storey extension drawings?+
Drawings are typically ready around 7 days from survey. A householder planning application then has a statutory 8-week determination period once submitted.
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.
