Annexe and granny-flat drawings for Newham homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Newham Council's policies, delivered in days and revised free until your decision.
Newham Council granted 86% of the householder planning decisions it made in its latest published year — 1 point below the 87% England-wide householder average. Conversion and HMO proposals are read against strict amenity, refuse and cycle-storage standards before any consent, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910) 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. Newham carries at least one Article 4 direction, and conservation areas including Woodgrange Estate, St John's (Stratford) and East Ham remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Newham is determined against an 8-week statutory target.
Forest Gate (uniform Victorian terraces of the protected Woodgrange Estate), East Ham (long Edwardian terraces around the conservation area), Plaistow (dense Victorian terraces, much of it converted), Stratford (Victorian stock near the St John's conservation area alongside new development), Manor Park (Edwardian terraces with steady conversion pressure) and Upton Park (tightly packed Victorian terraced streets) — these are the Newham pockets our drawings cover most. Heritage designations here include Woodgrange Estate, St John's (Stratford), East Ham, Plaistow and Manor Park. Newham Council weighs each proposal against Newham Local Plan and the borough's supplementary guidance on residential extensions and conversions, where the uniformity of terrace frontages makes front-facing alterations a common refusal reason. A very large proportion of Newham's terraces have been split into flats and HMOs, so permitted-development rights rarely apply and conversion quality is closely policed.. On roofs the borough is pitched slate roofs on the terraces and front gables on the Edwardian rows, over dense Victorian and Edwardian terraces, converted terraced flats and maisonettes and postwar and modern infill housing.
Councils do not decide annexes on square metres. They decide whether, once built, the accommodation forms part of one planning unit with the main house or a second one beside it. Newham Council looks at whether the garden is shared or divided, whether the annexe has its own street access and address, whether the occupier could live there entirely independently, and whether the two households would function as one. That is the whole case, and it is made or lost on the layout.
Newham is largely dense Victorian and Edwardian terraces, converted terraced flats and maisonettes and postwar and modern infill housing, which shapes the realistic options: converting part of the existing house, extending it, or building a detached unit in the garden. A detached annexe can sometimes sit under Class E as an outbuilding incidental to the enjoyment of the dwellinghouse — but sleeping accommodation is generally not "incidental", so a garden annexe with a bedroom usually needs its own permission rather than relying on outbuilding rights.
In Newham's conservation areas — including Woodgrange Estate and St John's (Stratford) — a garden building is also judged on its effect on the character of the area, which limits height and footprint before the use question is reached. The Woodgrange Estate conservation area in Forest Gate carries an Article 4 direction protecting its uniform Victorian frontages, and Newham also operates directions tied to its licensing of houses in multiple occupation.
An annexe almost always needs an application to Newham Council. Expect one where any of these apply:
We plan the annexe so its relationship to the main house is visible on the page — shared garden, connected access, a layout that reads as one household — and set out the case Newham Council has to test, rather than leaving the officer to assume the worst.
Below is Newham Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Newham approves a fair majority of householder applications, with the intense conversion and HMO pressure on its terraced streets the dominant constraint on new schemes. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Forest Gate, East Ham and Plaistow, the annexes that succeed keep one shared garden, take access past the main house rather than from the street, and are modest against the host building — single storey where the plot is overlooked, and set back from boundaries. On dense victorian and edwardian terraces, converting an integral garage or a rear ground floor is often approved more readily than a detached garden unit, because the ancillary relationship is self-evident.
Conversion and HMO proposals are read against strict amenity, refuse and cycle-storage standards before any consent. Where Newham Council grants permission, it commonly attaches a condition tying occupation of the annexe to the main dwelling. That condition is not a problem to be avoided — it is usually the mechanism that makes approval possible, and we draft the application on that basis rather than pretending the annexe is something it is not.
We draw annexes across Newham. A few of the areas where multigenerational schemes come up most often:
Annexe and granny-flat drawings for Forest Gate — uniform Victorian terraces of the protected Woodgrange Estate — planned to stay ancillary and drawn to Newham Council's policies.
Annexe and granny-flat drawings for East Ham — long Edwardian terraces around the conservation area — planned to stay ancillary and drawn to Newham Council's policies.
Annexe and granny-flat drawings for Plaistow — dense Victorian terraces, much of it converted — planned to stay ancillary and drawn to Newham Council's policies.
Annexe and granny-flat drawings for Stratford — Victorian stock near the St John's conservation area alongside new development — planned to stay ancillary and drawn to Newham Council's policies.
Annexe and granny-flat drawings for Manor Park — Edwardian terraces with steady conversion pressure — planned to stay ancillary and drawn to Newham Council's policies.

Three similar buildings, three different consents. This is what separates them.
| What you build | Planning status | Key test | What Newham Council checks |
|---|---|---|---|
| Garden room, no sleeping space | Often Class E permitted development | Incidental to the house | Height, footprint, boundary position |
| Annexe used by the household | Full application, usually with a tie condition | Ancillary use | Shared garden and access, layout |
| Self-contained unit, own access | New dwelling — full application | Separate planning unit | Policy on new homes, amenity, parking |
| Converted garage or ground floor | Often permitted, use still assessed | Whether use changes | Independence of the accommodation |
| Annexe on designated land | Full application | Designation | Character and appearance |
The ancillary/separate-dwelling distinction comes from section 55 of the Town and Country Planning Act 1990; outbuilding limits from the GPDO 2015, Schedule 2, Part 1, Class E.
A fixed process built around how Newham Council tests the use question as well as the design.
Tell us who the annexe is for and where it would sit on the plot. We confirm designation status and tell you honestly whether the scheme reads as ancillary or as a separate dwelling in Newham.
We measure the plot, the existing house and the access route, so the shared-garden and shared-access case can be drawn rather than asserted.
Chartered designers develop the annexe to your brief, with the layout, access and garden relationship arranged to support the ancillary case under Newham Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Newham Council decides.
Almost always. Sleeping accommodation is generally not "incidental" to the enjoyment of a house, so it falls outside the outbuilding permitted-development right, and any annexe that could function independently raises a change-of-use question under section 55. In Newham we prepare a full application to Newham Council and make the ancillary case explicitly rather than hoping it is not asked.
A shared garden rather than a divided one, access through the main property rather than a separate street entrance, occupation by a member of the same household, and a physical and functional relationship with the main house. Newham Council weighs those together — no single feature decides it, but a separate front door and a fenced-off garden together usually settle it against you.
Yes, subject to permission. A detached garden annexe is assessed on its scale against the plot, its effect on neighbours and the character of the area, and then on the use question. Keeping it single storey, set in from boundaries and served off the shared garden gives it the best prospect in Newham, particularly near designated areas such as Woodgrange Estate and St John's (Stratford). Newham Council is the decision-maker.
Commonly, yes — a condition tying occupation of the annexe to the main dwelling, so it cannot be sold or let separately. That is normally what makes approval possible, because it removes the concern that a new independent home is being created without going through housing policy. The condition runs with the land, so it matters at resale, and we explain the implications before you commit. This applies to your Newham address specifically. Newham Council is the decision-maker.
Yes. A new annexe is new habitable accommodation, so structure, fire escape, insulation and ventilation all apply, and a detached annexe close to a boundary raises fire-spread requirements as well. Planning and building control are separate consents with separate submissions — we prepare both so the approved design is the one that can actually be built. This applies to your Newham address specifically. Newham Council is the decision-maker.
A householder application runs to an eight-week statutory target; where the council treats the annexe as creating a new unit it becomes a minor application with a thirteen-week target instead. Which route applies depends on how the use is characterised, which is precisely why the ancillary case is worth making properly at the outset. This applies to your Newham address specifically. Newham Council is the decision-maker.
