Two-storey extension drawings for Newham homes — bedroom above, living space below, drawn against the 3-metre projection and 7-metre boundary rules and to Newham Council's design guidance, 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.
Adding at first floor changes the question the case officer asks. A single-storey extension is judged mostly on daylight and garden loss; a two-storey extension is judged on overlooking, bulk against the neighbouring roofline, and whether it reads as part of the house or bolted onto it. Newham is largely dense Victorian and Edwardian terraces, converted terraced flats and maisonettes and postwar and modern infill housing, and pitched slate roofs on the terraces and front gables on the Edwardian rows set what a matching roof actually means here.
The permitted-development route exists but is narrow: 3 metres of rear projection, a 7-metre stand-off from the rear boundary, eaves and ridge no higher than the original, and side-facing upper windows obscure-glazed and non-opening below 1.7 metres above floor level. Most two-storey schemes fail one of those, usually the 7-metre boundary rule on a shorter garden, and go in as a full application instead. We establish which route applies before designing, because it changes the drawing set.
Conversion and HMO proposals are read against strict amenity, refuse and cycle-storage standards before any consent. 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.
Some two-storey rear extensions are permitted development. You will need a full application to Newham Council if any of these apply:
We set the projection and boundary distance on the site plan, prove the roof-pitch match on the elevations, and specify obscure glazing on the side windows — the three things Newham Council checks first — then submit a validation-complete pack.
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. Two-storey schemes attract more neighbour comment than any other householder work, so the overlooking and daylight case has to be made on the drawings.

Across Forest Gate, East Ham and Plaistow, the schemes that succeed set the first floor back from the ground floor, keep the ridge below the original, and treat the flank wall as blank or obscure-glazed. On dense victorian and edwardian terraces, matching the eaves line matters more than matching the brick: an extension that carries the existing eaves through reads as original even in a different material.
The uniformity of terrace frontages makes front-facing alterations a common refusal reason. We draw the 45-degree daylight test from the neighbour's nearest habitable window, show the window positions in section, and set out the steel and foundation implications early — a two-storey extension changes the load path, so the structural design and the planning design have to be developed together rather than in sequence.
We draw two-storey extensions across Newham. A few of the areas where they come up most often:
Two storey extension drawings for Forest Gate — uniform Victorian terraces of the protected Woodgrange Estate — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
Two storey extension drawings for East Ham — long Edwardian terraces around the conservation area — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
Two storey extension drawings for Plaistow — dense Victorian terraces, much of it converted — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
Two storey extension drawings for Stratford — Victorian stock near the St John's conservation area alongside new development — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
Two storey extension drawings for Manor Park — Edwardian terraces with steady conversion pressure — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
Two storey extension drawings for Upton Park — tightly packed Victorian terraced streets — dimensioned against the 3m and 7m limits and drawn to Newham Council's guidance.
The first-floor limits are tighter than the ground-floor ones. This is how the common cases compare.
| Scheme | Permitted development? | Deciding limit | What Newham Council checks |
|---|---|---|---|
| Two-storey rear, 3m projection, 7m+ to boundary | Often yes | 3m projection / 7m boundary | Roof match, side-window glazing |
| Two-storey rear, under 7m to boundary | No — full application | Rear-boundary distance | Overlooking, daylight, garden loss |
| Two-storey side extension | No — full application | Side elevation | Gap to boundary, street rhythm |
| Two-storey wraparound | No — full application | Combined footprint | Bulk, massing, neighbour amenity |
| Any two-storey on designated land | No — full application | Designation | Character and appearance |

A fixed process built around how Newham Council validates and decides two-storey applications.
Send us your Newham postcode and garden depth. We measure the 7-metre boundary rule against your plot, confirm designation status, and score your odds against live Newham Council decisions.
We measure the original rear wall, eaves and ridge heights, garden depth and every neighbouring window that faces the site — the inputs the daylight and overlooking case is built from.
Chartered designers develop the two-storey addition to your brief with the roof and eaves resolved, and we coordinate the load path so the structural scheme and the planning scheme are the same building.
We submit the application, manage validation and case-officer queries, and revise the drawings free until Newham Council issues its decision.
Often, but not always. A two-storey rear extension can be permitted development if it projects no more than 3 metres, sits at least 7 metres from the rear boundary, does not exceed the existing eaves and ridge, and has obscure-glazed non-opening side windows below 1.7 metres. In Newham, the 7-metre rule is what most commonly forces a full application to Newham Council.
No part of a permitted-development two-storey rear extension may come within 7 metres of the boundary opposite the rear wall of the house. It exists to protect the neighbour behind you from being overlooked at first floor. On shorter Newham gardens this is decisive, and we measure it on survey before any design work rather than discovering it at validation. Newham Council is the decision-maker.
Not under permitted development — two-storey side extensions always need a full application to Newham Council. They are assessed on the gap to the boundary, whether the street's rhythm of spaces between houses survives, and whether the extension is subordinate to the original. Setting the first floor back from the front building line and down from the ridge is what usually makes the difference.
Overlooking is the most common objection, and it is answerable on the drawings. We position habitable-room windows away from neighbouring gardens, obscure-glaze and fix shut anything on the flank below 1.7 metres, and show the sight lines in section. Where the geometry is tight, a rooflight or a high-level window gives the same daylight without the mutual overlooking that draws objections. This applies to your Newham address specifically. Newham Council is the decision-maker.
Almost certainly. Excavating within 3 metres of a neighbouring structure and building on or up to the boundary both trigger the Party Wall etc. Act 1996, and a two-storey extension usually does both. It is entirely separate from Newham Council's planning decision, so we flag the notice period early and detail the junction on the drawings.
Yes. Adding a floor changes the load path from roof to foundation, so beams, padstones and foundation depths all need designing and calculating for building control. Planning and building regulations are separate consents, and the structural set is what building control assesses — we prepare both so the approved scheme is the buildable one. This applies to your Newham address specifically. Newham Council is the decision-maker.
