Double Storey Extension Drawings in Bethnal Green E2
Fixed-fee, MCIAT-chartered double storey extension drawings for Bethnal Green (E2) homeowners — London Borough of Tower Hamlets validation and local constraints handled from the start.
Bethnal Green (E2) in Tower Hamlets carries three conservation areas of quite different kinds: the Jesus Hospital Estate around Columbia Road, a planned Victorian estate; Hackney Road, protecting historic frontages along the northern edge; and Regents Canal, covering the waterway setting.
The Jesus Hospital Estate is the one that most often reshapes a scheme. Because it was laid out as a single planned estate of uniform terraces, the designation exists to protect that uniformity, so elevation and roof changes are judged against the original pattern rather than assessed in isolation. Along the canal, the Regents Canal conservation area means rear elevations and roof alterations visible from the towpath are considered for their contribution to that view. The Cambridge Heath 1 Article 4 direction removes permitted development rights in the area it covers. We check which designation and direction apply to an E2 address before drawing to Tower Hamlets' guidance.
Planning in Bethnal Green (E2): what to know before you apply
E2 is covered in part by the Cambridge Heath 1 Article 4 direction, removing permitted development rights where it applies. Three conservation areas shape the rest: the Jesus Hospital Estate, a planned Victorian estate where uniformity is the designated character and elevation changes are judged against the original pattern; Regents Canal, controlling rear elevations and rooflines visible from the towpath; and Hackney Road, protecting the historic frontages along the northern edge.
Typical Bethnal Green housing stock
Victorian terraces including the planned Jesus Hospital Estate around Columbia Road, with canal-side former industrial buildings and substantial post-war estates between the historic streets.

Double Storey Extension Drawings for Bethnal Green (E2) 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.
