Double Storey Extension Drawings in Homerton E9
Fixed-fee, MCIAT-chartered double storey extension drawings for Homerton (E9) homeowners — London Borough of Hackney validation and local constraints handled from the start.
Homerton (E9) in Hackney is shaped by Victoria Park along its southern edge. The Victoria Park conservation area covers the villas and terraces facing the park — Victoria Park Road and Cassland Road among them — and the park-edge townscape is the designated character, which means alterations visible from the park are assessed on their contribution to it.
The Well Street conservation area protects the historic frontages around the older centre to the north, while the middle of the district is largely post-war estate. The mature tree cover along the park edge makes tree protection a routine consideration on rear and roof projects there, and it is worth establishing early because it affects where an extension can physically go. We check the conservation-area boundaries and the tree position for an E9 address before drawing to Hackney's residential guidance.
Planning in Homerton (E9): what to know before you apply
E9 has no householder Article 4 direction, so many Homerton houses retain permitted development rights for rear and loft work — but the Victoria Park conservation area covers the villas and terraces facing the park, where the park-edge townscape is the designated character and alterations visible from it are assessed accordingly, and the Well Street conservation area protects the older centre. Mature trees along the park edge are a routine constraint on rear and roof schemes.
Typical Homerton housing stock

Double Storey Extension Drawings for Homerton (E9) 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.
