Double Storey Extension Drawings in Kidbrooke SE3
Fixed-fee, MCIAT-chartered double storey extension drawings for Kidbrooke (SE3) homeowners — Royal Borough of Greenwich validation and local constraints handled from the start.
Kidbrooke (SE3) is a district defined by change: the system-built Ferrier Estate has been cleared and rebuilt as Kidbrooke Village, one of the largest housing regeneration schemes in south-east London, ringed by surviving interwar and postwar suburban housing. Householder extension and loft work concentrates on those older semi-detached and terraced houses on the fringes, where drawings have to respond to a genuinely mixed streetscape.
There is no conservation area covering Kidbrooke — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the scale of the ongoing regeneration and by the varied older housing around it, read against the Royal Borough of Greenwich's householder design expectations. We treat the immediate context of each house, rather than a conservation designation, as the reference point when we design an extension.
Across streets like Westbrook Road, Dursley Road and Whetstone Road, demand is steady for rear extensions, side infills and loft conversions on the interwar and postwar houses. We check each property's permitted-development position against Greenwich's borough-wide controls — and, on newer Kidbrooke Village homes, any developer conditions or covenants — before preparing drawings that either stay within permitted development or are ready to validate as a full householder application.
Planning in Kidbrooke (SE3): what to know before you apply
Greenwich assesses Kidbrooke extensions against the immediate context, which varies from new-build village blocks to older interwar and postwar houses, so the design has to respond to each house rather than a single estate pattern. There is no conservation area and no local Article 4 direction, so many older houses retain permitted development rights for rear and loft work — but on newer homes, developer conditions and covenants can restrict alterations, and neighbour amenity and building lines remain the points a householder application is judged on.
Typical Kidbrooke housing stock
A rapidly changing mix of new-build Kidbrooke Village apartments and houses alongside surviving interwar and postwar semi-detached and terraced homes on the fringes. The suburban houses around the regeneration area are where most householder extension and loft work happens.

Double Storey Extension Drawings for Kidbrooke (SE3) 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.
