House Extension Drawings in Gants Hill IG2
Fixed-fee, MCIAT-chartered house extension drawings for Gants Hill (IG2) homeowners — London Borough of Redbridge validation and local constraints handled from the start.
Gants Hill is one of the clearest 1930s suburban grids in IG2 — mile after mile of bay-fronted interwar semis built out in the Metro-land expansion around the gyratory. The consistent plot form makes hip-to-gable lofts, rear dormers and single-storey rear extensions the everyday projects, and the near-identical layouts mean a proven, code-compliant approach can be applied street to street.
Because the great majority of these semis keep their permitted-development rights, much of the work here proceeds on a lawful-development certificate rather than a full householder application. We draw to Redbridge's requirements and the PD volume and set-back rules, using the 45-degree neighbour test to size rear projections so the scheme clears amenity objections cleanly.
Planning in Gants Hill (IG2): what to know before you apply
There is no published householder Article 4 direction across Gants Hill, so the interwar semis generally retain full permitted-development rights for rear extensions, hip-to-gable lofts and dormers, subject to volume and set-back limits. The only nearby heritage designation is the Valentines Mansion parkland setting, so most schemes are governed by amenity and the 45-degree neighbour test rather than conservation control.
Typical Gants Hill housing stock
Gants Hill is textbook 1930s Metro-land Ilford — long avenues of interwar semi-detached houses with bay fronts, hipped roofs and side driveways around the gyratory. This uniform stock is ideal for hip-to-gable loft conversions, rear dormers, single-storey rear extensions and side-infill kitchens.

House Extension Drawings for Gants Hill (IG2) homes: the package and the process
Extension drawings are read for their dimensions. The proposed plan needs depth measured from the original rear wall — not from a previous extension — eaves and ridge heights taken from existing ground level, and the distance to each boundary marked. A site plan showing how much garden remains is what an officer reaches for when the amenity question comes up.
We draw the existing building accurately first, because everything else is measured from it. Where the original footprint has already been added to, that history goes on the drawing: it decides which allowances are still available and it is the first thing an officer checks against the council's own records.
The plot decides the extension type long before taste does. A mid-terrace has depth to work with and an alley if it is lucky; a semi has one clear flank; a detached house can go wide. Reading the building form first is what stops a design being drawn that the plot cannot take.
Which extension types do you draw?
Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.
Rear extension
A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.
Side-return
Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.
Wraparound
Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.
Double-storey
Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.
Basement
Creates space downward where footprint is limited, with structural and party-wall care.
Do I need planning permission for a house extension in London?
Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing. The current depth, height and eaves limits are set out in full in the guide to planning permission for a rear extension, and where you would rather one practice ran the design, the application and the building-regulations stage together, Architectural Drawings covers that full scope.
How do you maximise the footprint the council will approve?
We know each borough's depth, height and daylight standards, so we design to the edge of what will be approved rather than guessing — and we check the 45-degree neighbour daylight rule and any rear building line before submission. Where a plot is tight we test a permitted-development scheme against a slightly larger householder application and show you the trade-off in space, cost and timescale, so the drawn scheme is the one that actually maximises value rather than just floor area.
