House Extension Drawings in Thames View IG11
Fixed-fee, MCIAT-chartered house extension drawings for Thames View (IG11) homeowners — London Borough of Barking and Dagenham validation and local constraints handled from the start.
Thames View (IG11) is a cohesive 1950s London County Council overspill estate, built on former marshland south of Barking town centre as a planned postwar community of low-rise council-built houses and blocks. That open, uniform estate layout — quite distinct from the borough's older terraced streets — is what shapes nearly every householder project here, so an extension has to sit comfortably within a very consistent, planned streetscape.
There is no conservation area covering Thames View — that is a genuine, verified fact, not an omission. Its planning character is shaped instead by the sheer uniformity of the estate layout and by Barking and Dagenham's householder design expectations, which lean on keeping the original postwar rhythm, materials and building lines intact. We treat that estate cohesion, rather than a conservation designation, as the reference point when we design an extension.
Because so many Thames View houses passed into private ownership after Right to Buy, demand for rear extensions, side infills and loft conversions is steady across streets like Bastable Avenue, Maplestead Road and Moore Crescent. We check each property's permitted-development position against Barking and Dagenham's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.
Planning in Thames View (IG11): what to know before you apply
Because the estate is so uniform, Barking and Dagenham assess extensions on Thames View houses against the consistent postwar street pattern, so matching brick, render and roof form matters more than on a mixed-typology road. There is no conservation area and no estate-specific Article 4 direction, so many houses retain permitted development rights for rear and loft work — but the open estate layout, shared building lines and low-lying former-marshland ground mean spacing, neighbour impact and drainage are the points an application turns on.
Typical Thames View housing stock
Cohesive 1950s council-built houses and low-rise blocks arranged on a planned, open postwar layout, many now privately owned following Right to Buy — which is what drives the steady flow of rear-extension and loft-conversion work across the estate.

House Extension Drawings for Thames View (IG11) 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.
