House Extension Drawings in Addiscombe CR0
Fixed-fee, MCIAT-chartered house extension drawings for Addiscombe (CR0) homeowners — Croydon Council validation and local constraints handled from the start.
Addiscombe in CR0 sits just east of central Croydon and blends Victorian and Edwardian terraces with interwar semis on generous suburban plots. It is very much a family-extension neighbourhood, so most of our work is rear and side extensions, loft conversions and garage conversions that add practical space for growing households.
Away from the East India Estate conservation area, much of Addiscombe is comparatively permitted-development friendly, which can open up straightforward routes to more space. Where conservation control or a larger scheme applies, we prepare full planning drawings that address Croydon's amenity, scale and materials tests so the application is assessed on solid ground.
Planning in Addiscombe (CR0): what to know before you apply
There is no published householder Article 4 direction we depend on for Addiscombe, and much of the suburb benefits from permitted-development rights for modest extensions and lofts. The main exception is the East India Estate conservation area, where frontage, roof and material changes are more tightly controlled; elsewhere neighbour amenity and extension depth are the key limits.
Typical Addiscombe housing stock
Addiscombe, east of central Croydon, mixes Victorian and Edwardian bay-fronted terraces with interwar semi-detached housing along its residential streets. It is a strong family-extension market, so the common projects are rear and side extensions, loft conversions and garage-to-room conversions that add space without the tight constraints of inner London.

House Extension Drawings for Addiscombe (CR0) 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.
