House Extension Drawings in Camberwell SE5
Fixed-fee, MCIAT-chartered house extension drawings for Camberwell (SE5) homeowners — London Borough of Southwark validation and local constraints handled from the start.
Camberwell (SE5) in Southwark ranges from the grand Georgian villas of Camberwell Grove — one of inner south London's finest early-19th-century streets — to the tighter Victorian terraces around Camberwell Green and Church Street. That mix means the right route for a loft or extension depends heavily on which part of SE5 a house sits in.
Two conservation areas, Camberwell Grove and Camberwell Green, cover much of the neighbourhood and closely control rooflines, materials and front elevations, while Southwark's Article 4 directions here mainly govern the town centre and shopping frontages rather than householder work. We check a Camberwell address against both before recommending a permitted-development or full-application route.
Planning in Camberwell (SE5): what to know before you apply
Southwark's Article 4 directions in SE5 largely concern Camberwell town centre and its protected shopping frontages rather than householder projects, so many Camberwell houses keep permitted development rights — but the Camberwell Grove and Camberwell Green conservation areas are the significant exceptions, tightly controlling the Georgian and Victorian rooflines and elevations that give the area its character.
Typical Camberwell housing stock
Grand Georgian and early-Victorian villas along Camberwell Grove and Grove Lane, denser Victorian terraces toward Camberwell Green and Church Street, and Georgian and Victorian houses climbing Denmark Hill.

House Extension Drawings for Camberwell (SE5) 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.
