Beddington (CR0) centres on a historic village core — Carew Manor and Beddington Park with its medieval church — that was surrounded by interwar suburban housing as south London expanded. Importantly, it lies within the London Borough of Sutton despite sharing the CR0 postcode with Croydon, so householder work here is governed by Sutton's controls. Most projects are extensions or lofts on the interwar semi-detached and terraced houses that ring the old village.

There is no conservation area covering the Beddington part of CR0 — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the contrast between the historic village nucleus and the surrounding interwar suburban streets, and by the London Borough of Sutton's householder design expectations, which lean on keeping original building lines, materials and roof forms intact. We treat that layered character, rather than a conservation designation, as the reference point when we design an extension.

Demand for rear extensions, side infills and loft conversions runs steadily across roads like Queenswood Avenue, Royston Avenue and Rookwood Avenue, where interwar houses sit on regular planned plots. We check each property's permitted-development position against Sutton's borough-wide controls first — and, for homes toward the Wandle, any surface-water drainage implications — then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.

Planning in Beddington (CR0): what to know before you apply

Beddington sits within the London Borough of Sutton despite its CR0 postcode, so householder applications are validated and assessed by Sutton against the prevailing character of the interwar streets that ring the historic village. There is no conservation area and no local Article 4 direction in the Beddington part of CR0, so many houses retain permitted development rights for rear and loft work — but modest interwar plots, shared building lines and low-lying ground toward the Wandle mean depth, height, neighbour impact and drainage are the points a scheme is judged on.

Typical Beddington housing stock

A historic village nucleus surrounded by predominantly interwar semi-detached and terraced houses, with postwar and modern infill toward the Wandle. It is this interwar suburban ring, on regular planned plots, that drives most of the rear-extension, side-infill and loft-conversion work across the area.

House Extension Drawings for Beddington (CR0) homes: the package and the process

Every house extension drawings we prepare for an Beddington property is drawn to London Borough of Sutton’s validation standards and tuned to the CR0 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.

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.

FAQ

House Extension Drawings in Beddington CR0 — FAQs

How far can I extend without planning permission in London?+
Under permitted development, single-storey rear extensions can reach 3m (terraced/semi) or 4m (detached), or up to 6–8m under the prior-approval larger-home scheme — but conservation areas and Article 4 directions can remove these rights. We check your property first.
Do extension drawings include structural calculations?+
Our full package includes structural drawings and calculations coordinated in-house, so your builder can price and build without waiting on an engineer.
How long do extension drawings take?+
Typically about 7 days from survey to a full drawing set delivered to your online portal.
Will my rear extension need a party wall agreement?+
If you build up to or on a shared boundary, excavate near a neighbour's foundations, or cut into a party wall for a steel, the Party Wall etc. Act 1996 usually applies. Our drawings show the works clearly so a party wall surveyor — or your neighbour — can see exactly what is proposed, which keeps that process quick.
Can I extend a house in a conservation area?+
Yes, but conservation areas and Article 4 directions commonly remove permitted development for rear and side extensions, so the work needs a full householder application designed to the council's heritage guidance. We confirm your property's designation before recommending a route.
Do I need planning permission to extend a house in Beddington?+
Not always. Many Beddington houses retain permitted development rights, so a modest single-storey rear extension or a rear loft conversion can often proceed without a full planning application. Because Beddington sits in the London Borough of Sutton and the interwar plots are fairly modest, we check your property's size limits and building lines against Sutton's controls first — and any drainage points for homes toward the Wandle — and prepare a full householder application where the project goes beyond permitted development.
Is Beddington in a conservation area?+
No. There is no conservation area covering the Beddington part of CR0. Its planning character is shaped instead by the contrast between the historic village core and the surrounding interwar suburban streets, together with Sutton's householder design expectations, which favour keeping original building lines, materials and roof forms intact when you extend.
How much do planning and building-regulation drawings cost for a Beddington extension?+
We work to fixed fees agreed before we start, with a typical turnaround of around seven days for a standard rear extension or loft on a Beddington house. As a chartered architectural technologist practice we produce the same council-accepted planning and building-regulation drawings as an architect, usually for a lower fee, and include free redraws until your application is approved.
