New Build Drawings in Sanderstead CR2
Fixed-fee, MCIAT-chartered new build drawings for Sanderstead (CR2) homeowners — Croydon Council validation and local constraints handled from the start.
Sanderstead (CR2) sits high on the chalk of the North Downs and developed as a 1920s–1930s suburb after the railway arrived in 1884. Its housing is predominantly interwar detached and semi-detached houses on elevated, leafy roads rather than a dense urban grain, so most householder projects here are extensions or lofts that need to sit comfortably within spacious, green streets.
There is no conservation area covering the Sanderstead part of CR2 — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the consistency of the interwar suburban layout, the generous plots and setbacks, and the London Borough of Croydon's householder design expectations, which lean on keeping the spacing between houses, original materials and roof forms intact. We treat that suburban character, rather than a conservation designation, as the reference point when we design an extension.
Demand for rear extensions, side extensions and loft conversions runs steadily across roads like Mitchley Hill, Arundel Avenue and The Ridge Way, where detached and semi-detached houses sit on generous, sloping plots. We check each property's permitted-development position against Croydon'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 Sanderstead (CR2): what to know before you apply
Because Sanderstead is a consistent interwar suburb of detached and semi-detached houses, Croydon assess extensions against the spacing, setbacks and green character of the street, so preserving gaps between houses and matching original materials and roof form matters alongside the numbers. There is no conservation area and no local Article 4 direction in the Sanderstead part of CR2, so many houses retain permitted development rights for rear and loft work — but generous-but-finite plots, mature gardens and the sloping topography mean depth, height and neighbour impact are the points a householder application is judged on.
Typical Sanderstead housing stock
Predominantly interwar detached and semi-detached houses on spacious, elevated plots, with mature gardens and some postwar and modern infill. Those generous plots and leafy setbacks are what shape most of the rear-extension, side-extension and loft-conversion work across the area.

New Build Drawings for Sanderstead (CR2) homes: the package and the process
A new dwelling is a full application rather than a householder one, and the drawing set reflects that: site layout with levels and boundaries, floor plans and elevations for the new building, sections showing how it sits in the ground, and street-scene elevations placing it against what is already there.
Two packages follow the approval — the planning set and the construction set — and they have to stay in step. Foundation design, drainage strategy, thermal performance and fire strategy are drawn for Building Control against the same geometry that was granted permission, so the built house matches the approved one.
An infill plot is designed against its neighbours. Plot width, the building line either side, and the ridge heights next door set what the new house can be — and on a tight urban site those constraints usually shape the design more than the brief does.
Is my plot suitable for a new build in London?
A feasibility assessment looks at plot size and shape, access, existing boundary conditions, relevant planning policy for the borough, and the likely impact of a new dwelling on neighbouring properties before any design work begins. Infill plots — a gap between existing buildings on a street — and backland plots — a garden or yard site behind existing houses, reached by a shared access — each raise different issues: infill schemes are usually judged on how well they match the scale, spacing and character of the street, while backland schemes are judged heavily on overlooking, garden loss for neighbours, and whether the access arrangement is acceptable. A feasibility study gives an honest view of whether a scheme is likely to succeed before you commit to full drawings.
What does pre-application advice add to a new build project?
Pre-application advice is a formal, paid process most London boroughs offer, where planning officers give written feedback on a proposed scheme before a full application is submitted. For a new build — where the principle of development itself is often the main issue, not just the design details — this feedback can be invaluable: it surfaces concerns around density, massing, daylight and sunlight or heritage context early enough to be addressed in the drawings, rather than discovered for the first time as a refusal reason months into a full application. We prepare and submit pre-application enquiries as part of the new build service where it is likely to strengthen the eventual planning application.
How do daylight, sunlight and overlooking affect a new build design?
London boroughs assess new dwellings against their effect on the daylight and sunlight reaching neighbouring homes and gardens, commonly using the 45-degree rule as an initial check on a proposal's massing and position relative to neighbouring windows, alongside more detailed daylight and sunlight assessment on sensitive sites. Overlooking and loss of privacy from new windows, upper floors or roof terraces are assessed similarly, and often shape decisions on window placement, floor-to-floor heights and the overall footprint and massing of the new building. Designing with these constraints from the earliest sketch stage, rather than adjusting for them after a refusal, is one of the main advantages of instructing feasibility and pre-application work before a full planning set.
