New Build Drawings in Mitcham CR4
Fixed-fee, MCIAT-chartered new build drawings for Mitcham (CR4) homeowners — London Borough of Merton validation and local constraints handled from the start.
Mitcham (CR4) wraps around two historic open greens, so extension and loft projects here sit against a genuinely old-London backdrop of Georgian houses, almshouses and the Vestry Hall rather than uniform suburb.
Because the Cricket Green and Lower Green West Conservation Areas plus an April 2023 Article 4 direction overlap much of CR4, we always check the exact boundary before advising permitted development versus a full householder application.
Planning in Mitcham (CR4): what to know before you apply
Homes inside the Cricket Green or Lower Green West Conservation Areas need a full householder application with a heritage justification; those on outer CR4 streets can often use permitted development, subject to a boundary and Article 4 check first.
Typical Mitcham housing stock
A rare surviving cluster of Georgian and early-Victorian houses, almshouses and the Vestry Hall frame Cricket Green and Lower Green, giving way to Victorian terraces and interwar semis on the surrounding CR4 streets.

New Build Drawings for Mitcham (CR4) 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.
