New Build Drawings in Willesden NW10
Fixed-fee, MCIAT-chartered new build drawings for Willesden (NW10) homeowners — London Borough of Brent validation and local constraints handled from the start.
Willesden (NW10) in Brent is a densely built late-Victorian and Edwardian neighbourhood centred on Willesden High Road and Walm Lane, where rear and loft projects on the terraces and bay-fronted houses are the everyday work. The Willesden Green conservation area — extended in 2024 — now reaches beyond the High Road parades to take in Brondesbury Park, Rutland Park Mansions and the Chatsworth Road and Dean Road streets.
Two conservation areas shape the district: Willesden Green in the centre and Kensal Rise to the south around Chamberlayne Road. Brent also runs an Article 4 direction on converting houses to small HMOs, so we confirm whether a Willesden address sits inside a conservation-area boundary — and whether a scheme is a householder extension or a change of use — before recommending a permitted-development or full-application route.
Planning in Willesden (NW10): what to know before you apply
Willesden houses generally retain permitted development rights for rear and loft work, but the Willesden Green and Kensal Rise conservation areas control frontages and rooflines across much of NW10, and Brent's Article 4 direction removes the right to convert a house to a small HMO without permission. We check the conservation-area boundary and the proposed use first, then draw to Brent's residential extensions guidance.
Typical Willesden housing stock
Late-Victorian and Edwardian terraces and bay-fronted houses on the streets around Willesden High Road and Walm Lane, with mansion blocks along the main roads and pockets of interwar and post-war infill toward Harlesden and Kensal.

New Build Drawings for Willesden (NW10) 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.
