New Build Drawings in West Drayton UB7
Fixed-fee, MCIAT-chartered new build drawings for West Drayton (UB7) homeowners — London Borough of Hillingdon validation and local constraints handled from the start.
West Drayton (UB7) is built around a large open village green fringed by fine Georgian and early-Victorian houses, several of them listed, with a much bigger belt of interwar and postwar suburban housing beyond. Most of the rear and loft extension work we prepare here is on that outer suburban stock, where Hillingdon's standard householder expectations apply.
The West Drayton Green conservation area protects the green and its surrounding listed houses, so on properties facing or near it, frontage changes, materials and rooflines face tighter control. We confirm where a UB7 property sits relative to the conservation-area boundary before recommending a permitted-development or full-application route.
Planning in West Drayton (UB7): what to know before you apply
UB7's split between a listed-building-rich conservation core around The Green and a broad suburban hinterland means the right route depends heavily on location. Away from the green, Hillingdon's residential extension guidance governs; on or beside The Green, listed-building sensitivity and heritage-led design usually point to a full application.
Typical West Drayton housing stock
A historic core around The Green — fine Georgian and early-19th-century houses such as The Old House and Beechwood, with a listed former workhouse cottage row — set within a much larger area of interwar and postwar semis and terraces stretching towards Yiewsley and the railway.

New Build Drawings for West Drayton (UB7) 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.
