New Build Drawings in Bromley
Fixed-fee, MCIAT-chartered new build drawings for Bromley homeowners — London Borough of Bromley validation and local constraints handled from the start.
As London's largest borough by area, Bromley offers the generous interwar detached and semi-detached plots that make substantial rear and double-storey extensions genuinely viable. The housing stock runs from suburban semis around Beckenham, Penge and West Wickham to larger detached homes and edge-of-London properties toward Orpington, Hayes and Chislehurst. The right Bromley application is usually about maximising a large plot within policy rather than squeezing a tight terrace, and the room to build is exactly why so many owners here extend rather than move.
Two constraints shape what is achievable. Green-belt designation across the borough's outer edges restricts the scale of additions on properties toward Orpington and Chislehurst, where extensions are assessed against strict limits on disproportionate additions to the original dwelling. Conservation control in Chislehurst, Keston, Hayes, Park Langley and Bromley Town governs materials and design in those areas. Bromley has no borough-wide Article 4 direction affecting typical householder permitted development, so detached homes here often retain fuller rights than inner-London terraces, which we always check first.
We prepare Bromley planning drawings that use the available plot fully while respecting green-belt and conservation constraints, confirming permitted development limits for detached and semi-detached homes before we draw and evidencing green-belt cases carefully where they apply. Because the plots allow larger schemes, we design to the project rather than a standard template, and we agree a fixed fee up front, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Bromley approves. The council determines most householder applications within the statutory eight-week period once validated, so a complete, correctly scaled, validation-first submission is the best way to hold that timescale.


Planning in Bromley: what to know before you apply
Bromley has no borough-wide Article 4 direction affecting typical householder permitted development; the binding constraints are green-belt policy on outer properties and conservation-area control in Chislehurst, Keston and Bromley Town. Detached homes here often retain fuller permitted development rights than inner-London terraces.
Typical Bromley housing stock
Large interwar detached and semi-detached houses with generous plots, plus green-belt and edge-of-London properties toward Orpington and Chislehurst.

What the numbers say about Bromley planning decisions
These are London Borough of Bromley’s own reported figures, published by government rather than estimated by us. They are what we design against — a borough that refuses one householder application in five needs a different drawing package from one that refuses one in twenty.

New Build Drawings for Bromley 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.
