Planning Drawings in Bromley
Fixed-fee, MCIAT-chartered planning 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.

Planning Drawings for Bromley homes: the package and the process
A planning set is judged as a set, not as individual sheets. Every existing drawing needs its proposed counterpart at the same scale and orientation so the officer can read the change at a glance, each sheet needs its own number, title, scale bar and north point, and the whole package needs to survive being printed at A3 without a dimension becoming illegible.
We draw to the conventions validation teams expect: plans and elevations at 1:100 or 1:50, a location plan at 1:1250 with the site edged red, a block plan at 1:500, and sections cut where the change in level or roof form actually happens rather than where they are easiest to draw.
The drawing list itself changes with the building. A detached house needs four elevations; a mid-terrace needs two plus a section through the party walls to show what is not visible from outside. Getting that list right at the start is what stops a validation officer asking for a sheet three weeks in.
What is included in a planning drawing set?
A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.
- Site location plan (1:1250) and block plan (1:500)
- Existing floor plans, elevations and sections
- Proposed floor plans, elevations and sections
- Roof plans where relevant, with heights and materials annotated
- A design and access or heritage statement where the borough requires one
How are planning drawings different from building regulations drawings?
Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.
How quickly can you produce planning drawings in London?
After a laser survey, a standard householder set is typically ready within 7 days. We review every drawing against your borough's validation checklist before it reaches a planner's desk, which is why our first-time approval rate sits around 96%.
| Drawing | Typical scale | What it shows |
|---|---|---|
| Site location plan | 1:1250 | The property in its street context, site edged red |
| Block plan | 1:500 | The building's footprint and position in the plot |
| Floor plans (existing & proposed) | 1:100 / 1:50 | Room layout, walls, openings and the proposed changes |
| Elevations (existing & proposed) | 1:100 / 1:50 | Each face of the building and how it changes |
| Sections | 1:100 / 1:50 | A cut through showing heights, levels and roof form |
