Planning in Bromley — what you need to know
If you are planning a home improvement project in Bromley, understanding the local planning landscape is essential before you begin. Bromley is managed by London Borough of Bromley, which handles all planning applications, enforcement, and local plan policy for the borough.
Largest London borough by area; substantial Green Belt; conservation areas in most town centres; generally permissive elsewhere. The borough has a population of approximately 332,000 residents and covers postcodes BR1, BR2, BR3, BR4, BR5, BR6, BR7, BR8, SE6, SE9, SE12, SE20, SE26.
The housing stock in Bromley is predominantly large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land. This mix of property types means that Bromley Council deals with a wide range of applications, from rear extensions on terraced houses to loft conversions on semi-detached properties and full refurbishments of period homes in conservation areas.
With 48 designated conservation areas and no current Article 4 Directions, Bromley has a planning environment that balances heritage protection in conservation areas with generally permissive policies elsewhere.
At Architectural Drawings London, we prepare planning drawings and building regulations drawings for properties across all Bromley postcodes. Our MCIAT chartered architectural technologists have experience with Bromley Council and understand the specific policies, design guides, and precedents that apply in Bromley. Our fixed fees start from £840 for our Essentials package and £1,750 for our Complete package — 30% below typical London architect rates.
Article 4 Directions in Bromley
Bromley does not currently have any borough-wide Article 4 Directions that restrict Permitted Development rights for standard householder developments such as loft conversions, rear extensions, or outbuildings.
This means that most common home improvements in Bromley can proceed under Permitted Development without needing to apply for planning permission, provided they meet the national criteria for size, height, and position. We recommend applying for a Lawful Development Certificate (£129) to formally confirm that your project qualifies as Permitted Development. This provides legal certainty and is valuable when selling the property.
Even without Article 4 Directions, properties in Bromley's 48 conservation areas have additional restrictions on permitted development. We check the specific restrictions affecting your property as part of our initial assessment.

Bromley has 48 designated conservation areas. Notable conservation areas include:
- Bromley Town
- Chislehurst

In conservation areas, Permitted Development rights are more restricted than in non-designated areas. Key restrictions include:
- No cladding, stone, artificial stone, pebble dash, render, timber, plastic, or tile to any external wall without planning permission
- No side extensions under Permitted Development
- Rear extensions are limited and may require planning permission
- Dormer loft conversions facing the highway require planning permission
- Satellite dishes on front elevations or chimneys are not permitted
- Demolition of gates, walls, fences, or other boundary treatment requires planning permission
If your property is in a Bromley conservation area, we can advise on what is achievable and prepare a planning application that addresses the conservation officer's requirements. Our 98% first-time approval rate includes a strong record in conservation area applications.
Popular projects in Bromley
The types of planning applications most commonly submitted in Bromley are shaped by the borough's housing stock. Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land, which drives demand for specific types of extensions and conversions.
Two-storey extensions
The semi-detached and detached housing stock in Bromley is well suited to two-storey rear extensions, which almost always require planning permission. A two-storey extension can add a larger kitchen-diner at ground floor and an additional bedroom and bathroom above. Bromley Council generally supports two-storey extensions that are subordinate to the original dwelling, set in from the boundary, and do not result in unacceptable loss of light or privacy to neighbours. Our Complete package from £1,750 covers full planning and building regulations drawings.
How much do planning drawings cost in Bromley?
The cost of a planning application in Bromley has two components: the council application fee and the professional drawing fees.

Frequently asked questions
Do I need planning permission in Bromley?

This includes single-storey rear extensions up to 6 metres, most rear dormer loft conversions, and internal alterations. However, if your property is in one of Bromley's 48 conservation areas, PD rights may be restricted and full planning permission may be required. We recommend checking with Bromley Council or applying for a Lawful Development Certificate.
