Tell us about a site for development
The Local Plan for Buckinghamshire (LP4B) will allocate sites for development in the period up to 2045 to meet the housing, economic and other needs.
We are not currently asking to be informed of potential sites for development.
We're committed to our 'Brown Before Green' pledge and want to ensure new developments are sustainable and make the best use of available land.
In urban planning, a brownfield site is also known as previously developed land (GOV.UK).
Brownfield sites are areas that were previously used for any kind of employment or development, but are now vacant or underused, potentially including industrial or commercial land.
Greenfield sites are sites that have not previously been built on.
Sites submitted in 2021 and 2022
In 2021 we carried out 2 'call for brownfield sites' exercises asking residents to submit previously developed land for consideration.
Following an initial assessment we concluded that not all these sites will be suitable, achievable and available.
Between June and September 2022, we carried out a separate ‘wider call for sites’ exercise.
You can view an interactive map of all submitted sites. We recommend using the Chrome browser to view the map.
For transparency reasons, our list of submitted brownfield sites may also include greenfield sites. After completing the wider call for sites in 2025, we assessed all sites and classified them by their type and suitability for development.
Call for sites 2025
New national policy was introduced in December 2024 that changed the way we calculate our housing needs for Buckinghamshire. We therefore carried out a further call for sites exercise between March and April 2025 as the Local Plan now needs to provide sites for approximately 91,000 new homes for the period until 2045, an increase of about 30,000 homes and equivalent to an annual increase from 2,912 to 4,319.
Call for gypsy and traveller sites
The Local Plan for Buckinghamshire (LP4B) will allocate sites for development in the period up to 2045 to meet the housing, economic development need including the Gypsy, Traveller and Travelling Show people needs of Buckinghamshire.
A targeted Gypsy and Traveller call for sites took place between 17 September – 29 October 2025. The promoted sites will be assessed on their suitability, availability and achievability and the outcomes of these assessments will be published in due course.
How we assess the sites
We technically assess all sites submitted against our Housing and Economic Land Availability Assessments (HELAA) methodology.
The assessment determines how well a site can accommodate development. We will assess sites for their:
- suitability
- availability
- achievability (including viability) to accommodate development
To show you how the process works we've published the methodology on the HELAA webpage.
Further information is available at Housing and Economic Land Availability Assessments (HELAA) (GOV.UK).
