Changes to permitted development rights for agricultural buildings in 2024
Contents |
[edit] Town and Country Planning Amendment Order 2024
As of May 21, 2024, the Town and Country Planning Amendment Order (General Permitted Development, etc) 2024 comes into effect. This was developed following a consultation undertaken by the Department for Levelling Up, Housing and Communities (DLUHC) in 2023. Prior to this in 2018, the allowable number of homes converted from agricultural buildings into family homes was increased from 3 to 5, and along with other changes, this now increases to 10.
The main changes are outlined here.
[edit] Allowable floorspace increases
The amount of floorspace that can change from agricultural use to ‘flexible commercial use’ will increase from 500 square metres to 1,000 square metres. The amount of floorspace that can change from a building on an agricultural unit and a former agricultural building to a home will increase from 865 square metres to 1,000 square metres.
[edit] Range of commercial building uses widens
The range of uses agricultural buildings and land within their curtilage that can be used for commercial purposes will widen. This will fall under ‘flexible commercial use’ to include:
- the processing of raw goods produced on the site and which are to be sold on the site (excluding livestock)
- the provision of agricultural training
- outdoor sports, recreation and fitness uses within the curtilage of an agricultural building.
[edit] New build and extension areas and volume increases
The ground area limit of new buildings or extensions erected on farms over 5 hectares will be increased in size from 1,000 square metres to 1,500 square metres. For farms under 5 hectares in size the ground area limit for extensions to existing agricultural buildings will increase from 1,000 square metres to 1,250 square metres.
The cubic content limit of an agricultural building will also increase with an extension from 20% to 25% above the original building cubic content.
[edit] Number of allowable homes increases
To encourage conversion of agricultural buildings to homes suited to rural needs, a single maximum floorspace per house is limited to 150 square metres. The number of allowable homes will now be increased to 10, allowing up to 1,000 square metres of floorspace to change use overall. The housing delivered must meet national space standards, and receive prior approval from the local planning authority that they have adequate natural light.
This permitted development right excludes protected landscapes (which includes National Parks and National Landscapes). However the other rights can be used in protected landscapes.
[edit] Restrictions for scheduled monuments
Where there is a designated scheduled monument, extensions and the erection of new buildings is removed. This is to ensure that nationally important monuments are preserved for the benefit of current and future generations.
