However, in England and Wales, the [http://www.legislation.gov.uk/uksi/1995/418/contents/made Town and Country Planning (General Permitted Development) Order 1995] enabled central government to permit certain types of developments known as permitted developments. These were generally minor changes to existing properties. Permitted developments do not require approval from the local planning authority as permission is granted by the Order.

The changes brought about by the new order aimed to streamline and expand permitted development rights in specific areas, in particular agricultural buildings, simplifying the process of converting and developing properties without the need for full planning permission.

		+
		+	On 4 February 2025 the [https://researchbriefings.files.parliament.uk/documents/LLN-2025-0011/LLN-2025-0011.pdf Permitted Development Rights (Extension) Bil]l, a private member’s bill tabled by Lord Lucas (Conservative) was published. The Permitted Development Rights (Extension) Bill [HL] would establish new PDRs in primary legislation in England and Wales, they are currently made available through secondary legislation.
		+
		+	The PDRs proposed in the bill are listed in its schedule and would apply to developments including; making changes to the height of the roof of a building, adding side and rear extensions, raising party walls, adding floors to a bungalow, increasing the height of buildings in town centres by up to four stories, installing air source heat pumps, solar panels and electric vehicle charging points.
		+
		+	The schedule also sets out criteria that developments should meet in order to qualify for the new PDRs created by the bill. For example, the bill states the ridge height and eaves of a building may only be raised by up to one metre in order for the development to qualify. Other specifications include limits to the size of side or rear extensions to a property and to the maximum height that solar panels placed on top of a building may rise above the roof. Developments would also need to meet general restrictions set out in the bill: That developments must not erase a right of way or an easement, infringe on the right to light, substantially reduce the light available to existing solar panels or infringe on other private rights unless this is agreed with the other parties concerned. It also states PDRs would not apply to listed buildings.
		+
		+	The bill would enable a planning authority to impose design requirements in relation to PDRs (though these may not have the effect of making a development “unreasonably impracticable or uneconomic”) and assigns them powers to impose:
		+
		+	* measures to slow the run-off of rainwater from the property being developed
		+	* requirements concerning the building’s structural safety
		+	* standards for insulation or energy efficiency
		+	* requirements for new roof areas created as part of the development, such as a requirement to install a ‘green roof’ (a roof partially or completely covered by vegetation)
		+
		+	The specific requirements that would be applied would be established by the secretary of state using delegated powers in the bill. The planning authority would also be given the power to impose charges to cover the cost of providing additional infrastructure if the development increased the number of rooms in a property beyond a limit set out in secondary legislation.
		+
		+	The bill includes a further restriction on the application of the new PDRs for the development of residential buildings in medium and high flood risk areas (flood risk vulnerability classifications 2 and 3). Properties in these areas would need to be “well served by public transport” (the definition of which would be set out in secondary legislation) and modified to be flood resilient in order to qualify for PDRs.

Prior to this in 2018, the allowable number of homes converted from agricultural building sinto family homes was increased from 3 to 5, and along with other changes, this now increases to 10.
		+
		+	The main changes were:
		+
		+	* Allowable floorspace: The floorspace that can change from agricultural use to ‘flexible commercial use’ increased from 500 square metres to 1,000 square metres and from a building on an agricultural unit and a former agricultural building to a home from 865 square metres to 1,000 square metres.
		+	* Range of commercial building uses: The range of uses agricultural buildings and land within their curtilage that can be used for commercial purposes widened. Falls 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.
		+	* New build and extension areas and volume: The ground area limit of new buildings or extensions erected on farms over 5 hectares increased 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 also increased with an extension from 20% to 25% above the original building cubic content.
		+	* Number of allowable homes: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 increased to 10, allowing up to 1,000 square metres of floorspace to change use overall. Housing delivered must meet national space standards, with prior approval from planning authority for 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.
		+	* Restrictions for scheduled monuments: Where there is a designated scheduled monument, extensions and the erection of new buildings is removed, to ensure important monuments are preserved.
