Barn conversion to dwelling at Hedgerow Place, Berkhamsted
Summary of planning committee decision
Decided by Dacorum Development Management on 18 Sept 2025.
What was proposed
The application proposed converting part of an existing horticultural storage barn into one dwelling, with a dormer, larger windows and a defined garden area.
“The application seeks planning permission for the conversion of an existing horticultural storage barn into a single residential dwelling with associated works at land off Bullbeggers Lane.”
“The proposed works involve the conversion and modest alteration of the existing structure, including a low-profile catslide dormer, larger glazed openings, and the creation of a defined residential curtilage.”
Officer report
The site and its setting
The barn and hardstanding are in a rural horticultural setting, screened by hedgerows and trees, about 300 metres from Berkhamsted.
“The application site comprises part of an existing horticultural barn and associated hardstanding located off Bullbeggars Lane, approximately 300 metres from the edge of Berkhamsted. The barn sits within a rural setting, forming part of an established horticultural enterprise, and is enclosed by mature hedgerows and trees, which provide a strong degree of natural screening.”
“The surrounding area is predominantly rural in character, with a mix of horticultural structures, open farmland, and scattered dwellings. Access to the site is via Bullbeggars Lane, which connects directly to London Road, providing reasonable links to the town centre and local services.”
Officer report

Earlier permissions concerned the construction of the barn, temporary storage containers, drainage, boundary treatment, landscaping and related horticultural works.

Officer report
Why officers supported it
Officers considered the conversion appropriate in the Green Belt and found limited effects on openness, the AONB, neighbours, highways and future residents.
“The proposal for the conversion of part of an existing barn to a single residential dwelling is considered acceptable in principle. From a Green Belt perspective, the proportionate extension of, and the conversion of, an existing building would amount to appropriate development in the Green Belt and given the proposal does not materially harm the openness of the Green Belt or conflict with its purposes, the development is consistent with paragraph 154 of the NPPF.”
“The site is located within the Chilterns AONB. The scheme has been designed sensitively, utilising appropriate materials and retaining the barn’s linear form, and overall rural character which ensures that its visual impact is limited and that the special qualities of the AONB are preserved. The proposal does not result in any harm to the residential amenities of surrounding properties and does not give rise to any highway safety concerns.”
Officer report
The decision
Planning permission was delegated with a view to approval, subject to an appropriate assessment and legally secured financial mitigation for the habitat site.
“Resolved: That planning permission be DELEGATED with a view to APPROVAL RECOMMENDATION”
“That planning permission be DELEGATED with a view to APPROVAL subject to the completion of an appropriate assessment in accordance with article 6(3) of the Habitats Directive and securing a mitigation package to mitigate any adverse effects on the integrity of the CBSAC through financial contributions secured by legal agreement.”
