School extension at Blandford St Mary C Of E Va Primary School, Blandford St Mary

Summary of planning committee decision

Decided by Dorset Northern Area Planning Committee on 14 Oct 2025.

P/FUL/2025/03818Approved

The site

The school occupies a constrained site in a residential area, with playgrounds, playing fields, trees, hedgerows and a modular pre-school building.

“Issue Conclusion Highway impacts, safety, access and parking There is no demonstrable risk to highway safety, and no proposed changes to existing access or parking arrangements. Impact on trees There is no demonstrable risk to trees on the site. Biodiversity The proposal is exempt from providing biodiversity net gain as it falls below the de minimis requirement for existing on-site biodiversity features.”

“To the north of the main school building lies a modular outbuilding, originally a temporary classroom, that is currently used by the Little Birch pre-school with its own access following the northeastern boundary of the school site, again leading from Birch Avenue. The site is bounded by a combination of metal security fencing, trees and hedgerows.”

Officer report

Planning assessment

The extension was considered suitable in scale and design, with no demonstrable harm to neighbours, landscape, heritage, highways, trees, drainage or biodiversity.

“The design has been carefully considered to ensure it accords with the existing building in terms of shape, materiality and overall appearance, ensuring it reflects the character of the existing building. The development proposal would comply with Policy 24 of the North Dorset Local Plan and NP Policy B1.”

“Impact on landscape or heritage assets The site is not within any protected landscape designation, being over 300m outside the boundary of the Dorset National Landscape and almost 400m from an ancient woodland site. It is not within a designated conservation area, and there are no listed buildings within the vicinity.”
