In 2021, I gained planning approval and listed building consent from Colchester City Council for the conversion of a prominent 400 sq m timber-clad barn on Mersea Island to a large family dwelling, working alongside specialist heritage and ecology consultants.

The case overcame the Council's strong preference for non-residential rural conversions, the barn's proximity to a Grade II listed building setting, bat ecology constraints and the impact on neighbouring amenity — all through a well-reasoned planning case and a high-quality heritage-led design.

Heritage Barn Conversion in West Mersea, Essex

I secured planning permission and listed building consent from Colchester City Council for the conversion of a large historic barn on Mersea Island, Colchester to a spacious family dwelling.

The barn, approximately 400 sq m in floor area, was characterised by black timber cladding and three large wagon entrances — a building of considerable historic character, but one that had also suffered a number of 20th century interventions that detracted from its overall integrity.

The application faced a challenging combination of planning obstacles.

Colchester's adopted policies resist the conversion of rural buildings in countryside locations to residential use, with a preference for commercial and community uses.

The barn fell within the setting of a Grade II listed building, precluding the use of Class Q permitted development rights and requiring a full heritage assessment.

Bat surveys identified the site as ecologically sensitive.

And the barn's proximity to neighbouring residential properties and tourist accommodation raised legitimate amenity concerns.

To address this combination of constraints, a strong team of specialist consultants was assembled — covering heritage, ecology and structural matters. Their evidence base informed both the planning case and the design approach.

A robust and well-reasoned planning statement demonstrated that the material circumstances were sufficient to outweigh the Council's restrictive policy approach in this specific case.

Colchester City Council was satisfied the proposal met the necessary tests and approved both applications.
