Extensions to Grade II Listed Converted Mill
Ashbury, Oxfordshire
This project involved the replacement of several poorly insulated conservatories with a series of contemporary extensions to a Grade II listed former mill. Designed to improve thermal performance and internal flow, the new additions introduce robust, well-detailed forms that remain subservient to the historic fabric.
Internally, the layout was reconfigured to resolve awkward circulation and enhance spatial clarity, with level changes and room adjacencies carefully addressed. Working closely with the client and their interior designer, we explored multiple design options to ensure the final solution balanced modern functionality with a sensitive response to the building’s heritage, with a result that was acceptable to the local authority conservation department.
