Heartsease Barn is a grade II listed, timber framed threshing barn that was disused and in need of substantial repair. The owner wanted to bring the building back into use to provide a light and spacious conference facility in connection with his business; Radnor Hills Water, but to do so in a way that would meet requirements for accessibility, servicing, light and thermal efficiency, whilst conserving its significance and historic character.

To ensure the proposed scheme was informed by a proper understanding of its history and significance, the local archaeological trust provided a detailed survey and record of the building at the outset of the process  The outcome of this identified its capacity for change – where the character and historic fabric of original elements were conserved and protected through appropriate repairs using traditional materials, whilst allowing a more contemporary approach to the elevation affected by inappropriate 1980’s remodelling, in order to provide more natural light into the building and avoid numerous roof lights. The outcome has facilitated a use that successfully conserves and protects its historic character – both in terms of fabric and spatial layout, whilst also securing its long term maintenance, and improving thermal performance.
