Hannay House

In the Hannay House project in the Sefton Park conservation area, Maggie Mullan applied PAS 2038’s energy retrofit principles to a Grade II listed villa. The project involved adding a small extension to provide a work/living space while improving the thermal performance of the original structure.

The extension was designed using zinc standing seam cladding, complementing the existing materials while providing modern insulation solutions. Maggie ensured the design followed PAS 2038 guidelines by distinguishing between old and new elements. This allowed for the integration of high-performance insulation in the extension without compromising the villa’s historic character.

Maggie’s focus on reducing thermal bridging through careful detailing, such as ensuring airtightness and installing double glazing in the extension, contributed to the building’s overall energy efficiency. Although the project encountered challenges due to client decisions regarding contract administration, it exemplifies how modern energy efficiency measures can be sympathetically introduced into historic buildings through thoughtful design and adherence to conservation standards.
