A Scheduled Ancient Monument, perhaps dating from the 12th century, Frith Hall is first documented in 1545 as a grange to the Priory at Cartmel. In 2011, JCA was appointed by the Holker Estates Company Ltd to carry out a detailed recording and condition survey of the ruin that would ultimately form the basis for an application for grant funding from Natural England under a Higher Level Stewardship scheme. JCA worked extremely closely with the project archaeologist (Greenlane Archaeology) and structural engineer (RG Parkins and Partners Ltd) to identify a consolidation strategy that would involve minimal intervention and maximum reversibility.

The ruined masonry was in very poor condition and was likely to have been close to complete collapse within a few years as the exposed coastal site and harsh Cumbrian climate was causing erosion at an ever accelerating rate. The strategy was to introduce propping and shoring using new, regularly coursed slate stone to contrast with the random limestone construction of the standing remains. The specific intention was not to confuse the history of the ruin by repairs using new limestone that would detract from the exceptional significance of the heritage asset.
