Donald Insall Associates were brought in to carry out emergency repairs to a ruinous outhouse at Grade II* listed Plas Tirion, located on the edge of the Snowdonia National Park south of Conwy. The outhouse had previously been used as a cow-shed and storage barn, and contained a distinctive early cruck timber frame, dating from around 1490.
We undertook repairs to the external masonry and tiled roof, which had become unstable and needed shoring up. This process included the addition of oak timbers to the interior roof structure, and replacement of original Welsh slates. An oak screen was also replaced in the main hall, while new wooden slats were added to the gable end.
