The Project
When part of the ceiling to the West Portico of the Grade II* listed Trelissick House fell down, we were asked to complete an investigation and appraisal of the structure.
It was identified that the steelwork supporting the masonry ring beam was corroded and the laths originally supporting the decorative mouldings had rotten away causing damage to the decorative stucco moulded finishes.
Any repair works would require careful and sympathetic consideration due to the historical significance and complexity of the friezes, triglyph’s, cornices and architraves, including protection of the Doric columns below; all whilst maintaining the main access to the main building in use by the public.
It was agreed with a Local Authority Conservation Officer to remove the decorative mouldings and the ceiling to install new structural steelwork. The decorative Stucco mouldings, finishes, and lath and plaster ceiling were replaced in using lime based materials, and the original architectural mouldings were replicated and replaced.
