The project at Plas yn Rhiw
Plas yn Rhiw is currently undergoing extensive conservation and restoration work to safeguard its future. This project addresses key structural, and preservation needs, ensuring the long-term sustainability of Plas yn Rhiw for future generations. While the house remains closed, we are keen to share updates on the progress and impact of this essential work.
Re-Roofing Project (Autumn/Winter 2023)
The re-roofing of Plas yn Rhiw was a significant undertaking, involving the replacement of 4,839 Welsh slates from the Penrhyn quarry while preserving as many original slates as possible. Severe water damage weakened the roof, meaning a full restoration was essential to protect the building and its collection.
An additional challenge to this project was the presence of five swarms – around 50,000 Welsh black honeybees – living in the roof. The bees were carefully rehomed in temporary hives during the restoration. Once the work was completed, they were safely returned to their newly restored home.
This project was funded by proceeds from the sale of a property in the Keating sisters' estate, ensuring that their legacy continues to support the preservation of Plas yn Rhiw.
Stairs Restoration Project (April 2024 – Present)
In summer 2023, structural movement in the staircase raised safety concerns. Investigations found dry rot in the timbers, requiring urgent repair. The staircase was deemed structurally unsafe, prompting a two-phase restoration plan. Phase 1, that took place from September to November 2024, involved the removal and replacement of the top-flight staircase, dry rot treatment, and structural enhancements. Phase 2, which will take place after the floor project is completed, will focus on decorative restoration and finishing touches.
This work, also funded by the Keating sisters’ legacy, will ensure a safe and historically sympathetic restoration of the staircase, improving both structural integrity and presentation.
Floor Strengthening Project (April 2024 – Present)
During the re-roofing project, the house’s floors were assessed because of noticeable movement. It was found that the study and Bedroom 3 were unsafe and needed strong reinforcement. The work includes adding steel supports, replacing damaged joists, repairing floor spaces while keeping original materials and making sure everything meets heritage preservation standards. This restoration will improve both the safety and long-term stability of Plas yn Rhiw.
Project Timeline and Future Updates
Phase 1 of the staircase restoration has been completed. Phase 2 and the floor restoration are pending listed building consent, with work estimated to commence later in 2024. The full reopening of the house is projected for autumn 2025.
