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.
Ongoing conservation and restoration work at Plas yn Rhiw
Caring for and looking after each property is central to our cause. During the roof renovation at Plas yn Rhiw in 2023, surveys to the stairs revealed there was dry rot in the stairs and structural weaknesses in the floors. It was decided that the house would closed to be able to undertake extensive conservation and restoration work to safeguard its future. The house at Plas yn Rhiw is expected to remain closed until July 2026, and we appreciate the patience of our visitors as we undertake this crucial work.
In 1938, the Keating family themselves embarked on extensive restoration to this house. Plas yn Rhiw was in complete disrepair and the challenges they faced were monumental. During the recent roof renovation, echoes of their challenges resurfaced. Surveys to the upper floors revealed dry rot in the stairs and structural weaknesses in the floors. With the roof completed in 2024, the ongoing building work focuses on repairing these areas.
What is the project?
In 2023, a major renovation project began, starting with the first new roof in over 200 years. 4,839 Welsh slates from the Penrhyn quarry were used while preserving as many original slates as possible. We carefully relocated five swarms of rare Welsh black honeybees. By incorporating small gaps around the eaves and under the slates, we have created spaces for bees to return.

During the roof renovation, surveys to the stairs revealed there was dry rot and structural weaknesses in the floors. The first stage of the project included the removal and replacement of the top-flight staircase and treatment to the dry rot. The second stage of this project will take place once the floor project has been completed. The work includes adding steel supports, replacing damaged joists and repairing floor spaces while keeping original materials. This restoration will improve both the safety and long-term stability of Plas yn Rhiw.
In 1938, the challenges the Keating family faced were monumental. Brambles blocked the front door, and the stream flowed through the hall, irreparably damaging the ground-floor stairs. They had these replaced with stone steps, while the upper flights remained oak.
This work, which is funded by the Keating sisters’ legacy, will ensure a safe and historically sympathetic restoration of the staircase, improving both structural integrity and presentation.
Project timeline and future updates
Now with the roof complete, our attention turns to the stairs and floors. The need for these repairs came to light during the roofing project. These essential renovations must be finished before we can reopen the house, ensuring Plas yn Rhiw can be protected for years to come. The full reopening of the house is projected for July 2026.
