Major update over future of historic Eryri mansion and access to lake

A major update has been issued over the future of an historic Eryri mansion and access to a lake and woodland. Plas Tan y Bwlch is a 30-bedroom listed building near Blaenau Ffestiniog.

It was built in the 19th Century for the wealthy slate quarry owning Oakeley family. Eryri National Park Authority now owns the site but say they can no longer afford to run the building as a study centre.

In February, the Eryri National Park Authority decided to pursue a twin-track approach regarding the future of Plas Tan y Bwlch. This involved offering the site on the open market or partnering while simultaneously developing conversations with interested community groups to explore potential opportunities for its future use.

Following this approach, an offer was received from a potential buyer, along with interest from other prospective partners, in addition to the community group that continued to engage in discussions.

But when Plas Tan y Bwlch was initially placed on the open market in August, it raised concerns within the local community about certainty of future access to Llyn Mair and the surrounding woodlands.

The authority today said: "To address concerns, the Authority held an open drop-in session on October 14th, which was attended by 180 individuals, and further feedback was received through correspondence with National Park officers. Following a review of the comments, it was clear that one of the most important issues was maintaining access to Llyn Mair and the surrounding woodland.

"During the Authority meeting on November 13th, members voted to withdraw Plas Tan y Bwlch from the market temporarily to provide additional time for potential buyers and community groups to develop their plans. This will ensure the Authority can consider all options for the site’s future to be fully explored.

"A final decision on the future of Plas Tan y Bwlch will not be made until the Authority meeting on April 30th, 2025. At that time, members will consider a plan to retain Llyn Mair and the majority of the woodlands under the Authority’s ownership, with the intention that the remaining buildings and land will be sold or transferred to community enterprises.

"While retaining the main building under Authority ownership without a partner is no longer a viable primarily due to financial challenges, the Authority remains open to discussions with potential community groups and private buyers. Another drop-in session will be scheduled for early spring, allowing the community to receive updates on any developments and to provide further feedback on the plans before the Authority meeting in April."
