Built circa 1573 by Dr John Gwynn of the Wynne family of Gwydir — descendants of Owain Gwynedd, last king of North Wales — Plasglasgwm remains an unspoilt example of a sixteenth‑century farm holding. Structural oak timbers dated 1571 and 1573 survive within the house, along with large oak lintel beams, an original brick‑lined bread oven, slate floors, oak boards, ceiling timbers and evidence of original door and window features.
Beside the farmhouse stands the Ysgubor, a barn believed to pre‑date the house, possibly to medieval times. Its slate roof, exposed queen posts, original slate floor and distinctive stone‑lintelled doorway — thought to have been reused from an even older estate building — all remain as part of its historic fabric.
After passing through owners including Lord Mostyn, Lord Penrhyn and The National Trust, the farm was last tenanted in the 1960s before standing empty for several years.
Plasglasgwm entered a new chapter in 1991, when the present owners purchased the long‑derelict farmhouse from The National Trust. With no electricity, no running water and decades of neglect behind it, the journey to bring this remarkable sixteenth‑century farm back to life began.
Over the following years, the remaining agricultural buildings were acquired as they fell out of use, allowing the owners to reunite the original farm for the first time since 1951. Guided by an ethos of long‑term sustainability and respect for its working‑farm heritage, each building was restored and converted one by one to create high‑quality guest accommodation and hospitality spaces. Alongside this, extensive work began on the gardens and surrounding grounds — reinstating the orchard, stone walls and footpaths, and shaping new landscaped areas in keeping with the historic character of the property.
In 2016, the Bottom Shed opened as a licensed coffee shop and bistro for residents and visitors — located in the lower barn once home to the bull, goats and the farm tractor — adding a welcoming social space to this beautifully restored historic estate.
Visitors can now stay in the long sheep barn, converted to accommodate six guests; the cow shed, now a superior double or twin room; and, new for 2025, the old hayloft, offering spacious accommodation for two. Larger groups can make use of additional bed spaces in the original nineteenth‑century pig sties.
Today, Plasglasgwm is nearing the completion of its thirty‑year restoration. A fully licensed premise offering period guest accommodation and an intimate setting for celebratory events, it is a place where the owners proudly say they now farm guests rather than livestock!
