Plasau Duon

The Welsh Herald Lewys Dunn recorded in the mid-17th century the ancestors of the Evans family who were living at Plasau Duon. Lewis Evans is known to have been living in 1631 It is likely that it was his grandfather (Howell ap Rhydderch) or great-grandfather (Rhydderch ap Llewelyn) were the builders of the original house. By 1904 Plasau Duon had passed to Miss Mytton, the daughter of the Rev Devereux Mytton of Llandyssil.

The house is of the ‘’Severn Valley’’ type, with a storied porch opposite the main back-to-back central fireplace, the hall on the right, and parlour on the left. A rear wing containing the stair, with side lean-to, added later, appears to replace an earlier wing. The Cadw listing considers that the house was built around 1660, but the dating by dendrochronlogy of other similar Montgomeryshire houses with jettied first floors, such Great Cefnyberen and Glas Hirfryn suggest that Plasau Duon could have been built up to a hundred years earlier.
