The origins of the house at Plas yn Faerdref appear to be as a late-medieval cruck-framed hall-house, the substantial remains of which (comprising the upper end of the hall) survive as the rear wing of the Georgian front range. The character of carpentry invites comparison with Plas Uchaf (Llangar) for which a date of 1435 has been obtained via dendrochronology: it is suggested that the original house here at Plas yn Faerdref would be of similar date. The external stone walling may be contemporary with the cruck trusses. The hall-house was modified by the insertion of a chimney into the lower end, and an upper floor, c1600, then, c1820, a new front range was built, with the truncated original house becoming the service range. Some detail on the front range suggests further remodelling in the later C19, whilst retaining strong Georgian character. The house has been extensively (though sympathetically) restored, 2003.
