A late C18 or early C19 farmhouse, thought, by the owner, to have been used an early meeting house for Baptists. Tyddyn Waen is not marked on the Tithe Map of the parish of Llanrhuddlad dated1843, however, the map is poorly annotated, not all the buildings are shown and none of the agricultural buildings are recorded. The Census Returns of 1841, however, record it being a reasonable sized smallholding of over 30 acres(12.2 hectares), owned and farmed by Hugh Price.

The roof is of heavily grouted small old slates, with stone coping and rendered gable stacks with dripstones and capping, that to the back kitchen raised with brick. The entrance elevation faces SE and has a central doorway with rough stone voussoirs, flanked by widely-spaced windows. The windows are 12-pane hornless sashes with stone sills, the ground floor windows with rough stone voussoirs, the first floor windows directly under the eaves.
