The section of Tre-Ddafydd that runs from north to south is a sixteenth century house. A block was added to the north, running from east to west, in the sevententh century and this was extended in the eighteenth century. There have been modern repairs throughout, but some original features of the sixteenth century house survive, including copings on the south gable, the doorway and the first floor window. The seventeenth century block includes a reset doorway from the original house.
