Ysgwyfraith is a one-and-a-half storey house, built of local rubblestone, but with higher quality dressed stone on the east elevation which was formerly the front of the house; a datestone to the right of the door bears the initials RWM and the date 1757. The west elevation is now the front, with a shallow porch entrance of rendered brick. The upper floor is lit by three dormer windows, and there are massive stone chimney stacks at each end of the slated roof. A single-storey outshoot at the south end of the east side was a dairy, and there is a waterwheel pit on its south side.
