Range of outbuildings at Rhostwarch

The range of outbuildings at Rhostwarch is constructed from rubble stone and features a slate roof. This long lofted stable and cart-shed range includes two widely separated 2-light loft windows, which have timber lintels and slate sills. On the ground floor, there is a broad elliptical-arched cart entry to the right, followed by a stable that has a window, a door, and another window. The stable windows consist of 2 lights, a single top-light, and boarded internal shutters, with cut stone voussoirs, slate sills, and ledged doors.

On the right end wall, there are outside steps made of rubble stone, leading to a slate parapet and rail, along with a ledged loft door. Attached to the left end of the building are two single-storey cow-houses that step downhill. These cow-houses have asbestos roofs, with the first one featuring three doors and the second having two doors.
