Braich-y-saint comprises two house, originally separate but linked by later buildings, lying at right angles to each other. Rubble built, with modern slate roofs, they are thought to date to the late 16th century.
The west house was substantially altered and enlarged in the 19th century. The second house presents as a small two-storyed building, largely original to the south elevation, but much altered to the north and west.
A barn, probably dating to the 17th century, stands to the west of the house.
