Upper Porthkerry Farmhouse dates from the 18th century with some late addition and mostly later windows. The house has whitewashed rendering, a thatched roof with ridged patterning and deep eyebrows and 3 square rubble stacks. It is two-storey with an L-shaped frontage. A plain door is beneath a thatched bonnet on wooden supports.
