Description
Gorphwysfa is a single-storey quarryman's cottage with a symmetrical two-room layout. It is constructed from snecked rubblestone blocks and features a slate roof with internal end stacks. On the front, there are two-pane sash windows on either side of a slightly offset panelled half-glazed door, which is topped by a narrow overlight. A low wall with short spear-headed railings is located at the front, and there is a later lean-to addition on the right gable end. The interior was not accessible at the time of the survey.
