Description
Rhosigor is a farmhouse that features typical early 19th century Georgian vernacular details. It is two storeys high and has a four-window range that is unevenly divided into two sections. A lower service block, which is likely a later addition, is aligned to the north. The exterior has lined-out render over stone, with the stonework exposed in the service wing. The roof is made of slate and includes gable end and axial stacks, which indicate the division between the two sections of the building. The left section has closely spaced windows, while the right section has wider spaced windows, featuring 12- and 16-pane sash windows. There is a doorway to the right of the left section, which has a half-glazed door. The service block includes modern details. The interior was not inspected during the survey.
