Melin Rhosfawr is a three-storey windmill tower that stands at full height. The tower features a sloping circular wall made of mortared rubble masonry, which is partly rendered, and it is currently roofless. The ground floor has a doorway with a cambered head made of voussoirs, and the window openings on the first and second floors also have voussoirs at their heads. The interior was not inspected during the survey.
