Porth Mawr House

Porth Mawr House is a 2-storey building designed in a U-plan with later additions. It features stucco fronts and hipped slate roofs with wide swept bracket eaves and a classical eaves band, along with brick and rendered chimney stacks. The main front has five windows and rusticated quoins at the ground floor, facing northwest across the garden. The small-pane sash windows have shutters on the first floor. There is an advanced central half-glazed porch beneath an overall lean-to verandah on a paved terrace, supported by trellised uprights (which have been altered at the base) and fan-traceried spandrels.

The rendered left side of the house adjoins the rear of a gateway at a right angle and features small-pane sash windows on the first floor, along with a lower 2-storey extension that has an external staircase leading to the first-floor porch. The right side has one window with tripartite sash windows and a 3-centred arch entrance with panelled reveals leading to pointed double doors.

The rear of the house has later extensions and remnants of former service buildings, such as a laundry. The interior has been significantly altered due to modern conversion into flats.
