Description
Rhiwlas is a row of five mid-19th century houses located in Levant, Brynllys, Penlanfair, and The Bakery, with the first three displaying a Regency character. The houses are constructed from rendered stone, featuring stone stacks and bracketed eaves, with slate roofs; Penlanfair and The Bakery have roofs set at a lower level. They are two storeys tall, with Levant, Rhiwlas, and Brynllys also having basements. Each house has a three-window front and painted sills.
Levant features an Ionic porch with a dentilled entablature. Rhiwlas and Brynllys have half-column doorcases with uniquely shaped bulbous necks on the columns and plain entablatures. Levant and Rhiwlas have recessed doors with panelled reveals and radiating bar fanlights, while Brynllys has similar reveals but a rectangular traceried overlight. All houses boast good eight-panelled doors. The first floor has twelve-pane sash windows, and the ground floor has sixteen-pane sashes, except for Rhiwlas, which has sixteen-pane sashes on both floors. All three houses have iron railings, with Levant's featuring an additional quatrefoil pierced mid-rail. Projecting stones on the left corner of Levant indicate that the row was originally intended to be longer.
Penlanfair is finished in painted roughcast with stucco dressings, featuring twelve-pane sashes, a six-panelled door, and a traceried rectangular fanlight. It has raised shouldered surrounds with keystones on all openings, and its facade is offset to the left.
The Bakery is positioned forward of the other four houses and lacks visible stacks. It is roughcast, with twelve-pane sashes, except for the ground floor left window, which is a former shop window with twenty panes. The Bakery also has interior and exterior glazed doors with rectangular fanlights.
