Description
Mervinian House is a three-storey, three-window house with an industrial wing at the rear. It is constructed from coursed rubble masonry and features a moderately pitched slate roof with oversailing eaves and modern bargeboards. A stone stack is located at the right end, while the left end has been removed.
The second floor has modern two-pane casement windows set under the eaves. The first floor features Victorian sash windows with stone lintels. The ground floor has modern small-paned bow windows above rubble stall risers. There is an open porch at the center, topped with a cornice and supported by Tuscan columns and pilasters; this porch formerly had a balustrade on top. The entrance has a modern door.
At the rear, there is a three-storey industrial wing built of rubble masonry, topped with a gently pitched quarry slate roof. Modern windows are set under the eaves, although the windows on the top storey were originally much deeper. This wing was last used as a printing room for the "Y Dydd" newspaper but was likely a weaving loft originally.
