Brynllywarch Hall School

Brynllywarch Hall School is an 1829 house designed in an Italianate style. It features white painted and pebble-dashed brick walls and a shallow pitched slate roof with wide bracketed eaves. The building retains triple round-headed windows at the rear and at the canted end of the rear wing. An 1887 extension at the front is three storeys high, made of yellow brick with limestone dressings and slated roofs. This extension consists of a rectangular block measuring three bays by two, with a narrower three-storey protruding bay at the front that includes a semi-circular bay of two storeys topped with an open belvedere featuring a swept lead roof supported by rustic cast iron stanchions. The northwest corner is enclosed by a raised and glazed verandah, also featuring Beaux-Arts style ironwork with elaborate brackets that cover the main double oak entrance doors. The windows are four-pane sash types.

To the west, there is a one-and-a-half-storey service wing with a heavy bracketed gable and a canted bay added around 1930. An arch-linked stack is present, and to the rear, there is a narrow service yard.

Inside, the lobby and entrance hall have ribbed plastered ceilings and oak carved dados. The lobby is separated from the large hall by a carved and glazed oak screen. There is an open stairwell at the rear of the hall, featuring a wide two-flight stair with a fretted balustrade, initialled DT, and displaying an N for Naylor in the well. The earlier rear section includes a columned gallery at the top of a separate dog-leg stair. In the staff room, there is a painted marble fireplace with a tiled and cast iron 'convolvulus' surround.
