Description
Caer Mena is a house featuring three symmetrical bays and three storeys with a basement. The exterior is finished with painted and scribed roughcast walls and a slate roof that has moulded and corbelled eaves, along with roughcast end stacks. The central doorway is highlighted by a panelled door that includes inserted glazing in the panels.
The outer bays are designed with two-storey bay windows supported by iron brackets. These bay windows are detailed with thin attached colonnettes, blank panels between the storeys, and hipped roofs topped with iron cresting. The lower storey windows have leaded lights with coloured glass positioned above the transoms, and sash windows on the sides. The middle storey features cross windows that incorporate casements. The central bay includes a 4-pane sash window in the middle storey, which is accented by moulded bands below the sill and lintel. In the upper storey, each bay has a 4-pane sash window set beneath a moulded cornice on corbels, with a string course above.
The basement, likely part of an earlier school, has small-pane sash windows flanking a central doorway. The forecourt is enclosed by iron railings on a dwarf wall, which are adorned with decorative finials and pyramid finials on the main stanchions. The double entrance gates and a basement gate to the right feature similar detailing.
At the rear of the property, there is a lower wing with a hipped roof. The building has not been inspected.
