Bryn-y-Pys Estate Office

Saint Mary’s House is a two-storeyed building with an attic, dating from the 18th century and originally a three-window range with a doorway to the right. A left-hand gable return forms a full-height canted bay incorporating a chimney, and a two-window range wing beyond is part of the original structure. In 1868, the building was extended by Teulon, who added a two-storeyed, two-window range wing and a stable block to the rear. The front elevation features a six-panelled door with an overlight beneath a canopy supported by brackets, and twelve-pane sash windows with flat-arched brick heads on each floor. Similar windows are present in the canted gabled return. A deep dentilled eaves band is echoed in the ornamental caps of the original axial chimneys and repeated in Teulon’s later work, which includes a corbelled chimney to the side of the canted return. The rear wing, added by Teulon, has a wide gable with three-light wood mullioned and transomed windows on each floor, and a door within a lean-to porch in its angle to the left. There are similar windows on each floor to the left of the doorway, with a tile-hung dormer gable above. This wing is connected by a short wall to the stable block, a square building with a hipped roof, doors on either side of a central window, and a gabled dormer to the loft. Inside, the staircase has turned balusters, a swept moulded rail, and a closed string. Surviving joinery details include panelled shutters and fielded panelled doors.

The Estate Office building, which forms a single build with Saint Mary’s House, is lower in height. It is constructed of brick with slate roofs, is two-storeyed with gabled dormers to the attic, and has a three-window range. A lower, arched window with Y-tracery, lighting a room currently accessed from Saint Mary’s House, is on the left-hand side. A square bay window is also situated towards the left, with casement windows, largely obscured by ivy at the time of inspection in September 1993. The entrance is in the angle of the rear wing, which has a three-light casement window with transoms on each floor (a two-light casement window over the door was likely inserted later). An axial stack is located on the front range, and a gabled end stack is present on the rear wing.
