Pantgwyn including attached NW range

Pantgwyn, including the attached northwest range, is an early 19th-century country house that exhibits a mildly classical style. It has been restored around 1990 and features a colourwashed roughcast exterior with a hipped slate roof and a long low roughcast stack with 13 chimney pots. The house has a two-storey, three-window front with a rubble stone plinth, paired brackets at the eaves, and 12-pane hornless sash windows set in raised plain surrounds. The central entrance consists of a six-panel door flanked by sidelights and an overlight with a radiating bar fanlight. A projecting flat-roofed classical porch is supported by two timber Roman Doric columns and corner square piers, with a cornice featuring paired brackets. Access to the porch is via two slate steps. The east end of the house is windowless, while the west end has two windows, and the rear northeast side features a 12-pane sash window on each floor, along with a long 21-pane stair-light in the centre.

The northwest service range is constructed from rubble stone and includes a stone ridge stack and a brick end stack. Its three-window west front has 16-pane sashes on the upper floor and to the ground floor right, along with two French windows, all adorned with cut stone voussoirs. The east front comprises a two-window range of 12-pane sashes to the left, with two windows above, one window and a door on the ground floor, followed by a 15-pane stair-light at mid-level, and a ground floor 12-pane window, concluding with a further two-window range to the right, both with 12-pane sashes above and a door and 16-pane sash below. The cut sandstone voussoirs continue here. A lean-to single-storey structure projects from the north end gable, hipped at the northeast angle, with the south-facing wall of the projection featuring a blocked window above and a door and window below.

Inside, the house boasts a fine, complete early 19th-century interior, including panelled shutters, six-pane doors, and reeded ceiling borders with square corner rosettes. The entrance hall leads to an axial stair hall with broad L-plan stairs, stick balusters, a ramped rail, and scrolled tread-ends. The southwest room contains a later 19th-century arched marble fireplace with a Japanese-style grate designed by T Jeckyll, registered in 1873. The southeast room features a coloured marble fireplace from the 19th century with corner roundels and an arched recess at the west end. There is also a small northeast study and two stone vaulted cellars. The kitchen includes a fine built-in dresser, while one rear room in the service range has a heavy timber lintel above its fireplace.
