Ty Glyn including attached wings to main gable ends

Ty Glyn is a mid-to-late 18th century gentry house with a history dating back to the 14th century. A house was first recorded in 1620, built by Llywelyn Thomas Parry, and remained in the ownership of the Jones family until 1830. Henry Jones likely rebuilt the main house in 1768, and further additions were made in 1809 by his son-in-law, Reverend Alban Thomas, who incorporated a chapel. The house later passed to the Davies family, and was sold in 1964.

The house is whitewashed roughcast with slate roofs and stone end stacks. The main range is two storeys and attic, with a five-window front. It features three hipped dormers, a timber modillion eaves cornice, 12-pane sash windows, and a broad six-panel door with thick tracery above a depressed arched fanlight. A flat porch, supported by four early 19th century iron columns (two embedded in the wall), stands before the front door. The south gable is slate-hung, while the north wing is a two-storey, three-window range with 12-pane sashes, a stone left-hand stack, a blocked centre door, and curved angles. A low hipped outbuilding extends from the north end. The chapel, added in 1809, is a shorter wing with curved angles and two cambered-headed 12-pane sash windows, and includes a rubble stone bellcote with a plaque dedicating it to St. Alban and dated 1809. Evidence of a removed octagonal clock-face remains above the chapel door, which now leads to a 20th-century conservatory. A single high window is present in the rear wall. The rear of the main house incorporates a hipped stair tower between the gabled wings, with 20th-century rendering and windows. A battered wall indicates an earlier structure. The rear of the stair tower has 12-pane sash windows.

The interior features a central hall with fluted pilasters, presumably from the later 19th century, to the arch; plastered beams to rooms on either side; and 20th-century fireplaces. Fielded panelled six-panel doors are present throughout. The former kitchen has a fine fixed dresser. The chapel, accessed from a room on the right side of the house, retains a simple end gallery on two timber posts and a shallow curved plastered ceiling. A fine open-well staircase rises in four flights, featuring a moulded ramped rail, turned balusters, column newels, and an open string with moulded tread ends. Plastered roof trusses display scarfed and pegged wall posts.

Ty Glyn is included at Grade II* for its unusually well-preserved 18th century character and fine staircase.
