Glyn Taf

Glyn Taf is a country house of early 19th-century Gothic character, built in colourwashed rubble stone (formerly roughcast) with slate roofs and stone chimneys.

The formal west front facing the valley incorporates the end gable of a previous house as its centrepiece, featuring a renewed scalloped bargeboard. The fenestration includes a 3-light first floor window and a 1-3-1-light canted bay window below. Added wings to either side contain ground floor windows only: a canted bay to the right with 1-3-1 lights, and a 3-light window to the left. The first floor window and ground floor left window have stone voussoirs and formerly had hoodmoulds. The building once displayed stucco equal-armed crosses to the first floor of each wing and a blank loop in the main gable.

The south front is dominated by cross gables flanking an altered 17th-century side wall. The left gable has a scalloped bargeboard, a 3-light first floor window (formerly with hoodmould), and below it a pointed window and doorway both with intersecting tracery in their heads; the doorway retains its half-glazed door. A 1996 description mentions two doors at this location. Marks of a tent-roofed veranda remain visible in the former roughcast. At the junction with the main block is a narrow curved stair tower with two small pointed lights and a top parapet. To the right are two square projecting two-storey stone bays. The first bay contains a 3-light window with hoodmould over a doorway of similar style with overlight and hoodmould (formerly also a 3-light window). The second bay has a similar 2-light window with hoodmould on each floor. The right cross gable displays two small Gothic lights at different heights to the first floor and attic, with a blank slot between them, and a broad lower window with stone voussoirs and 20th-century glazing.

The east elevation shows an asymmetrical gable end of the spine range with a 3-light window and stone voussoirs. A pointed door with rough stone head stands to the right, and a 20th-century outshut with a similar pointed door is positioned on the side of the left wing of the north range. The gable was formerly not asymmetrical and carried a massive stone chimney to the right.

The rear north elevation has two gables with scalloped bargeboards flanking a rear outshut. The left gable is a late 20th-century addition in colourwashed render with two first floor pointed windows. The right gable, the end gable of the front range, displays a 3-light attic window under a hoodmould, two long first floor Gothic windows with intersecting tracery (the left one lighting the stair), and a small modern window below. Between the gables, a lean-to roof covers a former door (now a window) with stone voussoirs and two further windows, all with 20th-century glazing.

The plan, recorded in 1990 before recent alterations, shows the sitting-room occupying the centre of the west front within the original building, with a study and stair to the north. A garden room and former entrance hall were positioned to the south. A passage between the hall and stairs separates the sitting-room from a living-room still within the original range, with a boiler room beyond the chimney. The kitchen and dairy occupied the north outshut, and the upper south-east angle held a woodstore. The winding stair rose from the right side of the entrance hall and was not part of the earlier building.

The house is said to retain much Tudor Gothic detailing, including four-panelled doors and doorcases with Tudor-arched heads, fireplaces with Tudor detailing, and cornices. A simple early 19th-century wooden staircase survives, featuring stick balusters, a spiral newel, and a mahogany rail. Original roof trusses remain only at the west end, featuring bent principals with feet projecting through modern ceilings. Pegged collar-rafters in pine are found elsewhere in the roof.
