Description
Tal-y-llyn is a two-storey farmhouse, likely dating back to the 16th or early 17th century, though the original layout is unclear. It may have been initially based around the present L-shaped plan, as evidenced by window jambs in all parts of the house. The house presents a simple exterior with no distinct external divisions between its components. The walls are of rubble construction, roughcast, with sandstone dressings, and the roof is slate-covered with rendered gable-end chimneys, a central one being present on the east wing.
The east elevation is the original principal facade. An advanced, two-storey gabled wing is set to the right (north) side. This wing sits on boulder foundations with a chamfered sandstone plinth, a hollow-chamfered cornice, and moulded gable copings topped with a pyramidal finial. Mullioned and transomed windows with pedimented hoods are present on the east elevation (4-light) and the ground floors of the north and south elevations. An inscription, “1597 HW MW," appears in the tympanum (the triangular space above the window) of the south window. Square-headed 2-light mullioned and transomed windows are found on the first floors of the north and south returns.
To the left (south) of the advanced wing is a two-window range, largely restored in 1905. A round-headed door is set in a square frame with a stop-chamfered moulded architrave; the spandrels (the triangular areas above the arch) feature a "G" to the left and an "M" to the right, signifying George Meyrick. The keystone (the central stone at the top of the arch) is recessed and bears the date "1905" in relief, and it has a moulded hood above. A heavily studded boarded door features prominent strap hinges with cusped terminals. To the left is a reset (moved) 3-light mullioned and transomed window with a pedimented hood. A stepped plinth leads to the doorway. Above the door is a narrow 4-light sash window with a segmental head, and to the left of that is a broader 4-pane horned sash window. The west elevation of the south wing has a 3-window range; a two-light mullioned window is present on the ground floor right with a straight moulded label (possibly reset), while the other windows are 4-pane sashes of varying sizes. Modern casements occupy the two windows to the left.
The north wing has boulder foundations with a broad rendered plinth on the east gable. The main north elevation is an asymmetrical three-window range, and the hipped porch entrance is offset to the right (west). Windows are widely spaced and a mixture of 4-pane sashes and casements, generally square-headed, except above the door, which is segmental. The east gable has a 4-pane casement window to the first floor. The right (west) gable elevation has two blocked small square-headed windows with moulded sandstone architraves (one per floor), suggesting the north wing also dates from the 17th century or earlier. The rear (south) elevation of the north wing features two 2-light mullioned windows to the ground floor, with straight moulded labels, and 4-pane sashes to the first floor.
