Ty'n-y-Ddol

Ty'n-y-Ddol is a two-storey farmhouse dating back to the 17th century, with later additions from the 19th century. The main part of the house consists of three rooms arranged in a lobby-entry plan, with a lower carthouse range built alongside it to the right. The farmhouse is constructed primarily of local rubble stone, revealing an earlier timber-framed core and featuring roughly-dressed stones, particularly around the quoins, on the eastern side. The roof is slate, with tiled ridges and overhanging eaves and verges. The chimneys are made of rubble with weathercoursing and capping, including an early central stack that has been reduced and incorporates a modern brick flue on the south side.

The front (north) of the house has a centrally placed entrance with a flush six-panel door dating back to the early 19th century. To the left of the entrance, there is a blocked-up doorway and a break in the masonry which marks the division between the earlier 17th-century stonework and a rebuilt section to the right. Two 19th-century windows with nine panes of glass are positioned to the right of the entrance, with taller windows containing twelve panes of glass above them. A rubble wall projects at right angles to the right of these windows, returning to enclose a small yard with openings on both the north and south sides. A six-pane window is located to the left at this point, previously an entrance, with a further six-pane casement window to the right.

The rear (south) elevation features a catslide projection to the right, which was likely originally a gabled wing and was altered in the early 19th century. The openings are asymmetrical, with a small six-pane casement and a nine-pane window on the ground floor of the main block, alongside a fixed four-pane window with a concrete lintel to the left. The first floor has a modern four-pane window to the left, a modern nine-pane sash in the centre, and an original twelve-pane sash to the right.

Adjoining the main block to the west is a 19th-century carthouse with a roof raised in the mid-20th century. This block has two wide cart entrances blocked on the north side, now with modern six-pane windows supported by exposed timber lintels. A south-facing entrance with a part-glazed 20th-century door is positioned to the left, with a small original window to the right, featuring four panes of glass. Four-pane sashes have been added to the upper floor. The west gable has external steps leading to a former upper entrance, now a 20-pane wooden door inserted in the mid-20th century.

Inside, the three-unit lobby-entry plan includes a former hall to the right and a parlour to the left, with a kitchen beyond the hall. The kitchen features a Tudor-arched doorway from the 17th century and a broad, stopped-chamfered main beam, with implied joists concealed by a plastered ceiling. A section of contemporary post-and-panel partition remains to the right. A 19th-century staircase with stick balusters leads upwards to the right. The hall has a fireplace with a large, stopped-chamfered oak bressummer and rough-dressed slatestone quoins. It also features a 19th-century ceiling with plain joists, and one cruck blade is visible within the wall on the south side. The first floor has two fireplaces with polished slate, and simple neo-classical grates decorated with a meander pattern, along with panelled window reveals.
