Gwerndyfnant

Gwerndyfnant is a T-plan house that has three distinct phases of construction from the 17th century, 18th century, and early 19th century. The crosswing, which is timber framed and covered in iron sheeting, is the oldest part and likely represents the surviving parlour wing of an earlier hall house. This hall house was rebuilt in the 18th century using neatly coursed stone, which includes the stairs, hall, kitchen, and dairy.

The house is situated on a slope, and at the upper end, there is a rubble stone range from around the 1830s that consists of service rooms below a large room with a high ceiling and a separate outside entrance. This room is accessed through a small weatherboarded block featuring elaborate Gothic details, such as pointed windows and stained glass. Both blocks have decorative pierced bargeboards and eavesboards and were reportedly used for country dance evenings. The main ranges have iron roofs that are hipped to the left, while the 19th-century ranges have slate roofs. There are three rubble stacks: a ridge stack with a moulded cap, a projecting stack at the corner of the wing, and another projecting stack with a brick upper at the front of the 19th-century range. Most of the windows have modern fenestration in earlier openings, some of which feature flat voussoir lintels, and two leaded iron casements remain at the dairy end. The rear has a six-panel, raised and fielded door, while the centre front has a four-panel door with an open timber porch.

Inside, the wing consists of two rooms with exposed high-quality square-panel timber framing, substantial corner posts, chamfered ceiling rails, two blocked door frames, and a blocked mullion window. There are also two chamfered beams with square-cut stops and exposed joists. The 18th-century range features a well-crafted moulded fire surround, a panelled wall cupboard with H-hinges in the former kitchen, and a dairy with original shutters. It also has four-panel raised and fielded doors, simple stairs with a plain squared newel and slender turned balusters, and flagstone floors. Additionally, there are two early 19th-century bedroom fire surrounds, one early 19th-century hob grate, and one later 19th-century decorative grate.
