Gelli Uchaf (also known as Gelli Gneuen)

Gelli Uchaf, also known as Gelli Gneuen, is a long 1½-storey house that includes a former cow house at the southern end and a taller 2-storey addition at the northern end. The building is constructed of rubble stone painted white, topped with a slate roof. The northern end features 19th-century stone end stacks, while the main range has a ridge stack. A late 20th-century stack has been added to the southern gable end.

The original part of the house has two small casement windows on each storey, with the upper storey windows being smaller and positioned beneath the eaves. The original entrance was located in the gable end, but a new entrance was created when the cow house was added. To the left of the stack, there is a boarded door that originally led to a cross passage, with a small casement window above it. A vertical joint above the right-hand jamb indicates the end of the original house. Further to the left, there is a single casement window in what was once a cow-house doorway.

The northern end features a 12-pane horned sash window in each storey, both under segmental brick heads, and a panelled door to the left with an overlight that has lozenge glazing. At the rear of the northern end, there is a sash window in the upper storey similar to those at the front. To the right, there is a half-lit door and a small window in the original house. The southern gable end has stone-lintelled doorways on both the right and left, each with boarded doors, and casement windows above.

Although not inspected, in 1994 the building was noted to contain a remarkably well-preserved wickerwork fireplace hood along with its smoke window at the rear. The farmhouse originally featured unchamfered beams and was composed of a hall with an outer room, as indicated by the position of the screen to the north of the now-blocked rear door. The outer room became heated when the 2-storey extension was added to the northern end. There are later timber stairs leading to the attic, which has a 4-bay roof with pegged collar trusses. The attic was previously lit by a window in the northern gable, the opening of which is now visible in the dividing wall between the original house and the 2-storey northern end.
