Gelli Faia

Gelli Faia is a Regency villa, likely dating from the early 19th century, situated near a square plan. The villa is constructed with whitened roughcast walls, accented by Tuscan pilasters that define the bays, and a pyramidal slate roof supported by bracketed eaves, with a central rendered stack. A continuous lean-to extension is present along the lower storey, resembling that found at Plas Ynys Tywyn and built for Madocks’ engineer John Williams.

The west-facing entrance front has unequal bays in the lower storey, articulated by pilasters. The entrance bay is offset to the left of centre, featuring a half-glazed panel door flanked by Gothic pointed side lights. Renewed glazed doors are found in the outer bays, with the right-hand bay wider and designed to accommodate French doors. The upper storey exhibits two two-light casement windows.

The south garden front similarly features two upper-storey windows, alongside a flat-roofed extension from the 1980s. This extension has a wide central bow window flanked by three-light windows. The east front has two upper-storey windows, replacement glazing, and openings designed for French doors. An inserted window is found on the left side of a flat-roofed extension.

A higher service wing extends from the north side of the main house, incorporating two storeys and an attic beneath a half-hipped roof. The west end wall of the service wing is set back from the main house's entrance front. It contains sixteen-pane sash windows in the lower and middle storeys and a nine-pane sash window in the attic. A two-storey projection is located on the right side, incorporating small-pane sash windows in the north wall and a two-light window over a more recent 20th-century gabled addition at right angles. The north face, built of rubble stone, abuts a sheer cliff face and includes an inserted upper-storey window and dormer on the left side. A narrow, single-pitched projection with a corrugated iron roof features a round-headed door and vents, serving as a pantry or game store. The eastern side of the wing extends beyond the main house; its two-window east wall has replacement windows, with an attic cross window, plus a small-pane window in the upper storey and paired eight-pane sash windows to the attic under a gable on its short south wall..

The central entrance hall provides access to the main rooms on the right and rear, service rooms on the left, and the staircase situated on the left side. The hall is characterised by elliptical arches with panelled soffits, and a steep, semi-circular newel staircase with a balustrade leading to the landing. Main rooms include outer chambers within the lean-to, featuring quadripartite plaster vaults. A quarter-turn service staircase is located at the service end. Panelled shutters remain in the main rooms.
