Description
Garth Celyn is a late Georgian building that stands three stories tall with a three-window main front, flanked by two-storey stucco ranges. To the right, there is an in-line two-window front, while to the left, there is a two plus two window front that projects forward. The building features slate roofs and rendered brick chimney stacks, with boarded eaves on the right side. The main range has an advanced parapet and cornice, with the central bay slightly projecting.
There is a two-storey pitched roof rendered porch, which is now the entrance to Garth Celyn, featuring a stone gable parapet and a hoodmould over a half-glazed former main entrance. The ground floor has later extensions on either side. The main range and the right side have tripartite sash glazing with voussoir lintels, while the left side mostly has small pane sash glazing with a cill band on the later range.
The open-pedimented porch to Nolton Court has a half-glazed door accessed through ironwork gates with finials. There is also a pitched roof porch for Nolton Cottage, along with another porch next to the garage outbuildings at the end of a narrow drive to the left, which is entered between bull-nosed rubble gate piers. The right end wall is cement rendered and has two sash windows along with a modern porch. The rear of the building exhibits similar details, featuring a central gable and modern additions.
