Description
Glan Hen Wye is a farmhouse built in the late 18th century or early 19th century. The main part of the house has a cross wing at the southeast end, which was altered in the 19th century. The exterior features painted roughcast and a hipped slate roof. The building is two storeys high with an attic, and the original structure is symmetrical, consisting of five window bays. All windows are 12-pane sashes set in reveals, although the center windows are false. There is a part-external gable stack at the northwest end, where the roof is hipped.
At the rear, which overlooks the farmyard, there are 18-paned iron casement windows of Maesllwch Estate type, framed in timber with monolithic lintels, along with a gable next to the cross wing. The cross wing is taller and features a gable facing the southeast front, with a large glazed porch above a partly glazed door and similar 12-paned sash windows on the upper floor. The cross wing also has shaped bargeboards and two stacks: one central and one on the gable. The southern elevation includes two tiers of 19th-century canted bay windows, each with 12-pane sashes.
The property was not accessible at the time of inspection in July 1995.
