Glan Hafren House

Glan Hafren House is an early to mid-17th century timber-framed house, representing a regional style of the Early Renaissance. It features a two-unit layout with a central stack and a lobby entry, along with a storeyed porch. A later brick outshot was added to the rear around 1840.

The house is two storeys high and constructed with box framing and close studding, which includes a mid-rail at the first floor and plaster infill. The ground floor has corner braces, and there is a stone plinth at the base. The roof is steeply pitched and covered with slate, featuring 19th-century bargeboards and oversailing eaves. A mid-19th century brick stack with four angular shafts sits on a rectangular base.

The first floor windows have timber-framed gablets and ornate pierced bargeboards, with small paned three-light casements and moulded flat hoods. The ground floor has similar windows with sloping hoods supported by brackets. The prominent gabled storeyed porch at the centre has 19th-century pierced ornate bargeboards and a finial. The attic and first floor jetty out, with a mid-rail at the first floor and a two-light small paned casement window offset to the right. The interior features dragon beams and an open porch at the ground floor, with an upper portion that originally had an open balustrade but is now infilled. The inner door dates from the 19th century.

On the right end elevation, there is a three-light small paned casement window on the first floor, a blocked central window on the ground floor, and a later pantry window inserted to the right. The left end wall has a slate-hung gable end with a triangular attic window, and a modern lean-to replaces a 19th-century extension at ground floor level. A later 17th or 18th-century lean-to outshot is located at the rear, featuring lighter square framing and wattle and daub infill. This was enlarged around 1840 in English garden wall bond brick to create a two-storey parallel range, with a later 19th-century roof and bargeboards, and small paned casements.

The house was not stained black and white before the 19th century.

Inside, the house has axial stop-chamfered beams and a plain mantel beam in the hall. The parlour features introduced 17th-century panelling, and a pantry has been inserted to the rear. The lean-to structure survives within the 1840s wing, and a mid-19th century passage has been cut transversely through the chimney breast.
