Description
Glascoed is a large farmhouse, dating from the 17th century, constructed from a mix of timber framing and local uncoursed sandstone. The roof is covered in a combination of small, random slates, regular slates, tile ridges, and brick chimney stacks. The house has a cruciform plan, with long, two-and-a-half storey north and south wings extending from a taller, two-and-a-half storey east/west range. The north wing is slightly lower than the main east/west range, while the south wing is noticeably lower. A porch has been added to the south-east corner, providing the current main entrance.
Timber framing is visible primarily on the upper part of the east side of the house, and in the upper storey of the south wing, the gable and part of the left flank of the east end of the main range, and the upper one-and-a-half storeys of the north wing. This timber framing is filled with elaborately cut, quasi-herringbone brickwork in a warm red colour. The remaining gable end is similarly bricked in what appears to be English Bond, with bricks suggesting a later date than the original timber framing.
The remainder of the house, including the north, west, and south sides, and the chimneys, is built of sandstone. A large central chimney features a cluster of six brick stacks, four of which are laid diagonally. There is also a lateral chimney to the west of the south range with rendered twin stacks, and a truncated chimney in the north-east corner.
Most windows have steel frames with small leaded panes. Some upper and attic windows in the south gable, two upper windows of the west elevation of the south wing, and the ground floor windows of the east elevation of the north wing feature stone mullions. Stone lintels are above two attic, two upper storey, and two ground storey windows of the west gable. Two 20th-century catslide dormer windows have been added to each side of the north wing.
Inside, a very good 17th-century staircase is present, with large turned newels adorned with pendants, an elaborately carved handrail, and pierced splat balusters. Hughes describes an oak boarded and counterboarded door with wrought iron hinges and a nail-studded frame. Fine plaster ceilings are no longer extant.
