Greenthwaite Hall Cottage Greenthwaite Hall Farmhouse

The property comprises a farmhouse and extension, now divided into two dwellings. The core of the building dates to the mid-16th century, with alterations and additions documented by inscriptions above the entrance: "Here we consider ourselves sojourners," in Latin, along with M & D H 1650 (Miles and Dorothy Halton), and a Halton coat-of-arms dated 1660. The construction employs thick walls of pink sandstone rubble, featuring flush quoins, beneath a graduated greenslate roof with coped gables and kneelers. Diagonal stone chimney stacks are also present.

The original house is two storeys and three bays, with a left-hand three-bay extension and a lower, right-angled two-story extension of two builds, forming an overall F-shape. The main entrance to the original house has been obscured by later extensions. Chamfered stone-mullioned windows of 2, 3, and 4 lights are set beneath hoodmoulds. A 1650 porch and the left-hand extension are in a matching style, the porch featuring a Tudor-arched doorway and 2, 3, and 4-light windows with continuous hoods that extend around the side walls. The left extension incorporates a 20th-century door within a stone architrave, which serves as the present front door to Greenthwaite Hall Farmhouse. The porch and extension both feature ornamented strapwork panels between the floors. The right-angled extension displays a central stonework joint; the left section has 2, 3, and 4-light stone-mullioned windows, with the 4-light window enhanced by a strapwork panel. The right section also has a 20th-century door within a stone architrave, representing the current entrance to Greenthwaite Hall Cottage. The rear of the main house shows a central stonework joint, dividing the earlier house from the 1650 extension. Both rear sections have chamfered stone-mullioned windows of 2 and 3 lights, with one window on the left now a 20th-century doorway, all under hoodmoulds. A blocked small chamfered-surround window is visible on the left return wall, while the right return wall features upper-floor blocked 2-light windows.

The interior of the oldest part of the house possesses a large arched stone fireplace and a beamed ceiling in the principal room. The windows feature segmental splayed arches. Outbuildings, dated and inscribed HCH 1904 (Henry Charles Howard), and now used as garages, are not considered to be of architectural significance.
