Description
Frankwell House is a building with origins in the mid to late 17th century, featuring a lobby-entry plan believed to date back to 1668. It underwent alterations in the mid 18th century and earlier 19th century, including a conversion into two dwellings, followed by modern renovations. The exterior presents a long, two-storey roughcast front with a layout of two windows on the left and one on the right. There is a timber band between the first and ground floors, and a painted rubble base with pegged weatherboarding above. The slate roof has wide boarded eaves and a large red brick chimney stack located opposite the entry. The building features 12-pane sash windows with oak sills and flush frames, showcasing 19th-century glazing set in 18th-century openings. To the right of the center is a broad 19th-century doorcase, which has a later gabled hood and cusped bargeboards supported by fluted brackets.
The structure contains twin doorways for Frankwell House and Frankwell Cottage, with timber architraves, boarded doors, and brass fittings. The rear has a cat slide roof, while the right gable end includes two small windows and an additional window that may have been added for a bread-oven projection. The left gable end is hung with asbestos tiles, and there is a modern lean-to built on the site of a former barn that was used for wool cleaning. The rear has seen modern alterations, exposing the timber frame at the top and featuring a bricked recess to the right.
Inside, the main house retains oak beams, some of which are feather stop chamfered, along with six-panel doors. The oak staircase rising from the main room has a swept-up handrail, although the balustrade has been removed. The dining room on the left reflects Georgian alterations, featuring a twin-well ceiling and cornicing. The square panelling of the timber frame is exposed on the left end wall, and the A-frame roof trusses have two rounded purlins on each pitch, with wattle and daub partitions in the attic. There is also an inner connecting door to the cottage, which retains a cobbled floor, boarded doors, and a tightly winding narrow staircase.
