Bosawsack

Bosawsack is a farmhouse that underwent significant remodelling in the early 18th century, originally being an earlier house. The building is constructed from granite rubble, featuring dressed granite quoins, lintels, and cills. It has granite rubble gable end stacks, with the right-hand stack projecting and both topped with late 20th-century brick shafts. The roof is slate with gable ends and red clay ridge tiles, and the eaves are lower at the back over the outshut.

The farmhouse has a double depth plan, likely originally designed as a three-room and through or cross-passage layout, with the lower end to the left and a two-storey porch at the front. The shallow rooms at the back were probably added during the early 18th-century remodelling, although there is no visible masonry joint at the right end, despite a well-defined straight joint at the left end. At the time of the survey in 1987, the house was undergoing extensive restoration, and the internal layout had been significantly altered; notably, the partition between the hall and inner room had been removed.

The exterior is two-storeys high with an asymmetrical three-window range, featuring late 20th-century plastic sashes with glazing bars set in former openings, all with dressed granite lintels and cills. The gabled two-storey porch is located to the left of centre and has granite chamfered four-centred arch doorways, both outer and inner, with diagonal stops, along with a granite two-light first-floor window, the mullion missing. The rear elevation also has late 20th-century plastic windows.

Internally, the house has been completely altered in the late 20th century, and there appear to be no exposed historical features remaining. Historical records from the Hearth Tax return of 1664 indicate that the house was described as "new built." Bosawsack was part of the small manor of Treworwal, as noted by Charles Henderson in "A History of the Parish of Constantine in Cornwall."
