Colvennor Farmhouse

Colvennor Farmhouse is a farmhouse dating back to the 17th century, with extensions added around the early 19th century. The front is constructed of dressed serpentine ashlar with granite sills, jambstones, and lintels, while the rest of the building is of rubble. The roof is hipped, covered with asbestos slate at the front and scantle slate on the hips and rear, with a hipped projection to the right featuring a parallel gable-ended corrugated PVC roof over the original range. Brick chimneys rise from external stone breasts on the side walls, and a 17th-century stone rubble chimney sits over the left-hand gable of the rear range.

The original plan likely comprised a three-room cross or through-passage house. The lower end room remains as a kitchen, located to the rear right of a two-room central passage and stair house built around the early 19th century. The original 17th-century range extends to the rear right, incorporated into a range of farm buildings. A further extension to the rear of the left-hand room of the 19th-century house has a 20th-century lean-to partially obscuring the front of the 17th-century section.

The symmetrical front of the early 19th century is three windows wide, with a central doorway featuring a 20th-century glazed door. Original openings have been fitted with early 20th-century horned sash windows. The front of the 17th-century house is partly hidden by the 19th-century structure, and the original doorway to the passage is within a lean-to. A small window opening sits above the doorway, and a present doorway was cut in the 20th century to the right of the lean-to. A flight of rubble steps with granite treads partially obscures a hall window, the lintel of which retains a chamfered mullioned window. A similar window opening above was enlarged in the 19th century to form a doorway. Ground and first-floor openings to the right of the original house are linked to 19th-century farm buildings. One ground-floor window opening was altered to a doorway with a shallow brick arch in the 19th century, and the window above was likely enlarged or remodelled during the same period. The left-hand gable end of the original house retains a granite kneeler stone, dressed copings, and a complete 17th-century rubble chimney with a slender drip course. Inside the rear of the left-hand (lower) room is a rubble projection, possibly for the original stair.

The interior has remained largely unchanged since the early 19th century, retaining carpentry and joinery of that period or earlier. This includes a dog-leg stair and a cupboard door with H hinges. The 17th-century house is largely complete at its lower (left) end, retaining a large, partly blocked hearth, 17th-century flat-chamfered and stopped spine beams with run-out stops, and a plastered barrel ceiling in the chamber above, now subdivided and partly replastered in the 20th century. The upper end (hall and inner room) has later roof and floor structures, and the hearth at the former right-hand gable end has been removed. The precise location of the original hearth in the hall is uncertain.
