Porthilly Greys

Porthilly Greys is a house, possibly dating to the late 16th or early 17th century. It is constructed of stone rubble, partly rendered and painted, with a regular slate roof with gable ends to the main range and a west wing. A projecting stone rubble side chimney stack with a brick shaft is visible on the east front of the main range. Another projecting stone rubble end stack with a brick shaft provides heat to an inner room on the north side, while an axial brick stack between the hall and inner room heats a first-floor chamber.

The original plan likely comprised a three-room and through-passage arrangement, with the lower end to the right, a hall heated by a front lateral stack, and the inner room by a gable end stack. A circa 17th-century wing stands at the rear of the higher end, possibly containing the stair. Around the late 18th century, a lower service range beyond the through passage was demolished, and its truncated gable end was remodelled. In the early 19th century, the inner room was partially rebuilt, with a visible straight joint between the ranges. The through passage was likely blocked during the 19th century, the house reorientated, and an entrance inserted into the north elevation, leading directly into the west wing. The west wing was extended in the mid-19th century, and a later stair was added in a lean-to projection in the angle between the inner room and west wing.

The two-storey east front has an asymmetrical design with a two-window arrangement and a projecting hall stack to the right of centre. The ground floor features a 4 over 8 pane sash window and a 19th-century 2-light casement to the left of the stack, with a 20th-century window occupying the original entrance position to the right of the stack. The first floor has two early 19th-century 16-pane hornless sash windows. The north elevation shows the truncated gable end of the main range on the left and the west wing set back on the right, with a remodelled entrance. The remains of the lower gable end of the demolished service range on the left were remodelled in the 19th century, incorporating stepped angle buttresses, a 2-light casement on the ground floor, and a 19th-century casement above featuring a 2-centred arched opening with intersecting glazing bars. A range to the right forms the front elevation and includes a 20th-century part-glazed door.

Internally, the house was largely remodelled in the 20th century. Evidence of the former through passage remains, with a screen removed on the higher side. A blocked hall fireplace is present, along with 19th and 20th-century ceiling beams, and two circa 17th-century stop-chamfered spine beams with run-out stops in the west wing. The roof timbers were replaced in the mid to late 19th century.
