Marine House and Cobblestones

Marine House and Cobblestones is a house and two cottages located in St Mawes, dating from the 18th century and refronted in the early 19th century. The front is made of painted brick resting on a rubble base, while the rear and end walls are also rubble. The building features a dry Delabole slate roof with gable ends, a rendered chimney on the left gable end, and an external truncated lateral stack at the rear. The cottages, known as Cobblestones, are constructed from cob with gable-ended roofs made of corrugated asbestos.

The main house has a single-depth plan with two rooms and stands three storeys tall, while the cottages, which are attached at right angles to the rear, also have two-room plans but the left cottage was originally a pair. The house has a symmetrical three-window facade facing south, with a central entrance that features an early to mid-19th century doorcase with consoles. The ground and first floor openings have cambered brick arches, with modern plate glass windows on the ground floor and 16-pane hornless sash windows on the first floor. The second floor has 6-pane horned sashes.

The east-facing front of the cottages, built into a slope, has a roof at two levels. The left cottage has a ground floor doorway with a panelled, top-glazed door set within a 19th century box porch, which has louvered sides and incised scrolls on the jambs. There is a modern window in the former doorway opening to the right, featuring an arched hood supported by wrought iron stanchions, and a 12-pane, two-light casement window. The first floor has a Victorian horned sash window with marginal glazing on the left and an old 12-pane, two-light casement on the right. The right cottage, Cobblestones, has a symmetrical front with a central boarded door, 12-pane, two-light casements on the ground floor, and old 12-pane horizontal-sliding sashes on the first floor. The interiors have not been inspected.
