Description

Chy-an-Eglos is a house and adjoining cottage dating from the early to mid-19th century. The house is constructed of granite ashlar and granite rubble with granite dressings, while the cottage is of granite rubble. Both have scantle slate roofs. The house has a hipped roof with deep eaves, and brick chimneys are located to one side and along a central axis of the cottage. Cast-iron ogee gutters are also present.

The house’s plan is of a shallow, partly double-depth design, featuring two front rooms, likely a service room behind the left-hand room, and probably a stair behind the right-hand room. A single-storey, three-room cottage adjoins the house at its right-hand end, with a wider room on the left and a lobby entrance between the right-hand rooms.

The west front of the two-storey house is symmetrical, featuring three windows. A central doorway is now protected by a 20th-century glazed porch. The windows are late 19th-century four-pane horned sashes with granite sills. The cottage is set back to the right and has a single storey, asymmetrical four-window range of late 19th-century four-pane horned sashes, and a plain doorway towards the right. The interior has not been inspected.
