Lor Hellyas Including Adjoining Former Shippon and Front and Rear Garden Walls

Lor Hellyas is a farmhouse with an adjoining former shippon and garden walls, dating from the 17th century, with remodelling in the 18th and 19th centuries. The house is constructed of granite ashlar and granite rubble with granite dressings, with an asbestos slate roof over the main house and grouted scantle slate roofs elsewhere. The stacks are of dressed granite over the gable ends of the original house, while a brick chimney serves the 19th-century single-storey kitchen wing.

Originally a 2-room-plan farmhouse with a larger kitchen to the left and a parlour to the right, the plan was altered in the 18th century, with rebuilding of parts of the front and rear walls, resulting in shallow service rooms at the rear. In the 19th century, a single-storey kitchen was added to the left and a shippon to the right.

The front of the original house has a slightly asymmetrical 3-window arrangement. An original chamfered granite doorway is located slightly right of centre. The right-hand section of the front wall has a granite ashlar facing dating from the 18th century, which includes a 19th-century ground-floor window opening between two blocked 18th-century window openings, with a heightened 18th-century opening above the left-hand opening, and a blocked window above the other. Other openings are either 19th-century or later remodellings of older openings, with the exception of openings in the rear wall. 19th-century single-storey additions project on either side of the house. The windows are a mix of late 19th-century 4-pane sashes and 20th-century replacements.

Inside, the original kitchen has a large 18th-century granite fireplace with a domed granite oven behind the right-hand jamb, and original 17th-century chamfered hardwood ceiling beams. A well is located under the floor, and a large fireplace is present in the 19th-century kitchen.
