Lampen Cottage and Wheal Mary

Lampen Cottage and Wheal Mary are a pair of attached houses, originally part of a row of three, likely built in the late 18th century to early 19th century, with some alterations made in the 20th century. The buildings are constructed from slatestone rubble, with some areas rendered, and feature a slate roof with ridge tiles and gable ends. There is a gable end stack on the right and two axial stacks, one of which has a brick shaft, while the two stacks on the right have rubble shafts.

The original layout consisted of three one-room plan houses, each with a front entrance and heated by a gable end stack on the right and axial stacks on the left. Lampen Cottage, on the left, has a two-room plan, with each room heated by the axial stack. Wheal Mary, on the right, has a one-room plan heated by the gable end stack, with the entrance formerly directly into the room and an additional entrance through the rear outshut. There is a single-storey loft outshut at the rear of the entire range.

The exterior features two storeys with an asymmetrical six-window arrangement. Lampen Cottage has four first-floor windows, all of which are two-light casements, and four ground-floor two-light casements; the second windows from both the right and left were formerly doors, while the rightmost window has eight panes and L hinges. Wheal Mary has two first-floor windows and one ground-floor window on the right, all of which are two-light casements with eight panes and L hinges; the doorway on the left is blocked and has a 20th-century two-light casement inserted. All windows have timber lintels. The left end is rendered and features a 20th-century window at both the ground and first floors, with a possible former gable end stack. The right end has an external stack with an oven at the base and a small 20th-century window at the first floor to the right. The outshut contains a 20th-century door. The rear has a single storey with a loft outshut extending along the whole length, featuring 20th-century windows.
