Lonon Farmhouse

Lonon Farmhouse is a farmhouse dating from the early to mid-19th century. The front is constructed of coursed slatestone, featuring dressed granite quoins, jambstones, lintels, and an ashlar course at lintel level, with slate sills. The sides and rear are made of painted rubble. The roof is a three-quarter hipped design, covered with slurried scantle slate and large slates used for the eaves course. Tall brick chimneys rise from the side walls.

The building has a double depth plan with a parlour at the front and a shallow pantry behind it. To the right is a full depth kitchen, with the stair positioned against the rear wall and a cross passage in the middle. There is a 20th-century addition at the rear and on the right side. The farmhouse features Gothic style windows and is two storeys high, presenting a nearly symmetrical three-window front on the southeast with a central doorway.

The original Gothic style windows and door remain in their original openings. The door is a four-panel design, with the top panels forming a pointed arch, and the windows are two-light casements with pointed-arched lights and glazing bars that create a Y-tracery effect. Only the left-hand light of each window opens, hung from the central mullion on pin-tail hinges. At the rear, two 16-pane hornless sash windows survive on the first floor, located in the middle and right.

Inside, the farmhouse has seen little alteration since the 19th century, featuring exposed ceiling beams, a straight flight stick baluster stair, and panelled doors. Lonon Farmhouse is an unspoiled example of 19th-century architecture, showcasing an attractive mix of slatestone and granite at the front, further enhanced by its original Gothic style door and windows. The use of granite ashlar lintel course is particularly interesting, with comparisons to nearby Hillcrest and Tregoose Farmhouse, which share similar details but date from the early 18th century.
