Preston Mains

Preston Mains is an early 19th century, two-storey, three-bay farmhouse that includes a basement and an office addition. The building is constructed from snecked whinstone rubble with grey ashlar dressings and raised margins.

The central entrance features a door with steps and iron railings, framed by a pilastered doorpiece with a cornice. Above the door is a strip fanlight with a decorative glazing pattern. On the ground floor, there are windows flanking the entrance, while the first floor has three windows positioned close under the eaves. To the right, a stair leads to a basement doorway, with iron railings, and there is a light well for the basement to the left.

To the right of the farmhouse is a later single-storey office addition with a piend roof, which includes a tripartite window with stone mullions. The rear of the building has an entrance to the basement, with a stair window located above it between the first and second floors. The outer bays feature windows on each floor, and the office is built of brick, featuring a two-light window in the basement and a tripartite window above.

The gable end displays an irregular window pattern. The farmhouse has sash and case windows, predominantly with a 12-pane glazing pattern. The roof is covered with grey slates, and the straight ashlar skews and stacks are topped with a cornice.
