Hass Farmhouse and Steading, Lockerbie

Hass Farmhouse and Steading is an agricultural and crofting settlement from the early 19th century, first shown on Crawford's map of Dumfriesshire from 1804. The site features a rectangular-plan steading range built in the early 19th century to the west, which includes a circular horsemill, and a farmhouse constructed in the late 19th century, specifically between 1857 and 1898. These buildings are situated along the roadside of the B725 Middlebie to Waterbeck road.

The farmhouse is a single-storey and attic, L-plan, three-bay structure made of coursed rubble with ashlar dressings and painted margins. The front elevation faces southeast and includes a central entrance door with a rectangular fanlight above it. Most of the windows have been replaced with non-traditional styles. The roof is slated, featuring straight skews and end chimneystacks.

The single-storey steading is rectangular in shape and has a circular horsemill attached at the southwest corner. The east elevation has a large cartshed opening with a sliding door, along with two smaller openings—one of which is now blocked—and slit ventilators. The steading roof is hipped at one end, covered in slates, and includes three rooflights on the southwest pitch. The conical roof of the horsemill is also slated.
