Description

Hallagather is a farmhouse dating from the 17th century, with a likely earlier core, and was remodeled around the 18th century, featuring several 20th-century additions. The building is constructed of whitewashed slatestone rubble with slate roofs, while the recent additions are not whitewashed. It has an east-facing range that is one room deep, with a stack at the south gable end. There is a second heated room in the middle of the range and a third room, which is now the kitchen, to the right. A 20th-century wing projects at the front left, and there is a two-storey addition at the rear.

The east front is two storeys high and features a four-window range, with two bays that are slightly forward under a shallower pitched roof, possibly indicating the original hall window bay. The 17th-century entrance and porch are located at the front left and are enclosed by a 20th-century addition. The porch includes a slatestone bench topped with slate and a round-headed, granite, hollow-chamfered inner door that has a cross curved in relief at the apex. There are two ground floor windows with renewed sashes and slate sills; the upper storey window has renewed casements, one of which is located under a raking roof that projects slightly above the eaves line. A second entrance with a renovated porch is situated to the right of the projecting bay.

Inside, the ground floor room at the left end of the range features a massive fireplace that is now blocked, with a chamfered granite lintel and jambs, and a slate floor. The main ceiling beams in this room are chamfered with straight cut stops. The central room has a fireplace with a chamfered granite lintel and jambs, along with a cloam oven, a slate floor, and main ceiling beams that are chamfered with bar stops. A slatestone stair with oak treads, which is blocked at the first floor, is located to the left of the fireplace. A section of the rear wall in this room has been exposed to reveal thin unjointed studding with slatestone infill. The upper storey features exposed principals, and there is a fireplace with a granite lintel and jambs in the upper storey room to the left. In the left ground floor room, there is a small wooden two-light, trefoil-headed gothic ashlar window that originally lit a stair turret; this window has been inserted into the inner rear wall, with chamfered granite mullions reused in the recent 20th-century additions.
