Description
Poesnant Farm is a long, two-storey building with three windows, made of white-washed rubble stone and topped with a slate roof featuring rendered end stacks. The windows and doors are slightly offset to the right and are framed with stone lintels and sills. The central entrance has a boarded door with a plain overlight above it, while to the right is a hornless 12-pane sash window. To the left, there is a double horned sash window, also with 12 panes, and a small 4-pane fire-window at the far left. The upper storey features 16-pane hornless sash windows beneath the eaves, aligned with the windows below.
Attached to the north end is a lower one-and-a-half-storey unit, now serving as a kitchen, which is also built of whitewashed rubble stone and has a slate roof with a large rendered end stack. This unit has a door on the right and a small-pane casement window on the left, both of 20th-century origin with rendered lintels. Above the left window is a 2-light 20th-century casement beneath the eaves. The rear of the main range has irregularly placed 2-light wooden casements, with three on the upper storey and two below, the rightmost window featuring a segmental brick head. The lower unit has a 20th-century window on each storey. A boundary wall continues to the right.
To the south of the house is a long farm range made of random stone on boulder footings, also under a slate roof, which runs at a slight angle to the house and is not lime-washed. The openings in this range have been altered, featuring a wide full-height doorway in the center, with a hatch and planked door to the left. There is also a wide opening with planked double doors at the left end, likely added later. To the right of the central entrance are two single doorways, one with split doors, and a very small light between them. The loft has a central gabled dormer that is now boarded over.
The main range was not inspected. The lower kitchen unit on the left has a fireplace in the end wall, which is partly infilled, and features a long timber lintel. The ceiling includes a spine beam with a shallow chamfer and plain joists. The farm range consists of four bays and is open to the roof, with tie beam trusses that contain some reused timbers, including part of a cruck blade, and has a concrete floor. There is a stable at the right end.
