Description
Siamber Wen is a two-and-a-half storey, three-bay farmhouse located on a sloping site and currently in derelict condition, with windows and doors removed and most of the roof missing. The walls are constructed of rubble stone, and what remains of the slate roof is supported by coped gables on moulded kneelers. There is a brick stack to the right of center on the front roof slope, an external stone stack on the right gable end that has been heightened in brick, and a lateral hall stack at the rear. The front of the building faces west, with the center and left-hand bays forming the original house, separated by a full-height joint from the right-hand bay, which dates from the 19th century. The windows feature wedge lintels and stone sills, with some jambs showing inserted brickwork. The window joinery is missing. The doorway to the left of center has a brick segmental head, and there is a former doorway above it that has been blocked with brickwork.
The left (downhill) gable end has a three-light mullioned hall window, although one mullion is missing, and it features a plain chamfer. Above this window is a segmental-headed window that retains the frame of a tripartite sash. The attic includes a three-light mullioned window that has been blocked with brick. The rear of the building is dominated by the large projecting hall stack, which is set back from the downhill end. To its left is a window under a wedge lintel in the upper storey, along with a wood lintel from a blocked former opening below it. Immediately to the left of the hall stack is the wooden frame of an inserted half dormer. A lower rear wing on the left (uphill) side obscures a small upper-storey window in a dressed stone surround. This wing is built of rubble stone and has an end brick stack, with stone steps leading to a wood lintelled doorway in its gable end. The side wall facing downhill features frames of large-pane sash windows on both storeys, along with a boarded door to the right.
Inside, the original hall contains two chamfered cross beams, one of which has collapsed over the hall fireplace, while the other has survived due to a partition built beneath it to create an entrance hall. The entrance hall features a simple quarter-turn wooden staircase.
