Description
Upper Farm Farmhouse is a one-storey building with an attic and an irregular slate roof. The main block consists of two bays and follows a lobby entry plan, with a cross wing at the north end. This structure likely dates from two different periods, with one section containing the kitchen and the other, a wide bay that is partly timber framed, serving as the dining room. The chimney in the wing features a brick double-star plan stack. The main entrance is accessed through a shallow gabled porch added in the 20th century. The windows are timber and have been replaced in the 20th century, and there is a shallow glazed conservatory attached to the main hall. A small gabled dormer is positioned over the former hall bay.
The main living hall originally featured a central truss, likely cruck, of which the upper section remains. This includes an arched braced collar with a cusped upper face and corresponding cusped raking struts to the principals. The hall also has triple purlins, chamfered double spine beams, and a timber-framed partition leading to the north wing. A moulded timber fire lintel is present above the hall stack, and deep chamfered cross beams are found in the parlour at the eastern end of the wing, which has a heavy timber panelled wall exposed on the north side. The initials "ETC" and the date "1658" can be seen above the internal entrance door to this parlour.
