Description
Hill Farm House is a house dating from the late 16th century or early 17th century, which was extended and refronted in the early to mid 18th century, with later additions and alterations. The structure features a timber frame with brick casing, and part of it is rendered. The roofs are tiled. Originally, the house had an L-shaped plan, consisting of a 2-bay lobby entry and a 2-bay cross wing to the right. It is two storeys high. The entrance front is rendered, with a central door that has a bracketed hood above it. To the left of the door, there are 4-light casements. The roof is double span and hipped to the left.
There is a principal cross axial stack with three shafts: two diagonal and one central square. An 18th-century extension projects forward to the right, featuring a first-floor glazing bar sash under a gable with an end stack. The right return or garden front is made of 18th-century brick and has four windows. There are two ground floor glazed doors, one centrally located with a bracketed hood. The windows are tripartite glazing bar sashes, and the ground floor openings have gauged brick flat arched heads. A moulded brick eaves course runs along the top. There is a fire insurance sign above the door, and the roof is hipped to the right.
The left return features an 18th-century brick front that is a small extension to the original timber frame, with an entrance to the left of centre. It has 2 and 4-light casements and dentilled brick eaves below two hipped roofs. There is a gabled dairy extension to the left. At the rear of the right-hand bay, from the garden and in the inner angle of the L, is a second 17th-century stack, which is slightly extruded with an offset and has two diagonal shafts. Lean-to extensions are present in the inner angle of the L.
Inside, much of the timber is exposed. There is a large brick double inglenook fireplace at the principal stack, featuring a timber lintel with an ogee stopped chamfer. The secondary stack at the rear has a fireplace with a 4-centred arched head, and the arch and jambs are adorned with ovolo and ogee moulded brick.
