Part of L-Plan range at Lower House Farm

Lower House Farm includes a 15th-century two-unit, cruck-framed former house with two additional bays added at the southeast end during the 17th or 18th century. The northwest end features a refronting and a back-kitchen wing from the 19th century. The building is constructed of rubble stone in regular coursed blocks, with a plinth, boxed eaves, and a slate roof. There is a rubble stone stack on the left and a brick stack at the rear right. Steps lead up to a central door that has a cambered voussoir lintel and a boarded door in a heavy frame. The windows are arranged regularly, featuring voussoir lintels and brick cills, though many are boarded up. The first-floor windows are very narrow and positioned under the eaves. The left-hand end bay has a weatherboarded upper floor and large double doors below.

Adjoining the former house is a barn/cowhouse range that is oriented at right angles. A partial inspection of the barn end suggests it originated in the 17th century, although some trusses and wall framing have been replaced in the 18th and 19th centuries. The external elevations are mainly weatherboarded under a slate roof, with the ground floor of the cowhouses built from rubble stone. There are boarded doors and loft shutters.

The building retains a substantial number of original cruck trusses and partition walls. The partition walls consist of large horizontal timber-frame panels filled with wattle and woven lath. The left-hand room features a large blocked fireplace with an ovolo moulded lintel, an axial beam with a deep chamfer and step stop, and exposed joists. The central room has a chamfered axial beam, exposed joists, and a large salting slab on brick piers. The right-hand room contains a chamfered axial beam with scroll stops and a small brick-lined 19th-century corner fireplace. The floors are flagged, and the roof has been raised above the cruck trusses.
