No. 4 And 5 Frogmore Road, The Round House And Lower Frogmore

No. 4 and 5 Frogmore Road, The Round House and Lower Frogmore are a former barn and granary built over a shippon, with an adjoining linhay, stables, and horse engine house, dating to around the mid-19th century. The building is constructed of local rubble stone with slate roofs, and includes inserted roof lights. The layout is L-shaped.

The shippon with barn and granary above retain four segmented stone arches, marking the original shippon doorways, and external stone steps leading to the granary door, now a window. Behind No. 5 is the former linhay and horse engine house, now known as The Round House. The structural walls of the horse engine house are still present, with inserted windows. The northwest elevation incorporates the semi-circular stone rubble piers of the former linhay, which are flat on the exterior and have weatherboarding between them. One bay of the four-bay linhay was incorporated into Lower Frogmore, which originally formed stables. A two-storey extension and a conservatory have been added to the southeast end of Lower Frogmore.

Internally, structural timbers are visible, particularly in No. 5. The buildings are designated at Grade II for their architectural interest, being a good example of a mid-19th century range of agricultural buildings converted into residential dwellings in the late 20th century. Despite the conversion, the external facades remain largely unaltered, retaining much of their original fabric, including the rubble stone piers of the linhay, the stone arches of the shippon, the stone steps to the granary, and the structural timbers. The buildings also possess group value, forming an interesting arrangement with a 17th-century farmhouse and other listed mid-19th-century agricultural buildings.
