Description

Frogmore Farmhouse is a house dating from the 16th century, with alterations made in the mid-17th century. It features a jettied porch and two crosswings added around 1935, all designed in a matching style. The main range has a steep old red tile roof, while the wings also have red tile roofs. The structure is timber-framed on a renewed red brick sill, with panelled basketwork pargetting between the exposed timbers and on the brick-built half-timbered crosswings.

The house is two storeys high and has a central chimney with a lobby entrance plan, facing south. There is a rear stair tower under a catslide roof, and the 20th-century crosswings have heavily framed jettied gables on the south side. The older part of the house has five windows along the front, with a central porch and mullioned casement windows. A tall red brick central chimney is present, which has been copied for the west side chimney of the west wing. Inside, the farmhouse features exposed timbers, including chamfered axial beams with ogee stops, and chamfered and stopped joists in two centrally heated rooms. The eastern bay has wider and heavier joists.
