Upper House Farm consists of a brick farmhouse, with a 16th-century timber-framed, three-bay core. This has queen strut trusses and clasped
purlins. There is a three-bay timber-framed & weather-boarded barn and also a timber-framed granary on staddle stones on the east side. A 19th century former stable closes the large farmyard on the west. Part of this farmstead is shown on the 1586 Harpsden Court Estate map. It was a typical dispersed Chiltern farmstead consisting of 116 acres in the tenure of W. Pearman (see Pearman tenure history for more details).
