The farm buildings south of Bryanston Home Farmhouse are a planned farmstead built circa mid 19th century for the Portman Estate. They are mainly of English Bond red brick with low pitched hipped slate roofs. It is a large complex of buildings with two parallel ranges aligned North-South. The east with cart-sheds and stables on the ground floor, a dormitory and food store above and married quarters at the north end. The west range with stables and shelter sheds, a granary above and riding stables at right angles to the north end. At the south end a large mixing house and steam threshing barn are situated at right angles to each other with root stores below. The barn has a steam engine house below and the ranges to the east were used as a saw mill, bone mill and malt mill, with apparatus inside to steam food with the waste steam. On the west side is a stock yard with arcaded shelter sheds and vaulted root stores. It is an interesting example of a planned farmstead as it was specifically designed with an emphasis on intensive feed production for the animals, in one complex of buildings which supplied its own power.
