Left-hand chimney rises above taller gable of integral mill. Plan: Double depth plan houses; mill is same depth as houses and at the front appears to be integral with the house on its right. Outbuildings on the left are shallower. Mill and part of the adjoining house are probably the oldest building, slightly later the house plan was probably deepened; a little later another house was added at the right-hand end and single storey outbuildings were added at the left- hand end. The mill was probably heightened when the first house was remodelled. Both houses have 2 rooms at the front flanking central cross passages and have stair and service rooms at the rear. Breast shot wheel and machinery survive. Exterior: Mill is 2 storeys plus attic floor; houses are 2 storeys and outbuildings are single storey. South-east front. Mill has 2 window front with central doorway with loading doorway over. The front was originally symmetrical but left-hand window opening was enlarged to create a tall doorway in the C19. Old divided ledged doors and old windows. First floor left-hand window is a possibly original 12-pane 2-light casement. Cast-iron ogee guttering under the eaves. There is a corrugated-iron clad gabled dormer with wooden hoisting boom formerely used to hoist sacks of grain through a doorway to be emptied into the hoppers built into the attic floor. Houses have similar symmetrical 3 window fronts with central doorways. Right-hand house has blocked window over its doorway. This house has an old ledged door and circa late C19 horned sashes. Other house has similar C20 windows. Outbuildings (probably stables and waggon sheds) have irregularly disposed window and doorway openings with some late C19 windows and doors. Mill wheel has iron hub and segments and wooden spokes and buckets. Interior: Mill only inspected. The mill has C19 floors, roof structure and machinery. There are 2 pairs of stones on the first floor. The attic floor has hoppers at either side of an axial working floor. This mill was still working until a few years ago and has well preserved machinery.
