Allen's Cider Mill stands in the crossroads village of North Granby, on the south side of Mountain Road just west of its junction with Connecticut Route 189. It is a -story wood-frame structure, set close to the road, with a gable roof and a -story shed addition. Its exterior is finished in vertical board siding. The main facade is three bays wide, with doors in the center and right bays on the ground floor, and square multilight windows in the other bays. The placement of the central door is slightly off-center. The interior contains functional equipment for making cider that dates to the mid-20th century, and vestigial remains of older equipment, including a conveyor mechanism for transporting apples into the mill's hopper. The attic space has traces of plasterwork, indicating it was a finished space, which was probably used for aging cider. and
