The building is two storeys high and has a three-window range that is significantly offset to the right, placing the door well to the right of centre.

A loft light is located in the left end gable.
On the left end, there is an attached former outbuilding with its end wall rebuilt in cement block, which includes a window and door at the front. Inside, there is a central staircase, a small parlour to the right, and a large room to the left that features a fireplace with a timber lintel. At the rear, there is a former dairy in the outshut.
