The elevation towards the road has gables to right and left with first floor overhangs. The two moulded bressummers of the right hand overhang and attic gable are carved with cornice battlements and suggest a 15th century date. The overhang to left has been partly bricked up. 1.2.1. window facade. 2 storeys, the centre part being the hall of 1 storey. Of particular note are the two bay windows on ground floor to right which have closely-spaced mullions and were probably inserted in the late 16th century.
