100 102 AND 104, HIGH STREET

This is a 17th-century farmhouse, altered in the 20th century and later divided into three separate properties at 100, 102, and 104 High Street, Royston. Originally L-shaped, with a projecting gabled wing to the left, the house was subsequently extended to form a T-shaped plan, with 20th-century additions at both ends of the projecting wing. The exterior is rendered, with stone slate, Welsh slate, and bitumen-covered roof sections. The property has two and a half storeys.

The main section has a plinth and an entrance doorway to the left end, with a chamfered surround. There are two bays to the right of the ground and first floors, originally featuring four-light, double-chamfered windows, with the ground-floor window to the right having been enlarged. All mullions have been removed, and modern casements have been inserted. A single light is positioned above the doorway. To the left of the door, on the former gable of the wing, are a single-light window to the ground floor and a blind window to the first floor. A lower addition projects from this wing and features a further flat-roofed extension to the front. The gables include cut kneeler copings. An ashlar gable stack is present on the addition, and a central ridge stack on the main house body.

The rear of the main section has a central doorway with a chamfered surround, now contained within a 20th-century glass porch, with remains of a dripmould above. To the left and right are a bay of former four-light, double-chamfered windows to the ground and first floors, all with mullions removed and replaced with 20th-century casements. A small, blind, two-light attic window is located at the right-hand end. The projecting wing to the right also has a flat-roofed 20th-century addition. The left return (numbers 100 and 102) has altered 20th-century ground-floor openings. To the first floor, three double-chamfered windows remain of the originals, with four, three, and two lights respectively, with renewed mullions and 20th-century casements. A small, blind, two-light attic window is visible here as well.

Inside, raised roof trusses, likely contemporary with the original building, form the attic storey.
