Bradstone Brook

The property is a house, now offices, dating back to 1791, originally commissioned for Thomas Gibson, a London merchant. It has undergone several phases of extension: to the left in the 1860s, to the rear in 1870, and a music and billiard room on the rear in the 1920s. During the 1920s, a former separate coach house and clocktower were incorporated into the main house. The construction is primarily of red and brown brick with a hipped, plain tiled roof.

The original section of the house forms the south-east corner, comprising three bays by five bays, with the central bay projecting to the return front with angled sides. The entrance front is two storeys over a basement, topped with a three-window attic under flat-roofed dormers. It features a wooden cornice and parapet, topped with a stone coping partly obscuring the roof. There are three bays with 20th-century glazing bar sash windows under gauged brick heads, and two glazing bar sash windows in arched recess panels on the ground floor. A mid-18th century doorcase, brought from another house, features a panelled door ascending seven steps with a curved end, a wrought iron handrail, an Ionic half-column surround with an open pediment, and a panelled reveal with a keystoned arch over a traceried fanlight. Extensions added in the 1860s to the left consist of five bays, two storeys high, with glazing bar sash windows under Coade stone triangular pediments on brackets to the first floor, and a brick dentil course above the ground floor. An angled bay is located to the right.

The right-hand return front incorporates an 18th-century five-bay range with a central two-storey angle bay, and a 19th-century angle bay at the right end. The windows are glazing bar sash fenestration, with casement doors to the centre of the angle bays on the ground floor, accessed by small flights of steps.

At the rear, an angle bay is situated to the left, with a stone door surround that leads into recessed centre bays. A 20th-century music room projects to the front right, featuring a wrought iron first-floor balcony. The coach house is canted at an angle to the right end. Red brick walls connect the coach house, forming a service yard, to a square clock turret on the north-west corner. The clock was constructed by Henry Triggs of Guildford.

The interior retains a stone fireplace surround, and most rooms were restored in the 1920s in a "Georgian" style. Features include detached Doric columns in the hall and a mid-18th century staircase with barley sugar balisters. The property was undergoing conversion and restoration at the time of resurvey.
