4, College Green, and attached area railings

A house, now offices, was built in the early 18th century and altered in the late 19th and 20th centuries. It is constructed of red brick with stone and timber details, and has a slate roof with dormers at the south end. The main range is double-depth, with short wings at the rear that form a small yard.

The front has two storeys, an attic, and a basement. The seven-bay facade includes a western bay added in 1900, built to match the original. The basement walls rise to form a plinth, and a modillion cornice runs along the top. The ground floor has a central doorway with three stone steps, a Roman Doric doorcase with flanking pilasters, an entablature with a patera in the frieze, and a six-panel door with fielded upper panels. Flanking the door are sash windows with 3x4 panes in flush frames. The first floor has seven sashes similarly sized, the four left windows with thicker glazing bars. All sashes are in openings with rubbed brick flat arches, each set with raised projecting keystones. Basement windows have segmental arched heads. A cast-iron rainwater pipe with an 18th-century moulded lead rainwater head is located between the first and second bays from the right.

The west elevation of the 1900 extension has a large sash window with sidelights on the ground floor, and a single sash on the first floor. A wing to the right, with a single sash on each floor, may be earlier.

Inside, the central entrance hall contains an early 18th-century dog-leg staircase with closed strings, a column newel at the bottom, square newels with drop finials, column-on-vase balusters, a ramped handrail, and a dado. Original 18th-century joinery and moulded cornices are found in other rooms. A room on the right of the ground floor has a 19th-century white marble chimney piece with a shelf on brackets. A vaulted brick cellar is in the basement.

Mid-19th-century wrought-iron railings with anthemion finials are attached to the area.
