3, Trinity Street

No. 3 Trinity Street is a town house, now used as an office, built in 1841. It is constructed of brick with buff headers and features stucco dressings, topped with a hipped slate roof. The building has a double-depth plan and is designed in a Georgian style, standing two storeys tall with a symmetrical three-window arrangement. The wide eaves soffit adds to its architectural appeal.

The entrance is framed by a Tuscan aedicule with a blocking course, and it includes an overlight with decorative glazing bars above a three-panel door. The windows are fitted with sills and rusticated wedge lintels with keys, and they contain 16-pane sash windows. To the left of the main façade, a small section of the building breaks back, while to the right, there is a small 20th-century single-storey addition with a top-hung sash window. The returns of the building feature modillioned brick cornices and truncated lateral stacks. This property is part of the early 19th-century redevelopment of the site of the College, which was demolished around 1799.
