Mercer Offices, including Brunswick Health Centre & Douglas-Jones

The Mercer Offices, which include the Brunswick Health Centre and Douglas-Jones, are a terrace of classical houses built in the mid-19th century. Originally, the terrace was arranged as two pairs plus one. The center left block features a later five-light cantilevered Tudor bay that extends over the linking porches. The building stands three stories high, plus an attic and basement, with stucco facades that have two bays linked by single-story porches. It has slate roofs, gabled dormers, and central panelled stacks. The eaves cornice and blocking course are present, along with plain pilasters above the main cornice and Corinthian pilasters below. The windows have architraves and cornices supported by volute brackets on the ground floor. There is a large later splayed bay that runs through all stories of No. 148, and a two-story splayed bay on the left side. The sash windows feature small-pane glazing, except for those at Nos. 139, 140, and 147. The side porches are adorned with Ionic columns in antis, with panelled doorcases underneath and steps leading up. The rear of the building has long ranges.
