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 from the mid-19th century. Originally arranged as two pairs plus one, the center left block features a later five-light cantilevered Tudor bay that connects the porches. The building consists of three storeys plus an attic and basement, with stucco frontages that are two bays wide, linked by one-storey 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 extends through all storeys to No. 148, and a two-storey 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, and there are panelled doorcases underneath with steps leading up. The rear of the building has long ranges.
