Old Mineral House, situated on the corner of Edward and Alice Streets, is a five storeyed building of rendered brick, with a cast iron and timber internal structure and timber flooring. The street facades are visually divided by rendered vertical bands imitating stonework into three bays in
Edward Street, and five in Alice Street. The ground floor level is rendered to simulate broad segmental arched openings with
keystones, some containing a pair of windows and others single large openings. The main entry is in the central bay of the Edward Street facade and has a semi-circular arched opening with flanking
pilasters supporting an austere projecting
entablature and
cornice. Paired window openings are situated in the bays on the first and second floors. These are spaced to fit the size of each bay and have rendered quoined surrounds. A
frieze with a cornice above marks the top of the original building. The same bays are continued above this to the new parapet but contain different types of window openings. On the fourth level each bay has three window openings consisting of a wide central one, flanked by narrower openings separated by small pilasters, while on the fifth level, the openings are arched. Another cornice runs around the top of the building at parapet level. Classical
pediments free of ornament are situated at the parapet level of the central bay of each street facade. The parapets step to a raised central section which stands above these. Internally the building's structure is predominantly intact. It consists of cast iron
columns supporting timber beams on the lower levels and timber beams and columns on the additional upper levels. The staircases and lifts are more recent additions. Walter's Steakhouse and Bar currently resides on the ground floor level of Old Mineral House. == Heritage listing ==
