Bostock Chambers is an intricately detailed, two storey commercial building on the intersection of Brisbane and Ellenborough streets. It is complemented by adjacent buildings which form a coherent streetscape to Brisbane street. The neighbouring building, Colthup Chambers, was constructed as a separate structure and has almost identical detailing. Bostock Chambers contains shops on the ground floor with offices on the first floor that are accessed via a stair from Brisbane street. It is constructed of face brick with rendered mouldings to the upper
facade and
parapet. The
hipped roofline is concealed behind the parapet which contains the words "E. Bostock & Sons, estabd 1865" with the date of construction of the building, "1915", on the corner. The detailing to the upper floor windows is a distinctive feature of the building and includes elaborate rendered sills, and window hoods with timber
brackets, fretwork and terracotta roof tiles. Each double-hung window has nine panes to the upper sash and a single pane to the lower sash. The street
awning to the lower floor is early, and has a
pressed metal ceiling. Flat brick arches above fanlights and earlier openings are visible at the top of the awning. The ground floor shops open onto Brisbane street and are accessed from the rear through a
courtyard containing a
loading dock. A separate, single-storey building is set at an angle to the main two-storey building and houses a shop which addresses Ellenborough street. This shop contains a safe set low in one wall and a vault with a heavy metal door at the rear. The shops have been refurbished but some original fabric remains including fanlights to the shop doorways, marble thresholds and a
pressed metal ceiling to the corner shop. The individual tenancies are separated by timber vj walls. The stair to the upper floor is intact with marble threshold, double timber doors and timber stair and
handrail. The upper floor is divided into separate rooms, formerly offices, which either face the street or the rear courtyard and are accessed from a central passageway. These rooms are now used for storage and an opportunity shop. The timber doors and windows are intact and the walls and ceilings are timber framed and lined with vj boarding. The central passageway opens to an elevated walkway, above the rear courtyard, leading to a toilet block set above the loading bay. These toilets are early but not original, and consist of two ladies' and one gents' divided by a corrugated iron screen. The only handbasin is external and located on the walkway. == Heritage listing ==
