The Wickham Terrace Car Park is a multi-storeyed reinforced concrete structure located on a steeply sloping site at the edge of the
Brisbane central business district. Occupying an elevated position between Wickham Terrace and Turbot Streets the building overlooks the Central Railway Station to which it is connected by a tunnel. The entire structure, which has gently sloping floors, is a ramp which facilitates movement by cars upwards through the building. It originally consisted of seven levels at the
Edward Street end and eight levels at the opposite end. Two more floors have been added to the top of the building. Due to the sloping site three floors are below the level of Wickham Terrace. Entry to the building is at the lowest level from
Turbot Street. The main exit ramp, an addition, is roofed and leads to either Turbot Street or Wickham Terrace. The original entrance and exit ramps from Wickham Terrace remain but appear to be infrequently used. An open structure, the car park consists primarily of a grid of rectangular concrete
columns with flared tops supporting waffle slabs which form the floors. Precast concrete panels with an exposed aggregate finish form the balustrades on the Turbot Street and Wickham Terrace elevations. Balustrading elsewhere consists of painted square sectioned steel posts attached to the outside face of the building which support steel pipe
handrails. Horizontal steel rods secured with steel springs have been added as supplementary balustrading. The original security screen on the Wickham Terrace elevation is a series of vertical steel rods fixed to the floor slabs with springs. Attached to the main structure near the Edward Street and Wickham Terrace corner is a lift tower and staircase. This vertical service structure incorporates rooms on a number of levels which were originally used for such purposes as kiosk, office and public toilets. It is connected at the lowest level to the tunnel, now lined with ceramic tiles, which links the car park to the Central Railway Station and
Anzac Square. The lift tower is clad with a concrete curtain wall decorated by a relief pattern. This concrete relief pattern consists of recessed abstract shapes laid out in a repetitive grid. The staircase, which juts out beyond the lift tower, is a prominent feature with sculptural supports and cantilevered semicircular landings. The staircase has a steel rod and pipe balustrade. The floor of the lift foyer and the staircase is tiled in green and white
mosaic tiles. Dominating the eastern end of the building is a dramatic semicircular ramp which is used by cars exiting the building. A concrete staircase, similar in style to the original stair on the western end now protrudes from the north east corner. A freestanding circular room, which originally acted as the main control point, is located between the two ramps from Wickham Street. Concrete finishes throughout the building were originally off-form, an unrendered surface where the impressions left by the formwork provide decorative effect. Parts of the building have subsequently been painted. New galvanised steel balustrading and security
grilles have been installed. == Heritage listing ==
