[1] James Birrell was appointed Architect in charge of the Brisbane City Council Architectural Department at the age of 27 years and in this capacity oversaw more than 150 projects between 1955 and 1961.

The concrete relief which decorates the lift tower at the southern end of the car park was designed by Jim Meldrum.

The original entry arrangements were altered to provide access from Turbot Street, with detail drawings of this dated 1975, and a new staircase was added to the north east corner of the building in 1992.

[1] 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.

[1] 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.

The original security screen on the Wickham Terrace elevation is a series of vertical steel rods fixed to the floor slabs with springs.

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.

A freestanding circular room, which originally acted as the main control point, is located between the two ramps from Wickham Street.

[1] Concrete finishes throughout the building were originally off-form, an unrendered surface where the impressions left by the formwork provide decorative effect.

The building, through its dramatic sculptural forms and textured surfaces, introduced the aesthetic possibilities of off-form concrete construction to Brisbane.
