The structural engineer was Miller, Milston & Ferris and the builder was Civil & Civic. Completed in 1989 at the cost of $200 m, the building is primarily used as a commercial office tower.

The Capita Centre is rectangular and consists of 34 levels, with a total floor area of 24,450 square metres (263,200 sq ft). The building is constructed of composite structural steel and concrete, with its support structures making it unique as it wears its structure on the outside as an outer skeleton. The external columns or lateral bracing truss are unique because they exist outside the core of the building.
