The Callam Offices are an office complex in Canberra, Australia, designed by Australian architect John Andrews and known for its distinct late twentieth-century structuralist architectural style. The complex is located in the Woden Town Centre in the suburb of Phillip and was designed for the National Capital Development Commission (NCDC). The complex was initially planned to be a "megastructure" consisting of 26 suspended office "pods", however only three such units were realised. The offices were constructed between 1977 and 1981 and are one of several office complexes commissioned by the NCDC in the 1960s and '70s.[1][2][3][4] Upon completion, the offices initially served as the Woden TAFE College and have since hosted a variety of clients including departments of the ACT Government.[1]

Overview

Andrews’ design firm, John Andrews International, was commissioned by the NCDC after the 1971 Canberra Flood which claimed the lives of 7 people and injured a further 15 people. In response, design work began in 1973 on the Woden Government Offices or East Woden Offices[5], an expansive complex consisting of 26 suspended or "floating" office pods for the accommodation of Government offices.[1] The complex was to be suspended over the Yarralumla Creek floodplain. Construction was planned to begin in 1975, however that year the federal government cut funding to most government projects and construction of the complex was subsequently cancelled. Following this, the project was partially revived as the NCDC decided to build three of the pods to house the Woden TAFE College, and this construction took place between 1977 and 1981 as the Callam Offices.[1][2]

Andrews also designed the Cameron Offices in Belconnen, which alongside the original Callam Offices design concept were two products of the NCDC’s commissioning of a number of modular "mega-structure" complexes in Canberra - the other projects including the Edmund Barton Building, the (now demolished) McLachlan Offices, and the Benjamin Offices (also demolished). These complexes were built with the intention of being Government office buildings and each exemplify combinations of international[1], structuralist, and brutalist design.[1][2][4][5]

Structure

The Callam Offices exist as a modular system of structural elements, including office pods, service towers, and a central transition structure, among other elements.

The three office pods are connected to accompanying structures, as described in a heritage listing document by the Australian Institute of Architects:

The complex as constructed includes one transition space; one central circular lift and stair well tower; three circular service towers; two circular concrete fire-stair towers; one open link lobby; one mid-level open walkway either side of the central lift and stair tower, and two enclosed elevated links either side of the central lift and stair tower.[1]

An additional uncovered elevated walkway crosses the Yarralumla Creek to the south-west of the complex.

The structure exhibits a number of elements typical of the structuralist style. These elements make up the unique structural system of the complex, and include compression masts, thickened cable stays forming triangular steel supports to roofs and floors, a reinforced-concrete support structure, and sheathed anchor points of post-tensioned cables.[2]

Legacy

Design elements and concepts used by Andrews in his design for the Callam Offices were reintroduced in later projects of his. His design for 3400 International Drive (Intelsat Headquarters) in Washington, D.C. can be considered a derivation of the Callam Offices plan, as it also involves "pods" with similar size and octagonal geometry, as well as circulation towers and walkways.[6]

Environmental systems and considerations, as well as an octagonal pod concept were also carried into Andrews' design of the Octagon office complex in Parramatta, New South Wales.[6]

The Callam Offices were added to the ACT Heritage Register in 2008.[2]
