The Academy was Roy Grounds’ first large building. Grounds, with his first partner, Mewton, was recognized at an early age in 1928 when a recent graduate, Grounds eventually joined Frederic Romberg and Robyn Boyd in partnership in 1953. The client, a learned scientific body, required a large conference hall with raked seating and a second larger space, the Fellows Room, as well as council rooms and offices. The Academy of Science was the recipient of the RAIA’S ’59 Sulman Award. Grounds deftly moulded these functions into a simple circular plan with circumferential circulation inside and out and housed it all in a concrete copper-clad dome. The dome functions today as designed and the interior details have been retained.

The following description is drawn from the Australian Register of the National Estate listing for Becker House:

The features intrinsic to the significance of this place are the Australian Academy of Science building, Becker House, and the moat surrounding Becker House.

Becker House consists of a flattened concrete shell which tapers off to sixteen points, creating a parabolic arch between each load point. This serves to disperse the outward thrust of the dome evenly, whilst creating penetrations in the dome and reducing the heavy aesthetic that a concrete dome creates. The structural components of the building act as a continuous entity, making the dome extremely stable, preventing movement and the need for expansion joints.

The perimeter beneath the dome is enclosed by an aluminium framed curtain wall. The planning of the internal areas is based on a radial grid and is essentially symmetrical. There are two floors with a central void known as the Wark Theatre. The theatre seats 156 people. The building also provides facilities for smaller conferences and meetings in the Council Room and Jaeger Room. The internal walls are mainly brick with simple reinforced concrete slabs creating the second floor. There are concrete beams supporting the second-floor slab across the larger open areas.

The design of Becker House paid particular attention to the sound environment, both in terms of acoustic privacy and the clarity of natural sound. The use of carpet, timber panelled walls and vermiculate ceilings, as well as extensive soft furnishings in most areas, provides a quiet atmosphere and limits unwanted sound transmission both within rooms and to adjacent rooms. The high-quality natural acoustics of the Wark Theatre was designed for speech clarity. The interior walls and the ceilings and integrated lighting provide the means of tuning the room acoustics. The asymmetric arrangement of suspended ceiling discs which act as sound reflectors and provide the main illumination of the space.

The dome is reinforced concrete graduating from a thickness of approximately 60cm at the base supports to approximately 10cm at the peak. The top half of the dome was formed in a single concrete pour. The external cladding of the dome is an overlap, interlocking copper sheeting. The outward thrust of the dome is dispersed by the moat which acts as a ring beam acting hoop tension. The moat’s second function is to diffuse and reflect the harsh Canberra sunlight under the arched overhang and into the building.

Beneath the ground of each of the sixteen load points is a concrete beam on piers taking the footings down to a solid rock foundation. The moat, beam, piers and footings are basically a continuous entity, making the dome extremely stable, preventing movement and the need for expansion joints. The dome is fully self-supporting and expresses the glass curtain wall, simply as a skin enclosing space. The building has been described as being of unconventional, futuristic design.

The construction of the dome was preceded by the building of a one-fortieth scale model constructed from fibre-glass cloth impregnated with a polyester resin. Strain measurements were taken from the model to predict the initial deflection of the concrete shell. The testing proved effective when the actual dome was constructed as it only deflected 3/8 inch in the centre.

At 45.75 metres in diameter, the Academy’s dome is larger than any other dome built before the twentieth century. Its diameter exceeds that of the largest known pre-twentieth-century dome, the concrete dome of the Pantheon in Rome which has a diameter of 43.0 metres. In diameter, it was also larger than the largest dome previously built in Australia, which was the 31.5 metre reinforced concrete dome of the Reading Room of the State Library of Victoria.

Current use

Conference, research and office facilities.

Present (physical) condition

The building is in fair to good condition.


Intrinsic value

technical evaluation:

The concrete dome of Becker House was a significant technical and design achievement for its time, and received national and international recognition.

social evaluation:

Becker House has become a landmark building and a significant tourist attraction in Canberra. On completion, it was one of the principal building icons of a modern Canberra. (Australian Heritage Commission 1998)

The building remains a prominent venue for the national and international activities of the Australian Academy of Science

The building is associated with numerous significant scientific, political and cultural figures who have been involved in either the Academy, the design and construction of the building, or in its operation over 40 years. These include:

  • M. L. Oliphant
  • D. F. Martyn
  • Clunlies Ross
  • J.C. Eccles
  • D. Mawson and ACD Rivett
  • Founding members of the Academy.

The name Becker House and a number of the rooms within the building are now named after significant

cultural and aesthetic evaluation:

The building was the first and only building constructed by the Australian Academy of Science and has a direct association with a number of prominent national and international figures in the scientific, political and cultural sectors.

The building has been successfully integrated into its surrounding landforms and roadways.

The building demonstrates clarity of design philosophy in the uncompromising, integrated and consistent architectural style and detailing of the buildings exterior and interior. (GHD 1999)

The building has a high level of design integrity, with few alterations having been made to the building fabric

Becker House was awarded the Royal Australian Institute of Architects RAIA (NSW Chapter) 1959 J.S Sulman Medal for Architectural design excellence (Australian Heritage Commission 1999)

Becker House is the only dome formed public building in Canberra. It is also one of the few buildings in Canberra to utilise interlocking flat copper roof sheeting

The original furnishings of the building (most of which remain), were designed for the building

Comparative significance

canonical status (local, national, international)

Becker House is a rare example of the use of a free-standing dome form for a 20th-century building and is one of the largest reinforced concrete, dome formed buildings in Australia and the world.

The structure of the building was a significant design achievement for its time. The dome form was a structural solution to a functional problem of creating a shape that created a pleasant atmosphere for an auditorium (Australian Heritage Commission C 1998)

Becker House is located within a precinct of buildings which house significant national collections or research establishments. The building has association with the research faculties of the adjacent Australian National University and is adjacent to Screen Sound Australia (formerly the Institute of Anatomy).

The building is exemplary of the Australian Academy of Sciences’ goal to project a public image of a progressive organisation. It is also representative of the pattern developed in Canberra to house national Institutions in purpose-designed buildings of landmark quality.

historic and reference values:

Becker House was designed by Sir Roy Grounds, one of the most significant Mid 20th century Australian Architects. It was his first major public commission. The building demonstrates many of the design principles which embody the work of Grounds. (GHD 1998)

The project was designed in the office of Grounds, Romberg and Boyd, arguably as individuals, the three most influential mid 20th Century Melbourne Architects
