The publication marks Hassell's 75th anniversary. With 14 studios in Australia, China, South East Asia, and the UK, the practice works across a number of fields including architecture, interior design, and landscape architecture.

MULTITUDES examines the work of multi-award winning international design practice, HASSELL. Founded in Australia in 1938, HASSELL has grown to become one of the world's largest design firms, with offices in China, Singapore, Thailand, the United Kingdom and Australia. Released to mark the practice's 75th anniversary, MULTITUDES unpacks the collaborative, multidisciplinary design approach that has seen the practice thrive in the turbulent, increasingly globalised conditions of the 21st century city. The book features contributions from leading design practitioners and commentators, including Elizabeth Farrelly, author and regular Sydney Morning Herald columnist, John Worthington, founder of international planning and architecture firm DEGW, and Professor Sue Anne Ware, of RMIT University, amongst others. Showcased projects include much of HASSELL's recent urban works in Asia's burgeoning mega-cities, as well as its signature public buildings, such as the Adelaide Festival Centre (1980), the Sydney Olympic Park railway station (1998), The National Institute of Dramatic Art, Sydney (2002), and many more. A hardback, clothbound volume with design by renowned creative studio Fabio Ongarato Design, MULTITUDES is richly illustrated and makes for a proud addition to any architectural library or personal collection.
