The firm celebrated its 100th anniversary in 1989. In consolidating the future of the practice, Graham Thorp invited Andrew Andersons to join his son Anthony, together with Peter Watt, Peter Harvey, Anthony Rossi and John Bilmon as partners in the firm.
With the 1990s economic recession in Australia, two directions for the firm were precipitated. Firstly, the ‘Peddle Thorp Partnership’ business model managed and led from Sydney was reframed as a group of independent Peddle Thorp offices in each city or country. The Sydney office repositioned its local design focus through a renewed engagement with the harbour of Sydney by providing a range of urban design, residential and master planning - led refurbishment projects of the harbour foreshore.
These landmark projects, incorporating civic, residential and sporting uses, were undertaken as joint ventures with other well-established Sydney practices in the lead up to the 2000 Sydney Olympic Games. Iconic state and national theatre and gallery projects as well as innovative commercial projects were also completed, several of which involved the firm in the role of executive architect.
Secondly, there was renewed focus by the Sydney office on consolidating east Asia and Middle East projects and collaborations following the success of the 1992 Shenzhen Development Bank design competition in partnership with Hua Yi Designing Consultants, Hong Kong. PTW Architects, as a partner in the consortium of Arup, China State Construction Engineering Corporation (CSCEC) and China State Construction International (Shenzhen Design Institute) (CDDI), was successful in winning the 2004 competition enabling the design and construction of the ‘Watercube’, National Swimming Centre for the 2008 Beijing Olympic Games. In 2004 the firm received Wholly Foreign-Owned Enterprise (WFOE) approval and opened offices in Beijing and Shanghai. PTW Architects continued to undertake several venture projects with CCDI in the ensuing years.
