Claimed to be one of the last brutalist structures left in Perth, the Hyatt Plaza is set for a $50 million makeover courtesy of a mix of local and overseas architects and the Singaporean owners of the site.

Built in 1984, the public plaza area that links the Hyatt Regency hotel and the Fortescue Metals Group building will be the focus of the redesign rather than the 367-suite hotel or Fortescue headquarters, which according to reports, are not being refurbished.

The redevelopment of the plaza is being handled by Grand Hotel Management, which is owned by Tuan Sing Holdings, also the owner of both the hotel and the adjacent Fortescue Metals Group building, which is currently the major tenant occupying approximately 70 percent of the total office area.

The architects chosen for the work include Perth-based Christou Design Group and US firm KPF (Kohn Pedersen Fox).

The site is located at the eastern end of Perth’s CBD and is bounded on the southern side by Adelaide Terrace and the northern side of Terrace Road between Plain Street to the east and Bennett Street to the west.

When complete, the makeover will give the public more access to the area with a range of facilities like a new library, childcare centre and theatre - features that were added to not only meet the brief, but also to nullify a range of community objections.
