PA Architects was established in 1988 by Paul Amabile, who brought a combination of practical and award-winning building experience, with outstanding architectural and project delivery skills, to create the foundation for a successful architectural practice. Paul was shortly joined by David Liddy to form a new partnership, and the young practice quickly developed a reputation for consistent design and documentation quality, and excellence in development consulting.
In 2007, Geoff Donaldson was appointed as the new Director of the practice, which as a company structure became PA Architects Pty Ltd. Geoff had previously been an Associate of the practice, and a registered Architect with over 20 years of experience.
