About Us

TPG Architects' directors have lived and worked in the region for more than 30 years. With numerous projects in North Queensland, from the Whitsundays to PNG, we have extensive experience in sustainable commercial, community, educational, residential and resort developments.

Our ongoing commitment to understanding our clients' requirements is reinforced by the pragmatic commercial and design skills we bring to the project, with a thorough knowledge of the construction realities of building in the tropics. This is reflected in the practice's numerous repeat clients that we have been able to assist to successfully deliver award winning projects.

With over 25 Regional, State and  National architectural awards       
TPG Architects and our directors are  the most highly commended practice in  the region.



Roger Mainwood, Director

Roger is a founding director of TPG Architects. He has unique experience in the ability to adapt needs of projects to their particular sites. He has had extensive involvement in the Cairns CBD Masterplan, initially as a consultant in 2007 and now leads the Masterplan Review in 2017. Roger was Project Manager and Architect for the original conversion of the Tanks Arts Centre and recently received State and National heritage awards for both the conversion of Wharf Shed 3 into the Cairns Cruise Liner Terminal and the Cairns Museum School Of Arts Building.  His close involvement with community groups always ensures his concepts are sensitive to the needs of users.

Roger's work on urban space and tropical design along  with his studio work with JCU Urban Design students has been recognised with his recent appointment as Adjunct Associate Professor.


Edi Piagno, Director
