Cathi Colla Architects was registered as a business in 2000 by Melbourne based architect and artist, Cathi Colla. Cathi has worked and taught in the architecture industry in Melbourne, Sydney, New York and in the Netherlands for many years, for some amazing architects, and across a diverse range of project types including residential, civic and cultural, community and sustainability, commercial, urban design and place-making.

Cathi embraced the opportunity to ‘do it her way’: effectively, efficiently, and beautifully – and so she did.

Cathi Colla Architects is now a talented a team who share a passion for people and community and great design – architecture with a primary focus for creating calm, beautiful, sustainable and healthy environments.

With nearly 30 years in the architecture industry, Cathi Colla has carved her niche in creating strategic design solutions, great communication with clients, consultants, builders and other project stakeholders. Cathi has worked with eminent architects in amazing locations, and on high-profile projects (Eisenman Architects in New York, Teun Koolhaas in the Netherlands, Eeles Trelease in Sydney and Denton Corker Marshall, Melbourne – just to name a few). Cathi is an architect, an artist, and a keen supporter of women in a male dominated industry.
