Our Team

Home / About Us  / Our Team
The Cathi Colla Architects team has evolved into a finely tuned boutique studio and workshop architectural practice.
Our specialty is the design of contemporary residential architecture, with a focus on the creation of calming, beautiful and healthy environments together with sustainably built homes.


Cathi Colla Architects was established in 2000. The practice began as a highly creative and experimental studio practice, balancing small architectural commissions with formal study of Fine Art, a series of exhibitions and installations, plus teaching architecture at the University of Melbourne and RMIT University.

Cathi Colla Architects enjoys assisting and educating individuals considering building or renovating their homes. The team regularly writes, develops and publishes tips and tricks on the process and benefits of good architectural design, and how to best prepare for a smooth, stress-free design and construction process.

Cathi Colla

On completing her formal training in Architecture in 1991 with First Class Honors, Cathi has passionately forged forward in her career gaining international experience in architecture and urban design whilst working with award winning architects including Peter Eisenman, New York, and BV Ontwerpbureau Teun Koolhaas Associates, the Netherlands. Since then Cathi has gained invaluable local experience with award winning Architectural practices including Denton Corker Marshall (DCM) and Williams Boag (WBa) in Melbourne; and Eeles Trelease in Sydney.

While still practising as an architect Cathi completed a Bachelor of Fine Arts (Fine Art) in 2003, majoring in Sculpture and Spatial Practice. This provided a great opportunity to explore and experiment with the concept of space, understanding the human body and its physical and psychological response to, and interaction with, our physical and subconscious environments.

Cathi’s advocacy continues in the field of architecture and achieving sustainable outcomes for our community. In 2012 Cathi became a Director for ArchiTeam Cooperative, providing her the opportunity to support the community of small practice, and sole practicing architects, as well as to advocate on the benefits of great architecture within the broader community. In late 2013 Cathi was also acknowledged as a ‘Fellow’ by the Australian Institute of Architects for her contribution to the practice of architecture over recent years.

Katherine Sampson

Katherine is a Graduate of Architecture currently navigating her registration to become an architect.

Katherine’s design expertise is predominantly within the field of residential architecture, in particular inner city and suburban sites.  She enjoys working closely with clients to see their needs turned into enjoyable and liveable solutions.

Designing and creating buildings for living is fundamentally about helping people live more efficient, connected lives. Connected to each other and the elements of space and light.

When she is not in the studio, Katherine loves connecting with nature through bushwalking and camping. Now more challenging with a toddler, but still doable! And on a day to day basis Katherine enjoys cycling to and from work.
