Cathi Colla Architects are a small team in Melbourne creating unique homes and spaces that inspire and nourish the soul. 

The spaces we design encourage good health and speak to the purpose of you and your people while minimising impact on our natural resources.

Our focus is on you.

Being a small team, we can be what so many clients want – flexible. Small makes us adaptable, approachable and great listeners, helping you discover the right design for you, distinctly based on you and your individuality.


Sticking to a clearly defined process means that we can spend more time being creative, making sure that we deliver a result that brings pleasure to all.


We’ve been lucky to work with some amazing clients and collaborate with great people. Here’s a selection of some of our favourite projects.


Cathi and her team are nothing short of amazing. Cathi had an excellent manner throughout the construction process and was great – troubleshooting problems and solutions. Everything with Cathi was done on time, on budget and in a professional manner.  The best part of the whole process is she made our house immediately feel like a “home.” She listened to what we wanted, processed it, and elevated it to a level beyond our expectations.
