About Us.

The Team

At Profectus Design, we’re a small but passionate team dedicated to making the design and approval process feel easy, collaborative, and even enjoyable. Led by founder Stephen and kept grounded by our beloved Pawject Manager, Suki, we bring together technical know-how, creative thinking, and a genuine love for what we do. We believe great building design starts with good conversation, honest advice, and a deep understanding of how people actually live. Whether you're building from scratch or reimagining your current space, we're here to guide you every step of the way—with clarity, creativity, and the occasional coffee-fuelled brainstorm. Because to us, it’s not just about drawings and deadlines—it’s about creating spaces that feel just right, and making the journey just as rewarding as the outcome.

Stephen Petratos - Building Designer
Stephen Petratos
Founder & Registered Building Designer

Hi, I’m Stephen – founder and Registered Building Designer of Profectus Design and your go-to for creating homes that are not just functional, but genuinely feel like you. I’ve studied both the Diploma of Building Design and the Diploma of Building and Construction, which means I don’t just draw pretty plans—I know what it takes to actually build them. My approach is all about balancing creative vision with practical know-how, keeping designs clean, smart, and easy to bring to life on site. Outside of designing dream homes, you’ll usually find me on the tennis court—either in a social hit or chasing my not-so-secret dream of going pro. I also love a good laugh, a better book, and the occasional video game binge when the brain needs a break.

"I believe great design should feel effortless to live in—and just as effortless to build."

Cute Suki
Suki Petratos
Pawject Manager

Suki is the heart (and bark) of the Profectus Design studio. As our beloved Pawject Manager, she takes her role very seriously—especially when it comes to enforcing regular walk breaks. Her daily strolls are non-negotiable, keeping her little sausage-dog body fit, her mind sharp, and my sanity intact.When she’s not out inspecting the neighbourhood or chasing sun patches around the office, Suki is usually curled up by my feet while I work on designs. She’s got a great eye for detail (especially if it’s food-related), and her calming presence makes even the busiest days feel a bit lighter.Clients love her, the team adores her, and honestly—Profectus wouldn’t be the same without her.
