Great architecture shouldn't just work on paper. Led by Founder and Director Marco Spanu, Aqua Architects combines thoughtful design with technical expertise and a practical understanding of construction. Every decision is considered not only for how it looks, but how it will be approved, built, and experienced for years to come.
We believe every project deserves the same level of care, regardless of scale. As a boutique studio, we intentionally take on a limited number of projects, allowing us to remain closely involved throughout the design journey and build lasting relationships with our clients, consultants,
and builders.
Our approach is strengthened by Passive House expertise and a commitment to technical excellence, resulting in homes that are timeless, energy efficient and built to perform. Through every stage of the journey, we remain personally involved, providing the clarity and confidence needed to bring exceptional homes to life.


Our mark is built from three interlocking circles, representing the balance between creativity, functionality, and sustainability. We believe where these principles intersect is where the strongest architecture is created.
It genuinely reflects the way we approach every project, bringing together clients, consultants, and builders through a connected process that protects the original design intent from first concept to final construction.

A deep understanding of place brought Marco to Sydney twelve years ago. He saw a city defined by the same elements that continue to shape our work today: light, coastal conditions, and effortless connection between indoors and out.
Over the past decade, we've delivered dozens of bespoke homes while navigating the intricacies of planning, approvals, and construction. Our purpose is to simplify the journey and provide clarity and confidence at every stage so our clients can focus on what matters most.
