Tranquil Architecture is a Canberra-based residential architecture and interior design practice dedicated to delivering comfortable, sustainable and delightful homes.

Led by Reine Williams, Canberra's Micro business woman of the year in 2025, we specialise in cost-effective, solar-passive and high-performance renovations, extensions and carefully considered knockdown-rebuild projects that maximise comfort, energy efficiency and long-term value for Canberra families.

Our practice integrates thermal performance advice at every stage of the design journey, and specialise in transforming existing homes - enhancing the functionality, sustainability and aesthetics while also improving the health and comfort of the home.

 From early concept design through approvals, tendering and builder engagement, we provide an end-to-end service model that reduces complexity and empowers clients with clarity and confidence. Our focus is on delivering exceptional outcomes that balance design quality, budget alignment and construction feasibility - enabling our clients to create homes that are truly comfortable, sustainable and delightful.
