Architecture - Thermal Performance - Interior Design - Project Management

We are Canberra-based residential designers, creating comfortable, sustainable and delightful homes tailored to how you live.

​​

At Tranquil Architecture, we help homeowners across Canberra transform the way they live—whether through a small home improvement, renovation, alterations and additions, secondary dwelling, or a complete knockdown rebuild.

​

Our focus is on designing functional, beautiful and energy-efficient homes that respond to your lifestyle, your site and your budget.

​

We are an experienced Canberra architecture team specialising in residential design, particularly renovations and high-performance new homes. From early concepts through to approvals, tendering and construction, we guide you through every stage of the process—managing the detail so you can feel confident and enjoy the journey.

​

Our Director is Reiné Williams, a Canberra architect and thermal performance assessor with over 20 years’ experience, and 2025 Canberra Micro Business Woman of the Year. Reiné brings a practical, performance-driven approach to design, with a deep understanding of how homes function and feel. She specialises in reworking existing homes and designing thermally efficient new builds that are highly functional, cost-effective and comfortable year-round.

​

Paul Williams, our business manager and thermal performance assessor, brings a strong technical background as a former civil and structural engineer. His expertise in construction detailing, building systems and 3D modelling ensures each project is carefully resolved and delivered with accuracy.
