Our designs are contextual, intentional, and practical, creating a seamless flow throughout your residential or commercial project. We balance functionality with form, using our experience and expertise to connect with place and purpose.  

Our friendly and hospitable team provide end-to-end project management, ensuring a smooth and enjoyable experience. We offer a holistic service from initial consultation and concepts to permits and contract administration. We'll guide you through every stage of the building process, working collaboratively to ensure the best possible outcome.

We have spent years developing relationships with builders and contractors, engaging with specialists who provide quality craftsmanship with attention to detail. We proactively manage your project to ensure each fixture and finish is as intended, remaining true to your vision, budget and scope.

We specialise in contemporary spaces that connect with their environment, using raw and honest materials to create a sense of modern luxury. We believe that well-designed spaces elevate moods and enrich people's lives, nurturing social connections and creating an open dialogue with nature.

In the words of renowned architect Zaha Hadid – "Architecture is really about well-being. I think people want to feel good in a space. On the one hand, it's about shelter, but it's also about pleasure."

We're Third Element Studio, the building atelier bringing purpose and pleasure to design. We’re ready to nurture your project from start to finish.
