Architecture + Interior Design

A considered approach to home design

Se Déa is an interior design and architecture studio dedicated to high-end residential spaces, shaped by a thoughtful aesthetic and a considered approach. Combining deep local knowledge with a global perspective, our team brings a fresh sophistication to Australian-inspired design.

Each project is customised to blend seamlessly with your surroundings and lifestyle, balancing function with a strong sense of character. By taking the time to understand your priorities and how you move through your home, we design spaces that feel personal and elevated, resulting in a home that reflects your values and lifestyle.

We create homes that feel effortless to live in and meaningful to return to.

As Seen in….

“If there’s one thing Australian designers excel at, it’s executing a clever update on the traditional beach house. One could argue it has a lot to do with our coastal upbringings, our obsession with laid-back living or even our inherently casual lifestyle, but whatever the root cause, it allows Antipodeans to create interiors with fresh vigour and singularity of vision. Such is the case for design firm Se Déa.”

WHAT OUR CLIENTS SAY…

  • "I feel incredibly fortunate to have discovered Se Déa when I did. From my very first meeting with Sam, I had complete confidence in her ability to transform our home. Her talent and expertise took our humble original design and turned it into something truly beautiful. From the initial drawings to the seamless management of the entire project, working with Sam and her team was an absolute dream. What stood out most to me was how calm and assertive the Se Déa team was throughout the process, making every step enjoyable. Their unwavering attention to detail, coupled with a focus on delivering not only functional but also clever design, made all the difference. I have absolutely no hesitation in recommending Se Déa and cannot wait to work with them again myself."

  • “About 3 years have passed since I worked with Se Déa on the transformation of my coastal apartment in Tamarama. Throughout that period, I have loved the creative interpretation of their vision for the space more and more every day; it is peaceful, elegant, comfortable and beautiful. It is a haven and not just a home. The process of working with Samantha and the team was also very enjoyable and I felt supported at all stages. I have recommended Se Déa many times since and will continue to do so.”

    — KYM ELPHINSTONE  - ART ADVISOR & FOUNDER OF CULTURAL AGENCY ARTICULATE 

  • "What began as a simple kitchen and backyard renovation quickly evolved into a full-scale design journey with the Se Déa team.  After seeing the amazing results of the first phase, we were so excited to keep going!

    The collaborative process was a standout for us. Se Déa took the time to understand our style, quirks, and love for considered design. They didn’t just listen—they challenged our ideas in the best ways possible, pushing us to think bigger and better.  Many of our most-loved features are things the team pushed us on! 

    We knew we didn’t want a traditional beach house, but we did want a home that honoured its coastal roots. Se Déa’s interpretation of that vision exceeded our expectations—unexpected yet completely aligned with our tastes. They captured what we loved and elevated it in a way that felt contemporary, unique, and truly reflective of our style."
