More Than Just Built Form

  • Wider Perspectives

    Whilst usually kept separate, By Mysa unite Architecture and Interior Design equally as an interwoven practice, enhancing each other to be more than the sum of its parts.

  • Design By Dialogue

    Through an exchange of ideas and constant refinement, we design intricately detailed places that draw people in, delight the senses, foster comfort, and mature with time.

  • Full Spectrum Service

    By Mysa has a deep knowledge of the broader industry and processes, with extensive experience across various typologies, project sizes and budgets.

We specialise in residential architecture, interior design, and bespoke commercial projects across Melbourne and regional Victoria. Whether you’re creating a new family home, renovating a heritage property, or developing a carefully considered boutique workspace, our integrated approach—with equal focus on both architecture and interior design—ensures these two disciplines are developed in unison, resulting in spaces that feel purposeful, grounded, and distinctly yours.

Our Approach

We believe the best spaces are those that evolve with you—designed to support how you live today while being flexible enough to grow and change over time. That’s why we focus on timeless design principles, high-quality materials, and thoughtful planning. The result is work that doesn’t just look good—it feels right.

Our Work

Rooted in the Swedish concept of “mysa”—to engage in an experience that is warm, comfortable, and content—we take a measured and considered approach to design. Every decision we make, from the broad architectural gestures to the smallest interior details, is informed by a desire to create places that feel embedded in daily life, loved, and entirely fitting to their context.

From our first conversation, we take the time to truly understand your lifestyle, your story, and the emotional connection you seek to create with your space. This understanding shapes every decision, resulting in an architecture and interior design outcome that feels purposeful, grounded, and tailored to you.

Our Process

Partners in design

As a bespoke architecture and interior design studio, we take a highly collaborative approach to every project. We work closely with our clients, as well as builders, consultants, and suppliers, bringing together a wide range of expertise to create thoughtful and considered design outcomes. This collective process allows us to design spaces that are not only beautiful and functional but deeply personal and enduring. We believe that great design starts with great relationships, and we approach every project with a forward-thinking, design-led approach.

Our clients often describe working with us as a truly collaborative and rewarding experience. From the initial concept through to construction and final styling, we guide and support our clients every step of the way. We pride ourselves on creating a design journey that feels thoughtful and transparent. By translating your vision into carefully considered spaces, we ensure the final result feels uniquely yours and true to you.
