Who We Are
De Zande Studio is an interior architecture and design practice based in the heart of the Barossa Valley, South Australia, founded by Andrea van der Zande.
Andrea’s experience as a Project Manager at Thinc Projects and as an Associate and Senior Interior Designer at JBG Architects brings a rare blend of strategic oversight and creative vision. Her work inspired the creation of a studio that thoughtfully balances design integrity with hands-on project delivery.
Inspired by regional South Australia, the studio seeks out projects beyond the city limits—those grounded in place, character, and community. From renovations to new builds, De Zande Studio focuses on residential and small commercial projects, creating spaces that are considered, practical, and enduring.
What Guides Us
These are the values that quietly guide everything we do. They shape the way we approach our work, how we collaborate with clients and creatives alike, and the way we craft spaces that feel both personal and timeless. Each project is an expression of these principles—thoughtfully held, gently expressed.
Authentic. We believe the most beautiful spaces are those that feel honest — rooted in the lives, rituals, and stories of the people who inhabit them. Our work begins with listening and unfolds with intention—shaped by who you are, not just how you live.
Caring. Design, to us, is an act of care. It’s about creating spaces that not only look beautiful but feel nourishing. That invite pause. That support life’s rhythms. That hold you, quietly, every day.
Honest. We approach every project with clarity and kindness. There is no pretence, no performance—just sincerity. We are transparent in our process and purposeful in our choices, creating spaces that feel both gracefully resolved and deeply lived in.
Respectful. Every project sits within a broader story—of its architecture, its setting, its past. We honour that context, drawing on its character rather than competing with it. Our work is quietly resistant to trends, instead embracing a timelessness that feels both familiar and fresh.
Creative. We are endlessly curious. Each design is a thoughtful response to a unique brief—a balancing of form and function, imagination and intention. We look for the poetic in the practical, always searching for solutions that feel unexpected yet entirely at home.
Collaborative. We see design as a shared journey. Our clients, our makers, our collaborators—they’re part of the story too. Through open dialogue and trusted partnerships, we shape something more meaningful together than we ever could alone.
How We Work
INTERIOR ARCHITECTURE
At the heart of every project is a desire to create spaces that feel deeply connected—to their architecture, their setting, and the people who inhabit them.
New Builds: From the early stages of planning, we work hand in hand with clients, architects, and builders to shape interiors that not only complement the architecture but bring warmth, rhythm, and a sense of ease to everyday life.
Renovations: There’s something profoundly special about reimagining an existing space. Whether it’s a quiet update or a complete transformation, we approach each renovation with care—honouring the original character while gently layering in a new story.
Material & Finish Selection: We love guiding our clients through the tactile part of the process—exploring stone, timber, tile, and tone. Together, we craft palettes that speak to how you want to live, feel, and move through the space.
Custom Design: From bespoke kitchens to handcrafted joinery, every detail is an opportunity to shape a home that is both deeply functional and beautifully personal. These are the pieces that anchor a space—and that often become the most loved.
INTERIOR DECORATION
Decoration is where the soul of a space really comes to life. It’s in the layering of light, colour, shape, and sentiment—the art of creating atmosphere.
We thoughtfully curate furniture, lighting and rugs that feel both refined and relaxed. Every choice is made with intention—whether sourcing vintage pieces, collaborating with local artisans, or designing custom upholstery to suit your space just so.
We also take care of the finishing touches, from soft window treatments to the curation of objects and art, creating interiors that feel grounded, expressive, and lived in.
GUIDED INTERIOR SUPPORT
Not every project calls for a full-service approach, and sometimes, a little guidance is all that’s needed.
This service is designed for clients who are comfortable managing their own project but value expert insight along the way. It begins with a thoughtful conversation—where we listen, ask questions, and uncover the areas where support will be most valuable.
From there, we create a tailored design package—whether it’s help selecting finishes, refining spatial flow, or sourcing key pieces. You’ll also have access to our trusted trade suppliers and behind-the-scenes resources, giving you the confidence to move forward with clarity and support.
