Who we are
Our Philosophy
At Opal & Oak, we believe that great design is a harmonious blend of aesthetics and functionality. Our mission is to craft spaces that not only look stunning but also enhance the lives of those who inhabit them.
Our Approach
We take the time to understand your vision, preferences, and lifestyle. This collaborative process ensures that the final design is a true reflection of you.
Opal & Oak is founded by Sacha Wark-de Boer, a creative force with a background in fashion and graphic design. Born in the Netherlands and now based in Australia, Sacha brings a distinctly European sensibility to her work, balancing refined aesthetics with warmth, and blending contemporary edge with timeless elegance. Her Dutch background instilled a deep appreciation for form, function, and beauty, which is evident in every space she curates.
With an intuitive eye for colour, composition, and texture, Sacha draws on her multidisciplinary design background to create interiors that feel both elevated and deeply personal. Her approach is grounded in collaboration, thoughtful curation, and a strong belief that great design enhances daily living.
Whether working on a simple styling refresh or a full interior transformation, Sacha brings passion, precision, and a quiet confidence that clients find reassuring and inspiring.
