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.
Sacha draws on her multidisciplinary design background to create interiors that feel both textural and deeply personal. Whether working on an established built or a full renovation, Sacha brings passion, precision, and a quiet confidence that clients find reassuring and inspiring.
