Mustard&Linen ‘house style’ and design philosophy
At Mustard & Linen, we are storytellers, bringing each brand’s unique narrative to life through design. We collaborate closely with clients and architects, turning their vision into reality with a deep intuition for their needs. We always think of the customer journey and how the space is perceived. Our diverse backgrounds and collective strengths allow us to create cohesive, beautiful experiences that are both minimal and soulful, blending monumentality with intricate detail.
Our signature style fuses sculptural gestures, bold proportions, and layered textures, resulting in spaces that are timeless, dynamic, and purposefully designed. By combining functionality with aesthetic beauty, we craft environments that feel custom-tailored and leave a lasting impact.
What empowers Mustard&Linen?
Our team is empowered by a shared commitment to creativity, collaboration, and a deep understanding of design. Trust and respect are at the core of everything we do, allowing us the freedom to experiment and grow together. As an international, close-knit team, we celebrate individuality while working collectively to bring fresh ideas to life. Our diverse backgrounds enrich every project, and our focus on continuous learning enables us to take on exciting, large-scale challenges. Together, we create meaningful, impactful designs that resonate with those who experience them.
