At Studio (SUM)Thing, we believe design is more than what meets the eye—it's a catalyst for connection, a tool for transformation, and a foundation for legacy. Founded by designer Manori SUManasinghe, our studio is rooted in the idea that thoughtful design can uplift individuals, reflect shared values, and enrich entire communities.

​

We specialize in designing spaces that bring together delight, intention, and real-world impact. Whether it’s a high-end home, a wellness retreat, a neighborhood business, or a public activation, our work is shaped by a deep understanding of place, people, and purpose.

​

With each project, we bring empathy, curiosity, and clarity to the table—guiding clients through a collaborative process that honors both personal vision and collective good. From the smallest detail to the big-picture vision, we’re here to help you unlock the potential of your space and create something truly timeless.

​

Let’s build spaces that spark delight, foster connection, and reflect what matters most!
