Studio Mutual Spaces is a design practice built on the belief that meaningful environments arise from mutual relationships, between people, nature, materials, and the built environment. Our name reflects this core principle: spaces are never created alone. They emerge through exchange, reciprocity, and the interplay of many influences, from cultural memory to ecological context to daily human rituals.
Working across architecture, interiors, landscape, urban strategies, and crafted objects, we approach design as an interconnected ecosystem rather than separate disciplines. This perspective allows us to shape environments that are thoughtful, cohesive, and rooted in place.
Material responsibility sits at the center of our work. We prioritize healthy, sustainable materials and an aesthetic that balances contemporary clarity with cultural depth. Our process is human-centered and research-driven, with a focus on creating spaces that feel emotionally resonant and support well-being.
Above all, we design mutual spaces: environments that cultivate connection — to each other, to our surroundings, and to the stories that define who we are.

MSc Architecture & Environment · BSc Architecture · LEED Green Associate
With years of experience designing exhibitions and immersive environments for visitors, I have developed a deep understanding of how architecture and design can engage and connect people. Over more than a decade of practice across Europe, Asia, and the United States, I have designed exhibitions, architectural spaces, and multidisciplinary environments for institutions and studios including the Carnegie Museum of Art, Volkswagen, GSM Project, deWinder, Neo Studio Architects, Iglhaut von Grote, and NAU Architects. At the Carnegie Museum of Art, I contributed to the 58th Carnegie International, collaborating with over 100 artists and global partners.
I founded Studio Mutual Spaces to explore how architecture can deepen the relationship between people, nature, and the built environment. My background in Architecture & Environment, combined with my LEED training and extensive additional studies in material health and sustainable building practices, has shaped a design approach grounded in material responsibility, ecological awareness, and human-centered thinking.
My practice bridges architecture, interiors, exhibition design, and crafted objects, guided by a commitment to healthier materials and thoughtful, place-conscious design. I believe that impactful environments emerge through mutual relationships — between people, stories, and the spaces they inhabit.
Let’s create a mutual space together, where your vision and our design philosophy come together in a shared, thoughtful design journey.
