Valeria Coster
Valeria Coster is a Brazilian-born architect and founder of Valeria Design Studio, a practice rooted in empathy, human connection, and respect for nature. Educated at the Faculdade de Belas Artes de São Paulo, she began her career in Brazil before moving to the United States in 2003. Her multicultural journey and life-long fascination with people’s relationship to space define her philosophy: design is not about imposing a style, but about listening deeply and creating environments that reflect the essence of those who inhabit them.
Since arriving in the U.S., Valeria has nurtured a long-standing creative partnership with artist Jennifer Radoci, with whom she collaborates on projects that merge art and design into poetic, human-centered spaces. Together, they curate interiors that embody their shared values: love for people, reverence for nature, and the joy of creation.

Studio ŪMA
Studio ŪMA, founded by Michelle Song and Amber Pan, draws deeply from Eastern philosophy and the aesthetics of imperfect beauty. Their work embraces time’s subtle marks oxidised metals, weathered wood, softened edges as signs of life rather than decay.
Each element is quiet but intentional, layered with contrast: stillness and movement, weight and air, the seen and the suggested. Whether it be through the convergence of different textures, or the artful juxtaposition of mid-century furniture, entwined tree vine, and tribal utensils sourced from around the globe, their designs embody a harmonious fusion of elements coming from various cultures and origins.
Their services include architectural planning, listed building consent consultancy, planning application consultancy, remodeling, interior architecture design, and art advisory.
