Civic Buildings
RATIO excels in navigating the complexities of community-based projects. We are committed to the greater good, overcoming funding challenges, administration changes, and public/private partnership intricacies. Our inclusive approach builds consensus, evaluates needs, and solves problems. We immerse ourselves in each community, bringing creativity and authenticity to the design process.









Public Libraries
The public library has evolved into a community landmark with makerspaces and kitchens for cooking classes, reflecting the values and vitality of its people. Modern library design incorporates expertise from various fields like education, hospitality, and STEM. Our interdisciplinary approach leverages these to enhance and sustain communities for years to come.










Cultural Facilities
Our cultural practice designs uplifting public spaces that unite us, inspire appreciation for art and history, and capture our imagination. RATIO’s inclusive engagement builds consensus, and our interdisciplinary approach brings museums, theaters, and civic spaces to life, creating authentic places where visitors feel connected and inspired.


Shaped by the site’s natural slope, the venue optimizes acoustics and views while its bold roof and pedestrian connections establish it as a cultural anchor.








Recreation + Community Centers
Recreation centers are vital for community building, sharing cultural heritage, promoting healthy lifestyles, and fostering friendships. We design spaces where people of all ages and backgrounds can come together. From large complexes to small impactful spaces, our designs create sustainable, comfortable environments that enhance community quality of life.
