Who We Are

At Abacus Architects, we believe architecture is about more than buildings—it’s about people. That’s why we practice Relational Architecture, an approach that prioritizes collaboration, connection, and community. Founded in 2003, we are a full-service firm with offices in Sheboygan, Manitowoc, and Milwaukee, Wisconsin, offering expertise in architecture, interior design, and civil engineering. Our diverse portfolio includes schools, healthcare facilities, commercial spaces, civic buildings, and community projects—each designed to enrich lives and strengthen the places we call home.
