In the 1990s, Stella began making free-standing sculpture for public spaces and developing architectural projects. In 1993, for example, he created the entire decorative scheme for Toronto’s Princess of Wales Theatre, which includes a 10,000-square-foot mural. His 1993 proposal for a Kunsthalle and garden in Dresden did not come to fruition. In 1997, he painted and oversaw the installation of the 5,000-square-foot "Stella Project" which serves as the centerpiece of the theater and lobby of the Moores Opera House located at the Rebecca and John J. Moores School of Music on the campus of the University of Houston, in Houston, TX. His aluminum bandshell, inspired by a folding hat from Brazil, was built in downtown Miami in 2001; a monumental Stella sculpture was installed outside the National Gallery of Art in Washington, D.C.
