Shade pavilion, Stuart Pharmaceutical Company Office and Plant, 3360 E. Foothill Boulevard, Pasadena, CA 1958. Listed in the National Register of Historic Places (at the state-wide level of significance) in 1997. Edward Durell Stone, architect; Thomas Church, landscape architect. Set in a sunken courtyard, the shade pavilion is adjacent to an elliptical swimming pool and bath house designed for the employees of the Stuart Company. The steel-framed structure, originally painted gold, has a folded plywood roof. It is now in deteriorated condition. It may, however, be rehabilitated as part of a proposal for new development on the site.

The Stuart Company building is notable for the decorative screen wall, which became a signature feature of Stone's work in the late 1950s. The shade pavilion is a rare surviving artifact of Space-Age design with associations with two famous designers: Stone and Church.
