“Try to be a rainbow in someone’s cloud.” The Children’s Hospital of Orange County (CHOC) embodies this quote from Maya Angelou. From the outside, as seen in the evening, the building is illuminated with a rainbow of color on the vertical circulation tower, shining like a beacon of hope throughout the community. When CHOC opened in 2007, it was the only dedicated pediatric facility in the region, providing surgery, imaging, emergency and clinical lab services, acute care and intensive care inpatient beds, and amenity areas for patients, families and staff. CHOC named the new addition to the hospital The Bill Holmes Tower, after the self-made pool entrepreneur who started from very humble beginnings and donated $27 million to fund the construction. PRISM worked with FKP Architects (now part of CannonDesign) to emulate the hospital’s striking colorful design in several exterior and interior renderings.
