KOIN Center, acquired by Property Group Partners in 1993, is a mixed-use building covering an entire block in the heart of the central business district. The exterior combines natural limestone and brick, trimmed in marble with grey-tinted reflective glass windows. The galvanized steel crown, with stainless steel edges and color-coated sky blue, is a focal point of Portland’s skyline. Interior finishes include Italian perlato marble floors and walls, anodized aluminum doors and custom-designed chandeliers.

KOIN Center has 23,000 square feet of retail and entertainment space on the first three levels; 324,000 square feet of office space on Floors 4 through 19 and 44 condominiums on the uppermost 11 floors. The studios and broadcast facilities of the local CBS affiliate, KOIN-TV, are located in approximately 68,000 square feet below grade.
