Philtower Building

The Philtower Building in Tulsa, Oklahoma, is a historic high-rise complex dating to 1928, built in a blend of Gothic Revival and Art Deco styles. Financed by oil magnate Waite Phillips and designed by Edward Buehler Delk, the building originally served as an office tower. An architectural highlight is the vaulted lobby ceiling, made up of stone rosettes carved in Italy and installed on site by the same craftsmen. The illuminated, pitched tile roof and Phillips's preserved office on the 21st floor underscore the building's historic character. Since 2004, floors 12 through 20 have housed loft apartments, making it the city's first mixed-use high-rise. Today the 24-story structure is a protected landmark in the Oil Capital Historic District.
