One North Central Office Tower

One North Central, was previously known as the Phelps Dodge Corporation Headquarters. Phelps Dodge was a global leader in the mining and manufacturing industries, and they sought a premier downtown location in an office tower. Ryan working with Phelps Dodge, the City of Phoenix and the design consultants developed a 20-story, class “A” headquarters building.

Located on a city-owned site in the heart of Phoenix, the building offers large floor plates (up to 30,900 square feet) with minimal interior columns for interior design flexibility. The 4-level garage accommodates up to 1,000 cars. The exterior base of the building is Arizona sandstone and granite. The upper floors are sheathed in copper-tinted glass curtain wall. The award-winning tower presents a sweeping curve along its north side providing panoramic views in the distance.
