CBRE recently negotiated long-term office leases with major tenants at One South Church, the landmark building in downtown Tucson, Ariz. Global engineering firm HDR has leased 9,659 square feet of space, while Regus, the world’s largest provider of flexible work space, has inked a deal for the entire 12,659-square-foot 12th floor.

Buzz Isaacson with CBRE’s Tucson office represented the landlord, Chicago, IL-based Equity Commonwealth. Kevin Calihan with CBRE’s Phoenix office represented Regus, and Pat Williams with JLL’s Phoenix office represented HDR.

Regus’s lease marks its entrance to the Tucson market. The company has an expansive presence in Phoenix with 21 locations Valley-wide in the best office building in almost every submarket in the metropolitan area.

We’re very excited about the Tucson market,” said Rob Downing, Regional Director of Real Estate for Regus. “The Southwest, and Arizona, in particular, has been a focus for us over the past several quarters. Our Phoenix centers are performing exceptionally well, but our clients were regularly inquiring about locations in Tucson. With the space at One South Church we will finally be able to meet that demand.”

Regus’s new center is currently undergoing tenant improvements to ensure the company will be able to offer its full suite of flexible workspace solutions to the Tucson market. The new work center is slated to open in mid December. Regus is also in the process of identifying a second location in north Tucson with hopes to open that work center sometime in 2015.

HDR relocates to One South Church from their previous location at Williams Centre. The global engineering firm played a major role in bringing the Sun Link Modern Streetcar project to fruition and this move brings the company right onto the streetcar’s 3.9-mile route.

Regus and HDR are excellent examples of companies seeing the value of locating in amenity-rich downtown Tucson,” said CBRE’s Isaacson, who has held the marketing and leasing assignment for One South Church since 1986 and has brokered the sale of the building twice. “There has definitely been a demographic shift toward urban, live-work-play environments. Smart employers recognize that in order to attract and retain top talent they need to locate in areas that offer the “lifestyle” type of work environments employees want.”

Built in 1986, One South Church is Tucson’s premier high-rise office building. Located in the heart of downtown Tucson, the 23-story office tower is located in one of Tucson’s three major employment centers, along with the University of Arizona and Tucson International Airport. Located along the new Sun Link Modern Streetcar route and within minutes of Interstate-10, which boarders the west side of downtown, the property benefits from easy accessibility as well as the numerous retail amenities located in the area.
