Dallas and Oklahoma investors joint venture on Allen office buy Steve Brown, The Dallas Morning News Investors have snapped up a high-profile Allen office project. Dallas-based Pillar Commercial teamed up with Oklahoma-based Hall Capital to purchase the One Bethany East office building, which is located in the Watters Creek development near U.S. Highway 75. Built in 2018, the five-story, 120,000-square-foot office building has been up for sale since last fall. It’s next to Allen’s new Watters Creek convention center. “One Bethany East is a premier Class A office project with strong tenancy,” Manny Ybarra, Founder and CEO of Pillar Commercial, said in a statement. “It is representative of the City of Allen’s impressive work to grow its corporate tax base with high-quality office and mixed-use developments.”
