At the top of the list will be finding a tenant or tenants to fill 104,000 sf of premier office space that is now largely vacant as a result of Nokia's move to its new nearby location, Kevin, McGlaun, Cousins Stone's vice president of business development, tells GlobeSt.com. In all, there is 109,000 sf available, but the Nokia space encompasses four floors in the 10-story, 256,000-sf, class-A structure. With Nokia's exit, Ryan Partnership is now the building's lead tenant.

The three-year-old building is located in the 72-acre Sierra Office Park at the intersection of Texas 161 and MacArthur Boulevard. The space, says McGlaun, "is ready to go." It is commanding an average asking price of $24 to $24.50 per sf.

Cousins Stone's senior vice president Mark Dickenson, vice president Bill Lokey and leasing associate Matt Schendle will market and lease the property.

"It is one of the finest office properties to be built in Las Colinas in the last five years," says Dary Stone, Cousins Stone's president. The pact expands the relationship between Cousins Stone and Northwestern Mutual, he says.

Cousins Stone is now overseeing a six-million sf portfolio of class-A office properties. In addition to 6565 MacArthur at Sierra, the portfolio includes The Towers at Williams Square, 1700 Pacific, Millennium Center, Spectrum Center, Beal Bank Center and The Points at Waterview, all situated in the Dallas-Ft. Worth metroplex. It also leases and manages Austin's Research Park Plaza. Cousins Stone, a venture of Atlanta-based Cousins Properties Inc., is the development manager for Las Colinas, the tony 12,000-acre, master-planned business and residential community adjacent to the DFW International Airport.
