SOUTHLAKE, TX-After nearly 15 months of talks, Fidelity Investments has inked a 10-year lease for a 101,934-sf class A office building in Cedar Ridge Office Park. It's the third major real estate deal this year in the metroplex for the Boston-based financial giant.

A Fidelity spokesman says the three-story shell, which just delivered last month at 1150 N. Carroll Ave., builds in “a little bit of flexibility and options” to its expansion in Dallas/Fort Worth, where a $200-million, 600,000-sf office building is under construction at its Westlake campus in northeast Tarrant County. The Westlake building, which broke ground last month, is slated to come on line in 2009.

Fidelity has just started the Cedar Ridge finish-out. The building will be ready to occupy in February or March. It's unclear if Fidelity's existing teams in Southlake will be uprooted to Cedar Ridge or the space will hold Westlake workers being relocated due to the construction at the seven-year-old campus. Fidelity's Southlake sites consist of a retail site at 1256 Main St., one of four in North Texas, and a data center at 1576 E. Southlake Blvd.
