D Real Estate Daily: A year after it opened to much fanfare, Google’s 445,780-square-foot Motorola Mobility smartphone manufacturing plant at Hillwood’s AllianceTexas development in North Fort Worth will be shuttered by the end of the year. At last year’s facility opening event, Hillwood’s chairman, Ross Perot Jr., joined Google chairman Eric Schmidt, Texas Gov. Rick Perry, and Dallas Mavericks owner Mark Cuban. Motorola and its contract manufacturer, Flextronics, took occupancy of a former Nokia plant at Alliance that had sat empty since 2007. The corridor began seeing a brisk uptick in activity last year, prompting Hillwood to move forward with about 1.3 million square feet of speculative space, on top of a 1.2 million-square-foot build-to-suit for LG Electronics. Executives at Hillwood were not immediately available to comment for this story. See full story.
