Halle Building Group of Apex has purchased 300 acres of undeveloped land at the edge of Research Triangle Park on Ellis Road with plans to begin a multiphase, multimillion dollar development of apartment, residential and commercial construction. Construction could begin as early as March 2015 on phase I, a 336-unit apartment community on the southern end of the property at the intersection of N.C. 147/Durham Freeway and Ellis Road. The development could also include about 800 single family homes and townhouses. Preliminary plans for a 63-acre site zoned for retail and commercial development is also being marketed for a possible hotel, convenience store and restaurant locations. A future phase could also add a second large apartment complex on the northern end of the property, enough to support about 400 more apartment units.
