After two years and some inevitable development hurdles, Greenbrier Partners LLC’s mixed-use development at 436 S. Front St. is quickly taking shape.

Construction began recently on the more-than-a-century-old warehouse at the corner of South Front Street and East Nettleton Avenue, after partial demolition commenced last July.

The $2.5 million development entails a three-story, 29,000-square-foot building with 5,500 square feet of retail space, 25 apartment units (19 one-bedrooms and six two-bedrooms) and 25 underground parking spaces.

Greenbrier filed a $2.1 million loan through Southern Bancorp Bank in September 2010 to build at the site, which is part of a 10-year payment-in-lieu-of-taxes (PILOT) agreement with the Memphis Center City Revenue Finance Corp.
