Work is ready to start on the first major commercial structure at Nexton, a 4,500-acre master-planned community in Summerville.

MeadWestvaco Corp.’s Community Development and Land Management units and The Rockefeller Group plan to break ground Wednesday on a modern, energy-efficient 100,000-square-foot office building off U.S. Highway 17A near Interstate 26.

A portion of the office space will house MWV Community Development and Land Management division. The developers are seeking tenant for the rest of the space

Nexton was formerly called The Parks of Berkeley. The tract of forestland that runs westbound along I-26 from Highway 17A to the Jedburg exit. MeadWestvaco envisions Nexton as a decades-long venture that will combine detached homes, apartments, offices, hotels, shopping, restaurants, schools, parks, bike paths, hiking trails, light industrial space and an interconnected road system.
