Located near the Rockville Metro Station and Maryland Route 355 in downtown Rockville, a historic Maryland city that was beginning to recognize the advantages of the one-seat ride to downtown D.C., the property was mostly occupied by a dilapidated shopping mall, which Essex Capital razed. The company then created and executed the long-term master plan for the property, a $300 million development with 1.3 million planned square feet of office space, housing, retail, and restaurants. Essex Capital also enlisted the global architecture firm HOK to fine-tune the project's "town square" aesthetic.

The redevelopment of Rockville Town Center included many complex and ultimately successful development initiatives, including a new subterranean 13-screen movie theater and, at 255 Rockville Pike, the conversion of an empty department store shell into a 200,000 square foot office building that became the county's headquarters. Essex Capital also planned and built several "development pads," individual sites primed for new construction that were then resold to other developers, or held on to as long-term investments.

Another major component of the project involved replacing the failed mall superblock with a traditional block and grid system, to which all new buildings were adapted. Working with local, county, and state government officials, Essex Capital was also responsible for building the project’s infrastructure, including roads, sidewalks, sewers, parking garages, plazas and public green space. Space was also provided for the town's library and arts center, creating a lasting bond with the people of Montgomery County.
