Comstock Partners LC, Reston, Va., is preparing to break ground on various projects on land it holds near Metro stations in Reston and Ashburn, Va., according to the Washington Business Journal.

The company is planning two mixed-use developments—Reston Station and Loudon Station—which would involve 5.1 million square feet of residential, office, retail and hotel space.

Comstock plans to break ground on the 1.3 million-square-foot Reston Station project in April. The first phase includes a 360-unit apartment building, seven-story underground garage and 70,000 square feet of retail space. The second phase will involve at least one office building, residential buildings and possibly a hotel.

The plan calls for 19.5 percent affordable housing and work force housing units.

The company also plans to break ground on its 3.8 million-square-foot Loudon Station in Ashburn. The project will involve about 1,800 apartments, 2 million square feet of office space, and hotel and entertainment space. The first phase will include 357 rental units and 100,000 square feet of retail.
