Skymark Reston Town Center, the D.C. region's tallest residential building, tops out

Clark Construction on Thursday topped out on the construction of Skymark Reston Town Center, what is billed as the tallest mixed-use residential tower in Greater Washington.

The 40-story high-rise will include 464 residential units on top of a four-story base that will include ground-floor retail, 44 loft-style units and 80,000 square feet of office space. Clark says the building is 470 feet, which would make it the same height as Tysons’ Capital One Tower, the tallest building in Greater Washington. The building was slated to rise 432 feet high, according to preliminary documents outlining Fairfax County’s plans for the Reston Town Center expansion.

Boston Properties Inc. (NYSE: BXP) is the developer; SCB is the architect.

Bethesda-based Clark said 46,000 cubic yards of concrete have been placed by D.C.’s Baker Concrete Construction to shape the Skymark tower, which will total 1.3 million square feet.

Clark has already completed two office buildings at Reston Town Center, 1950 and 2000 Opportunity Way, that were also developed by Boston Properties.

Skymark also includes five levels of parking, both above and below grade. Clark said workers will now turn to completing the building envelope and interior construction. Substantial delivery of Skymark is scheduled for early 2025.

Capital One Tower, the headquarters for credit card giant Capital One Financial Corp. (NYSE: COF), is the region’s tallest building and The Washington Monument, at 555 feet, is the region’s tallest structure. Carr’s The Wilson office building in Bethesda is suburban Maryland’s tallest building at 341 feet. Clark also constructed that tower.
