Check out the spectacular views — and the inside — of Rosslyn's new observation deck

From the 12,000-square-foot deck on the 31st and 32nd floors, one could take in 360-degree views and the entire layout of the nation's capital.

The Washington Monument and U.S. Capitol building stood tall through the cloudy skies. The faint outline of Tysons Corner seemed to just appear. Looking though a shroud of clouds, there was Pentagon City.

One could only imagine what the views would be like on a clear day. Local residents and tourists will be able to discover the panoramic views for themselves come July, when the space is expected to open the public.

The deck is significant not only because it will offer views unlike any other available in D.C. but also because it is one of the most important features of Central Place, a two-tower project featuring 377 apartments, roughly 500,000 square feet of office, retail and a large hardscaped plaza above the Rosslyn Metro station. It's part of a larger vision by building owner JBG Smith Properties (NYSE: JBGS) and Arlington County to create a public amenity, said Matt Ginivan, senior vice president with JBG.

"Part of the idea of how that building could contribute to Rosslyn and Arlington as a whole was to make it more than just a building and share some of those views with the public, and have that serve as a public amenity and an anchor for transforming Rosslyn," Ginivan said. "There are going to be people there not just 9 to 5 but also on the weekends."
