A Rooftop Pool Deck with a Monumental View

Quiet Elevation Above the Mall

At Annex on 12th, the pool deck frames the city in a way that few other buildings in DC can match. The water meets the edge with barely a seam, drawing your eyes toward the Washington Monument and the rooftops of downtown DC. From this height, you can take in the full sweep of the National Mall, watch the sunlight move across the Potomac, and even glimpse the towers of Arlington.

Finished in large-format stone tile, this scenic space is bordered by glass railings that keep the sightlines open. Tailored chaise lounges line one side of the swiming pool, inviting you to recline and relax. To the left, built-in bench seating with low tables provides additional room for gathering.

With large glass doors that open directly to the lap pool area, the nearby indoor rooftop lounge combines a fireside seating room, bar-height dining space, and a full demonstration kitchen for dining and entertaining. It's a seamless indoor-outdoor space, all with incredible views of Southwest DC and beyond.
