Events D.C., the quasi-public agency that operates the Walter E. Washington Convention Center, is moving forward to break down the imposing walls that dominate the streets and sidewalks on the massive building’s exterior.

The city’s conventions and sports authority wants to add a rooftop lounge, install brightly-lit retail kiosks in existing alcoves and remove some of the concrete structure around the entrance to the Mount Vernon Square Metro station to make it more lively.

The agency been working on ways to activate the streets around the convention center for the past two years, installing several new restaurant and retail tenants in the previously vacant retail spaces. The 2.3 million-square-foot, three-block building was completed in 2003, and Events D.C. says the area suffers from an “anemic pedestrian energy.”
