Notable contemporary residential buildings, restaurants, shops, and office buildings in the city include the Wharf on the Southwest Waterfront, Navy Yard along the Anacostia River, and CityCenterDC in Downtown. The Wharf has seen the construction of several high-rise office and residential buildings overlooking the Potomac River. Additionally, restaurants, bars, and shops have been opened at street level. Many of these buildings have a modern glass exterior and heavy curvature. CityCenterDC is home to Palmer Alley, a pedestrian-only walkway, and houses several apartment buildings, restaurants, and luxury-brand storefronts with streamlined glass and metal facades.
