1400's Redevelopment

Located in Rosslyn, Virginia, just minutes from downtown Washington, D.C., 1400 Key Boulevard and 1401 Wilson Boulevard comprise a 2.1-acre urban infill site in the heart of Arlington’s Rosslyn submarket.

‍

The Arlington County Board originally approved redevelopment plans in 2014 to replace two existing 12-story office buildings with a residential tower at 1400 Key and an office tower at 1401 Wilson. In August 2025, Monday Properties submitted a revised vision for the site, transforming the project into two high-rise residential towers. The new proposal preserves the benefits of the original approval while introducing enhancements that respond to evolving market demands.

‍

The towers are designed by Shalom Baranes Associates, a leading Washington, D.C.–based architecture firm, and the updated proposal is now under review by Arlington County and open for public comment.
