What's Hot: 831 Units, Grocery Store, and Pedestrian Corridor: Rosslyn's 1401 Wilson Heads For Review
1400 Key Boulevard
Rosslyn
Monday Properties has ambitious plan to transform a pair of vacant 1960s office buildings in Rosslyn into a major mixed-use development. The latest iteration of the project — two 27-story residential towers with 831 total apartments at 1401 Wilson Boulevard and 1400 Key Boulevard — goes before Arlington County's Site Plan Review Committee (SPRC) later this week, with discussions focused on parking, transportation, open space, and sustainability. The broad strokes of the project remain consistent with what UrbanTurf first reported last August: a 300-foot Wilson Tower (South) with 506 units and roughly 11,900 square feet of ground-floor retail, and a 300-foot Key Tower (North) with 325 units anchored by a 17,004-square-foot grocery store. The unit mix skews heavily toward one-bedrooms, which make up just over 56% of the 831 total apartments, with two-bedrooms accounting for another 32%. Monday Properties is requesting a reduced residential parking ratio of 0.63 spaces per unit rather than the one-to-one ratio,
