At the July 22, 2024, regular meeting, the Arlington County Board took action to close the Observation Deck at 1201 Wilson Blvd. in Rosslyn.
The Observation Deck will officially close on July 31, 2024. This closure marks the acceleration of a major reinvestment in Rosslyn Gateway Park during a transformative period for the Rosslyn community.
CoStar Group, a leading global provider of online real estate marketplaces, information, and analytics, purchased 1201 Wilson Blvd., a 560,000-square-foot office building known as Central Place Tower, in February 2024.
CoStar Group Funds Significant Investment in Rosslyn Gateway Park
As part of the economic development deal, CoStar Group will pay Arlington $13,951,900 to significantly expedite the redevelopment of Rosslyn’s Gateway Park, accelerating its completion by nearly a decade. This investment will transform Gateway Park into a vibrant, multifunctional public space and world-class destination that is a central anchor for the Rosslyn community.
The redevelopment of Gateway Park, led by Field Operations, the same group of designers responsible for Met Park, will introduce new amenities, green spaces and recreational opportunities, creating a welcoming environment for all.
A New Outlook for Rosslyn
In the CoStar Group deal, Arlington County recognized a unique and impactful opportunity to marry Rosslyn’s community benefits with significant economic gains. CoStar Group initially considered Arlington due to its prime location and premier trophy building in the heart of Rosslyn.
Throughout the site selection process, CoStar Group discovered more about Rosslyn’s business HQ-friendly environment as well as Arlington’s highly skilled workforce, accessibility to two international airports, strong Metro system, high quality of life and dynamic urban centers — key factors that ultimately influenced the company’s decision to purchase the building.
