WASHINGTON, D.C. – March 9, 2026 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, announces that Watergate 600, one of Washington, D.C.’s most iconic and architecturally significant office properties, has a 125,000-square-foot top-block office space available.
The fully renovated landmark asset features premier top-block availability, a wraparound private terrace on the 7th floor, and views of the Potomac River and multiple Washington, D.C., monuments. The reintroduction of Watergate 600 comes as tenants continue to prioritize high-quality office environments and enhanced occupier experiences.
Located at 600 New Hampshire Avenue NW in Washington, D.C.’s West End, Watergate 600 is a 12-story, 316,000-square-foot Class A office building offering a distinctive combination of legacy architecture and modernized infrastructure. Recent capital improvements include redesigned multi-tenant common areas, an enhanced building lobby and entrance sequence by award-winning architect LSM, a rooftop terrace, state-of-the-art conferencing and event facilities, a modern fitness center, and comprehensive building upgrades, such as new windows and elevators. These improvements align the historic property with the expectations of today’s office tenants while preserving its timeless character.
The property offers a rare waterfront setting within Washington, D.C.’s urban core, highlighted by approximately 125,000 square feet of office space across four contiguous upper floors. The availability features expansive river views, sightlines to several of the city’s most recognized monuments, and a private terrace designed to support collaboration, meetings, and client-facing events.
“Watergate 600 offers a rare opportunity to lease a premier, contiguous top-block in one of Washington’s most established submarkets,” said Matt Pacinelli, Managing Director at Stream. “Opportunities of this scale—125,000 square feet with monument and Potomac River views and a private terrace—are exceptionally limited in the West End. Combined with the building’s recent capital improvements, this availability offers tenants the ability to secure a distinctive presence within a landmark property.”
Within walking distance of Georgetown, Foggy Bottom, and The Kennedy Center, Watergate 600 provides convenient access to dining, hospitality, and transit options. Its West End location continues to attract legal, financial, advocacy, and professional services firms seeking a prestigious and accessible address.
Stream’s Advisory team, led by Pacinelli, Managing Director Charlie Smiroldo, and Associate Lukas Stanat, represented the new ownership in the acquisition, while JLL represented the seller. Stream will continue to serve as the exclusive leasing representative and property management company for the property.
