The joint venture of Rockefeller Group and Stonebridge today joined
Clark Construction and their building crews to celebrate the
topping out of 600 Fifth Street NW, the only new office building
under construction in Washington, D.C. that is set to deliver over
the next two years.
The 400,000-square-foot building, which is 50
percent pre-leased, is taking shape on the site of the former
eight-story Metro headquarters. Stonebridge and Rockefeller Group
completed a 99-year ground lease with Metro in June 2023, and
immediately broke ground on the $375 million project.
Today, crews set the highest piece of steel atop
the building, creating the structure for what will soon be a shared
tenant-amenity space on the 12th floor with soaring 15-foot
ceilings surrounded by outdoor terraces and views of the Capitol.
To reach this milestone, crews placed over 747 tons of structural
repositioning steel, 1,073 tons of overbuild steel atop the
existing structure, and 3,700 cubic yards of concrete, and removed
over 9,800 tons of debris.
The building, 600 Fifth, is one of the only office
buildings in the District to occupy a full city block, which
presented the development team with an opportunity to reimagine the
structure from top to bottom. Beyond the building, the neighborhood
is positioned for an influx of investment and infrastructure
upgrades as part of a $515 million agreement to keep the Washington
Capitals and Wizards at Capital One Arena directly across 6th from
the project through at least 2050.
“We’re thrilled to reach another milestone on this
important project and thank the construction crews and entire
project team for exceptional work,” said Douglas Firstenberg, a
Principal at Stonebridge. “Coming on the heels of the Mayor’s
announcement about plans to invest in the Capital One Arena and
surrounding neighborhood, we are even more thrilled to step closer
to completion.”
Hilary Allard Goldfarb, Senior Managing Director
of Rockefeller Group, said, “This is a project that demonstrates
the transformative power of redevelopment, and with today’s topping
out of 600 Fifth we’re starting to get a glimpse of what the future
of work looks like in downtown D.C.”
In addition to adding four stories, a series of
open-air terraces were designed on every other floor, maximizing
light and air for employees. A new energy-efficient glass curtain
wall will reframe the building, and at ground level a thoughtfully
landscaped public park will offer tenants and visitors additional
outdoor space to enjoy.
“This milestone would not be possible without the
strong partnership between Rockefeller Group, Stonebridge, Clark
and the talented design and trade partners on this project,” said
Terry Simon, division president with Clark Construction. “The trust
and support from these parties, coupled with the hard work and
dedication of the project’s talented craft workers, has enabled
this landmark project to progress safely and successfully.”
In 2023, the international law firm Crowell &
Moring signed a long-term lease for approximately 199,000 square
feet in the building for its D.C. headquarters, becoming the
project’s anchor tenant.
The redesign was planned by the international
design architect Pickard Chilton.
“600 Fifth Street delivers a compelling
next-generation workplace while contributing to the vitality of
this great city,” added Jon Pickard, FAIA, Principal at Pickard
Chilton.
The architect of record is Kendall Heaton
Associates. Clark Construction is the general contractor.
CBRE’s Scott Frankel, Carroll Cavanagh, Dimitri
Hajimihalis, Emily Eppolito and DJ Callahan are the exclusive
leasing agents for 600 Fifth Street NW.
