Additional details of the Seattle
Sounders FC headquarters project at
Longacres in Renton have dribbled
out since the landmark project was
announced in February, but one
undisclosed detail is who will build it.
On Wednesday, Venture General
Contracting office coordinator
Melinda Ryland said the Seattle
company has been awarded the
contract for the project, whose overall
capital cost is now estimated at $1.5
billion. That’s according to a
document that project developer
Unico Properties submitted to the
city. Earlier, Unico pegged the cost at
over $1 billion.
Unico declined to comment for this story, though in one submittal
said the aim of the project is to “revitalize Boeing’s abandoned
office campus and activate the 115-acre site with updated office,
new housing, retail, dining, recreational facilities and open space
amenities.” Unico late last year paid $100 million for the property.
Other details of the project — now called Seattle Sounders FC
Performance Center at Longacres — have been updated.
Initially, Unico said the transit-oriented redevelopment on the
former Boeing Commercial Airplanes headquarters property would
have up to 3,000 apartment units. But the pre-application states
this has increased to nearly 3,460 units. The project site is next to
Tukwila Station, which is served by commuter rail and bus-rapid
In addition, Unico is evaluating the financial feasibility of building a
parking structure. There are 2,150 parking stalls today, and options
include adding between 3,035 and 5,035 stalls.
In a submittal to the city, Unico said it wants to continue
conversations with the city about the parking garage “because the
garage is the key to securing high-quality tenants, creating the
right ‘feel’ at the site, and providing generous public amenities at
The apartments will be in seven eight-story buildings, according to
project documents, which indicate Seattle-based GGLO is the
architect for the multifamily and new commercial space.
In addition, the existing Longacres office buildings will be
rehabbed along with the potential construction of a new
restaurant/pub and small boat/kayak launch on a lake.
As previously reported, Generator Studio of Kansas City also is
working on the design of the center, which will have four to five
practice fields — two with natural grass and the others with
synthetic turf.
The performance center remains a work in progress. A complete
application has not yet been filed with the city, Renton Senior
Planner Jill Ding wrote in an email.
In one submittal, Unico wrote it anticipates executing a new
development agreement with the city to allow for phased

development of the project. The fields, along with a goal keeper’s
practice facility will be built in one to two phases over the next five
years, according to one document.
Earlier, Unico said construction of the pitches is expected to begin
in early 2023 with the performance center opening in 2024, the
50th year of the soccer club.
