Waterfront Corporate Campus

Opportunity for Lease


The Southport Office Campus was named a finalist for 2019 Office Development of the Year by NAIOP. 

With an unparalleled central location, accessibility and idyllic setting, Southport is a premier office location.

Situated on the south shore of Lake Washington, Southport is a mixed-use development of 17.1 acres of waterfront property and will include three, 9-story buildings consisting of 712,752 SF of Class "A" office space, together with 664,277 GSF of parking, currently under construction. The offices will join the 383 units of luxury, multi-family housing completed in 2008 and the 347-room Hyatt Regency Lake Washington at Seattle's Southport. Upon completion, the Southport campus will feature four restaurants and additional first floor retail space.



Geographically, the Southport campus is central to the largest high-tech employers in Greater Seattle. Located in Renton, Washington, Southport is strategically positioned between Seattle and the City of Bellevue. The campus is just 8 miles from Sea-Tac International Airport, 9 miles from Boeing Field, and less than 2 miles from Renton Municipal Airport that serves both private jets and seaplanes. Southport is adjacent to I-405 and 10 minutes from Interstate 5 to the West and the I-90 corridor to the North. The state is investing $1.2 billion in the I-405 Master Plan. Phase II is slated to begin in 2019 and will include widening the corridor from Renton to Bellevue adding two lanes, one in each direction. The project will increase capacity and will result in faster travel times.



People from across the area will want to be a part of Southport with its luxury apartments, commercial space, waterfront hotel and conference center, retail shops, and restaurants.


Office tenants will be able to take advantage of the countless sporting and recreational opportunities in the neighboring 57-acre Gene Coulon Memorial Beach Park. The park offers walking trails, tennis and volleyball courts, boat launches and fishing docks, along with a trail lined bird sanctuary. Southport is within walking distance to 32 restaurants and only one-tenth of a mile to The Landing, which is comprised of over 600,000 square feet of entertainment, restaurants, and service and retail space occupied by regional and national tenants. In addition to the commercial aspect, The Landing is a community to over 880 apartment homes.
