Southport (Renton, Washington)

Southport is a 2.4 million square-foot mixed-use development,[1] located on 32.2 acres of property along Lake Washington in Renton, Washington.[2] Development began in 1999, when Seco Development's CEO Michael Christ purchased the Shuffleton steam plant from Puget Sound Energy for $7 million.[3] Initial plans were to create a mixed-use complex including between five and eight buildings, between 543 and 581 residential units, from 500,000 to 750,000 square feet of office space, and 38,000 square feet of retail space.[4] The Shuffleton plant was demolished in 2001, and construction on the residential phase of Southport began later that year.[5] An additional 7.7 acres was purchased from Puget Sound Energy for the purpose of expansion in 2019.[6]

Between 2002 and 2008, the complex opened 383 residential apartment units.[3] By 2015 construction had begun on a 347-room Hyatt Regency of 12 stories in height, in addition to a 43,000 square foot convention center.[1] Ground was broken on the development of the complex’s office space in 2016, designed by ZGF Architects.[7] The hotel and conference center opened in 2017.[8] As of 2019 the complex included 712,752 square feet of office space[9] across three office buildings.[1] The complex also includes 30,000 square feet in retail space.[10]

Seco plans to run ferry routes directly between Southport and other parts of the region, including South Lake Union in Seattle.[10] The complex also includes a six-story parking garage[3] and a private yacht dock.[11]
