About South Lake Union
South Lake Union has been the focus of Seattle's most aggressive redevelopment over the last two decades — transformed from a low-rise warehouse district into the headquarters campus for Amazon, plus a major biotech cluster (Fred Hutch, Allen Institute) and high-density residential. The Lake Union waterfront at the north edge anchors the neighborhood.
Residential inventory is overwhelmingly newer mid- and high-rise condos and apartments. Buyers are tech and biotech professionals who want walk-to-work convenience and modern amenities.
