Chris Hansen, the man behind the push to build a new NBA-ready arena in Seattle, has led a group of investors to buy the Showbox Sodo property for $8 million.

Hansen has been assembling land in the area for months for a proposed $490 million arena. Hansen has paid more than $48.9 million for the properties.

Hansen’s group now owns about three-quarters of the properties on either side of Occidental Avenue South between South Holgate and South Massachusetts streets.
