The 10-story Logan Building at Fifth Avenue and Union Street was sold Thursday to longtime Seattle developer Unico Properties for $28.2 million, public records show.

The 115,000-square-foot office building was built in 1959 by Harbor Properties, which sold its assets to several investors last year.

Unico also bought the retail units of the mixed-use First & Union residential/retail condo building near the Pike Place Market from Harbor’s successors, paying $9.25 million.
