Trump backs proposed deal to keep TikTok operating in US Several groups were vying to redevelop the 19-story office tower after Ecolab announced in 2015 it would relocate to a building a couple of blocks west. The PAK Properties-led group reached an agreement to buy the building in spring 2017 and the sale closed in June.

“We have a dynamic team that is moving forward with this project step-by-step,” PAK Properties president Rich Pakonen said in a statement. “We have been able to close on the purchase and are now focused on creating what we think can be transformative office space and new energy for downtown Saint Paul.”

Pakonen and his partners plan to rechristen the mid-century office tower Osborn370 and turn it into a hub for tech companies, according to a May report by the Minneapolis-St. Paul Business Journal.
