The South Lake Union Troy Block, which is fully leased by Amazon, recently sold in a transaction that represents the largest asset trade by volume in the history of Seattle. The block is at 300 Boren Ave. N and includes 811,520 SF in two newly constructed office towers.

Ponte Gadea, based in Spain, paid $740M to acquire the office complex, according to a report by The Registry. That works out to $912/SF. The seller is USAA Real Estate and Touchstone.

The towers were completed in 2016 and 2017 and are both LEED-Gold certified. The 12-story tower is 387,476 SF, while the 13-story tower is 415,452 SF. The complex includes 4K SF of ground-floor retail, as well as an underground parking garage with 1,118 stalls.
