vacant for a number of years
before Amazon.com occupied
a good portion of it.

SEATTLE-CPT West 8th LLC, an affiliate of Boston-based AEW Capital Management, has purchased the 28-story West 8th office tower downtown for approximately $278.7 million from locally based Touchstone Corp. and Prudential Real Estate Investors.

Touchstone had developed the office building, located at Virginia St. and Eighth Ave., in 2009, and had co-owned it with PREI before putting it up for sale earlier this fall. The property had stood primarily vacant for a number of years before Amazon.com Inc. became a tenant; the mega-retailer now occupies most of the space in the tower.

As GlobeSt.com previously reported, in October Amazon.com announced that it would purchase the 11-building headquarters campus here it had been leasing from Vulcan Real Estate for a price of $1.16 billion, industry sources reported at the time. GlobeSt.com had previously reported in September that Vulcan had put the properties housing the online goliath’s global headquarters on the sale block, and while the parties involved were not able to reveal a list price for the campus to GlobeSt.com, at the time industry sources unrelated to the deal said the aggregate price for the properties was expected to be greater than $1 billion.
