Madison Centre

Madison Centre (formerly known as M5 Commerce Centre and 505 Madison) is a 530 ft skyscraper in Downtown Seattle, Washington. It was completed in October 2017 and has 37 floors of office space totaling 746,000 sqft of gross leasable area. It is the thirteenth-tallest building in Seattle. It is located at the intersection of 5th Avenue and Madison Street in Downtown Seattle, adjacent to the Seattle Central Library and William Kenzo Nakamura United States Courthouse.

History
Schnitzer West bought the existing property from the College Club of Seattle in 2007 and hoped to begin construction of a skyscraper as early as 2008. In the meantime, however, the late-2000s recession struck the economy and consequently the fate of many commercial real estate projects came under doubt, including 505 Madison. Further development of the project hinged on securing a sufficient number of preleases by 2009, which did not occur.

In 2012, the project was revived and the developer began seeking permits to start construction. Demolition of the pre-existing buildings on the site began in early September 2014. In February 2016, Cornerstone Real Estate Advisers (now Barings) announced that it would enter a joint venture with Schnitzer West to develop Madison Centre. Construction on the tower topped out in October 2016, and the tower opened for occupancy in October 2017.

Madison Centre was sold in May 2022 to Boston Properties for $730 million.

Tenants
The retail space facing Marion Street was leased to Amazon Go, the second store for the cashier-less convenience store. It opened on August 27, 2018. Hulu signed a major lease for 67,400 sqft within the building in April 2019. Amazon Go closed in June 2023 and is planned to be replaced in 2024 by a small delicatessen and market.
