Madison Centre, formerly known as M5 Commerce Centre, is a 530-foot (160 m) tall skyscraper planned for the Downtown district in Seattle, Washington. It is scheduled to be completed in 2015 and have 36 floors. Upon its completion, it would be one of the tallest buildings in Seattle.
Schnitzer West bought the existing property at the site 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.
