Swedish Health System is set to break ground its largest project in its more than 100-year history, reports the Puget Sound Business Journal.

The $1.3-billion North Tower project, planned at the corner of Marion Street and Minor Avenue at Swedish Health's First Hill campus, has been in the works since 2015. The acute care facility, combined with a second outpatient and imaging building with offices, would double the footprint of the campus from 1.5 million to 3.15 million square feet.

The 12-story building, which is being designed by Perkins&Will, is poised for completion in Fall 2027. Inside, plans call for a 31-room emergency department and eight rooms for behavioral healthcare. It will initially debut with 72 beds, with 108 more planned.

Other members of the project team for the North Tower include general contractor Mortenson, HVAC contractor MacDonald-Miller Facilities Solutions, and VECA Electric & Technologies.

Swedish health will later seek a development partner for the aforementioned second project - called Block 95 - which would consist of 900,000 square feet of space at the northeast corner of Boren Avenue and Cherry Street.
