Children's Hospital

Part of a major planned expansion of Minnesota pediatric operating room capacity and private suite offerings, the Minneapolis campus expansion became the first project in the ground of an overall estimated $300,000,000 phased expansion plan. The campus expansion includes a new five-story ambulatory care center with parking ramp, and a nine-story clinic addition to the existing hospital facility.


The Children’s Hospital and Clinics of Minnesota Minneapolis campus was constructed in two phases. Empirehouse was contracted to provide the exterior curtainwall and composite metal-panel system cladding for the new five-story building and the nine-story clinic expansion.

The new building’s curved façade connects to the tower expansion by a skyway which is composed of a monumental compound curved, dual-cantilevered structural silicone-glazed cladding system.

Empirehouse provided both the aluminum panel and curtainwall systems which maximized the envelope product integration and efficiency of the building envelope installation.


Empirehouse selected façade and functional components to integrate within the curtainwall system. This allowed for easy access to windows from the inside or the outside of the enclosure. Vapor barrier components were installed to ensure that the patient environment was free of water infiltration.

Glass, glazing and fabrication scope:

  • Glass type: Multiple glass substrates, coatings and frits were used for this project.
  • Metal: EFCO Corporation fully captured and structural silicone glazed curtainwall framing, custom painted stone grey finish
  • Additional scope: Empirehouse provided mechanical louvers, revolving door systems, automatic bi-parting door systems, automatic bi-folding door systems, and oversized bi-folding traffic doors.
