Treasure Island Center

Project Details

Owner: St. Paul Port Authority and Hempel

General Contractor:
RJM Construction

Architect: Collaborative Design Group

Location: Minneapolis, MN

Size: 540,000 SF

Services: Design-Assist, Fabrication, Installation

The former Macy’s building in downtown St. Paul has been transformed into Treasure Island Center—home to the Minnesota Wild’s rooftop practice facility, TRIA Rink. This dramatic redevelopment features four stories of glass curtainwall and a fifth-floor ice arena, all executed with creative problem-solving and high-performance systems. Empirehouse partnered with RJM Construction and Collaborative Design Group to deliver nearly 20,000 square feet of glass, including 6,500 square feet of SageGlass electrochromatic glazing that tints automatically to reduce glare and solar heat gain.

Empirehouse also provided design-assist expertise to overcome complex engineering challenges. To accommodate six inches of roof truss deflection above the rink, the team developed a flexible yet watertight Tremco silicone sheet detail protected with custom break metal. A reinforced operable glass window wall was also engineered with steel supports to meet structural and aesthetic goals—ensuring long-term performance and a clean architectural finish.

Scope:

  • Installed three floors of Oldcastle Reliance 7-1/2″ deep fully captured curtainwall (approx. 13,500 SF of 1″ blue-tinted insulating glass with low-e coating)

  • Glazed 6,500 SF of SageGlass electrochromatic smart glass

  • Approx. 200 LF of custom post-mounted Trex guardrail system with 5/16″ clear tempered laminated glass

  • Approx. 500 SF of Oldcastle FG3000T aluminum storefront framing with 1″ blue Pacifica tinted low-e glass (exterior) and 1/4″ clear tempered glass (interior)

  • Aluminum swinging doors with 1″ blue Pacifica tinted insulated low-e glass

  • Three fully automatic bi-parting sliding door assemblies with various insulated or tempered glass types

  • Approx. 50 LF of plexiglass dividers with aluminum sill channels for observation booth

  • Interior borrowed lites and fire-rated glazing systems

Mother-Baby Program

Project Details

General Contractor:
Knutson Construction

Architect: HDR Architects

Location: Minneapolis, MN

Size: 23,000 SF Remodel, 96,000 SF Addition

Services: Design-Assist, Fabrication, Installation

In response to the growing need for a specialized space where mothers and newborns can receive the highest level of care together, Allina Health and Children’s Minnesota partnered to create The Mother Baby Center at Abbott Northwestern Hospital.

Empirehouse joined Knutson Construction Services to furnish and install more than 65,000 square feet of custom curtainwall and aluminum composite panel systems. The project featured convex and concave curved, dual-cantilevered aluminum pressure-wall framing paired with ACM wall cladding, offering high thermal performance through innovative fiberglass pressure-bar assemblies.

Installation required precision, safety, and meticulous planning due to the tight urban site and fast-paced schedule. The most complex element—a skyway spanning the busy 26th and Chicago Avenues—was successfully completed with minimal disruption, thanks to Empirehouse’s detailed logistical coordination.

Scope:

  • 65,000+ SF of architectural glass and aluminum composite panel systems

  • Custom convex and concave curved aluminum pressure-wall framing

  • Dual-cantilevered structural framing

  • ACM (Aluminum Composite Material) cladding system

  • Fiberglass pressure-bar assemblies for enhanced thermal performance
