Located in the heart of Downtown East, 4th and Park is a 25-story multi-family residential tower that brings modern design and high-performance glazing to the Minneapolis skyline. Empirehouse collaborated closely with Ryan Companies from early planning through construction, providing design-assist services and innovative solutions to meet tight budget constraints and complex design challenges.

By prefabricating and pre-glazing the window wall system in-house, Empirehouse streamlined installation and tackled intricate slab edge conditions with precision. A standout feature is the 233-foot-long wind screen surrounding the rooftop pool deck, engineered with structural posts and heavy laminated glass for both safety and aesthetics. The project also included 228 custom terrace doors integrated into a 70,000+ SF window wall system, ensuring optimal air and water performance.

Scope:

• 70,715 SF custom window wall system with pre-glazed framing
• 228 fully integrated terrace doors with vacuum-sealed performance
• 233′ wind screen using heavy laminated glass + point-supported structural posts
• Just-in-time material delivery for efficient logistics
• LEED Silver Certified
• Awarded NAIOP MN Award of Excellence + Ryan Companies Subcontractor Safety Award

In 4-1/2 months, the Empirehouse glazing team completed the installation of 45,216 square feet of window wall and 3,662 square feet of terrace doors at the 17-story Portland Tower luxury condominium project in downtown Minneapolis, MN.

This downtown Minneapolis project was logistically challenged by its proximity to the new Viking Stadium in addition to the new Downtown East Commons Park, and other new commercial and apartment building work. All projects were under construction simultaneously with similar deadlines and within blocks of each other. Our glazing crew demonstrated tremendous teamwork by safely meeting aggressive schedules and site management challenges with no injuries.
