Empirehouse teamed with Greiner Construction and Architect Yellow Dog Studios as the Architectural Glass, Metal and Glazing Contractor for the Lindquist & Vennum law firm project.

Empirehouse’s glass and glazing scope of work on this renovation project included installing a three-floor floating spiral staircase with glass railings and a sliding glass wall system. This floating spiral staircase is part of an 81,000 square feet office renovation in the downtown Minneapolis IDS Center 19-21st floors. The staircase is a central focus connecting the three levels of this law firm and encourages an environment of interaction.

The completed floating spiral staircase with glass railings connects three floors of office space.

Retractable window wall

In addition to the floating spiral staircase with glass handrail, Empirehouse installed a retractable glass wall that vanishes into a channel within the wall when not in use.
