A cornerstone in the city’s efforts to revitalize the Burnside Bridgehead area, Slate rises on a previously vacant lot. Opened in Sept. 2016, the project spans 147,000 sq. ft. and offers 75 market-rate apartment units on the upper six floors; 35,000 sq. ft. of creative co-working office workspace on the second and fourth floors; and 7800 sq. ft. of retail space at street level.

Designed by Works Progress Architecture for co-developers Urban Development Partners and Beam Development, the property conveys a “push and pull” theme exemplifying the location’s vibrancy. The glass, metal and concrete façade consists of articulated, modulated, rectangular shapes, including some that are setback and some that project over the sidewalks below.

“It creates the illusion of a shifting stack,” describes Works Progress Architecture’s Ian Roll. “On the North and South sides, the curtainwall has a flat, clean, crisp look that transitions to a sculpted, figural texture on the East and West elevations. The curtainwall is crucial in registering the intentional lines and visual elements.”


The high energy-efficiency building features window, entrance and unitized curtainwall  systems by Wausau Window and Wall Systems. Roll notes that the firm worked closely with Wausau Window and Wall Systems from the project’s earliest stages.

Wausau Window and Wall Systems provided more than 40,000 sq. ft. of INvision 7250i-HRX SSG Series unitized curtainwall and 7250 Series SuperWall; 240 project-out awning 4250Z zero sightline windows; and 4250i-TD Series terrace doors and D5100 Series sliding patio doors.
