Icon Mechanical’s rapid growth led to the need for a 41,000 square foot expansion of their current headquarters in Granite City, Illinois. The new two-story office building is directly adjacent to their former office and shop facilities. The tilt-up concrete exterior includes a subtle blend of neutral colors with Icon’s red branding accents in corrugated metal fabricated on site. Daylighting was a driving factor in the design, with three large skylights running along the center of the building, allowing natural light down through two atriums and into the first level. The new space is highly collaborative with several work cafés, an open lobby and lounge with a monumental stair and a hospitality conference space.
