🏆Alteration: The largest project approved last week was a $50 million conversion at 19 South La Salle Street, where plans were greenlit for interior and exterior alterations to convert the existing 17-story office building into a mixed-use property. The landmark 132-year-old building was designed by William Le Baron Jenney, widely credited as the father of the skyscraper. The conversion project will feature ground-floor retail, a 32-room hotel across the second and third floors, and 175 residential units spanning the fourth through 16th floors, along with a partial 16th-floor rooftop deck. Envoi Partners is the owner, and the architect is James Plunkard.
