Construction has begun on 79 W. Monroe in Chicago, the city's first office-to-residential conversion under the 'LaSalle Street Reimagined' initiative. The historic 14-story Rector Building will be transformed into 117 residential units, including 41 affordable ones, with upscale amenities and a "Neoclassical Nautical" design blending beaux-arts architecture with maritime elements. Preservation efforts include restoring masonry and upgrading windows for energy efficiency.
