A modern addition to a vintage Chicago greystone at 3731 North Sheffield Avenue is rounding into form in the Wrigleyville neighborhood. The new four-story portion, permitted in August of last year at a reported cost of $2.5 million, has completed exterior masonry work and installed its windows. Work remains to be done to terraces on all four levels.

As for the original building, a single-level addition atop the third floor is ongoing, while bay windows facing west onto Sheffield Avenue have been removed to create outdoor space for all three levels.

City Council approved the project in spring 2023. A permit was then issued in October 2023 to begin selective demolition of the interior and the enclosed rear stairway. Designed by Jonathan Splitt Architects, the expansion converts the original six-unit residence into a combined eight dwelling units. Off the rear alley will be access to a two-car garage on the ground floor of the addition, as well as four surface parking spaces. A basement is included with the new building, according to the August 2024 permit/ Check out Chicago Yimby for full article!
