A vintage Chicago greystone building at 3731 North Sheffield Avenue is nearing completion of its extensive modern expansion in the heart of Wrigleyville. The ambitious renovation project features a new four-story addition that has recently finished its exterior masonry work and window installation, bringing the property closer to its final transformation.
The substantial addition, which received permits in August of last year with a reported construction cost of $2.5 million, represents a significant investment in the neighborhood's housing stock. While the brick-clad exterior appears nearly complete, construction crews are still working on terrace installations across all four levels of the new structure. The addition seamlessly blends contemporary design elements with the historic character of the original building.
The original greystone is also undergoing major modifications as part of the comprehensive renovation. A single-level addition is currently being constructed atop the existing third floor, expanding the building's footprint vertically. In a notable architectural change, the building's distinctive bay windows facing west onto Sheffield Avenue have been removed to create new outdoor living spaces for residents on all three levels of the original structure.
City Council approval for the ambitious project came in spring 2023, setting the stage for the complex renovation work. By October 2023, permits were issued to begin selective interior demolition and the removal of the enclosed rear stairway. The architectural design, created by Jonathan Splitt Architects, transforms the original six-unit residence into an expanded eight-unit residential building, increasing housing density while maintaining the neighborhood's historic character.
The project includes significant improvements to parking and accessibility. A new two-car garage will be located on the ground floor of the rear addition, accessible from the back alley. Additionally, four surface parking spaces will be available behind the building, providing residents with convenient vehicle storage in the densely populated neighborhood. According to the August 2024 permit documentation, the addition also includes a full basement level.
Property records reveal that the historic greystone was originally constructed in the late 1890s, making it well over a century old. The building was purchased in May 2021 for $1.645 million by Mangan Builders, operating under the business entity Wrigley Flats LLC. Mangan Builders is serving as both the developer and general contractor for the renovation project, maintaining direct control over the construction process.
The property enjoys an exceptionally desirable location in one of Chicago's most vibrant neighborhoods. Situated just one block north of Wrigley Field's centerfield bleachers, residents will have easy access to Cubs games and the bustling entertainment district. The Addison Red Line elevated train platform provides convenient public transportation access less than two blocks south on Addison Street. Multiple bus routes, including Routes 8, 22, 80, and 152, serve the area within a three-block radius, ensuring excellent connectivity throughout the city.
