270 Michigan is a recently renovated six-story building sitting on the west side of Michigan Avenue just south of Seneca Street. The renovation of this property was completed in December 2021. Previously home to the Buffalo Envelope Company, the building has been converted into a mix of uses including commercial office space on floors 1 – 3 and market-rate apartments on floors 4 – 6. We worked in consultation with the NYS Historic Preservation Office and National Park Service to restore the building for designation on the National Register of Historic Places. Exterior work included replacing the existing windows with new windows that matched the historic windows removed by a previous owner. Interior work includes the preservation of an historic staircase and elevator, restoration of original hardwood flooring and wood ceilings. Ample on-site parking is available on site.
