# 1000M

1000M is an apartment complex in the Historic Michigan Boulevard District portion of Michigan Avenue in the Chicago Loop. Designed by Helmut Jahn and Kara Mann, the building is a 73-story, 832-foot (253.6 m) tall tower located at 1000 South Michigan Avenue.
Construction on 1000M began in December of 2019 but was halted for a time due to the COVID-19 pandemic. It ultimately opened in June 2024. The building was the final project designed by Jahn.

## History

Construction was temporarily halted due to the COVID-19 pandemic. It began again in late 2021/early 2022. The building officially opened in June 2024.
A showroom for the building opened in 2017, with a scale model of the tower and four model units. The showroom also contained a video wall that displayed the view as would be seen from whatever unit a potential buyer is considering, thanks to footage recorded using helicopters and drones.

## Location

The building is located in what was previously a vacant lot at 1000 South Michigan in the Historic Michigan Boulevard District in downtown Chicago, Illinois. The site borders the 100-foot (30.5 m) Lightner Building at 1006 South Michigan and the 272-foot (82.9 m) Karpen-Standard Oil Building at 910 South Michigan. Located on the edge of Grant Park, the building will have views of the park and Lake Michigan.

## Ownership

The building is a joint venture between New York-based firms JK Equities and Time Equities, and Oak Capital.

## Architecture

The building was designed by architect Helmut Jahn. The tower is largely composed of glass with aluminum horizontal spandrels flanking each floor. The tower is capped with a 2 story east facing amenity space including an protected terrace with views toward Lake Michigan. Natural-finished aluminum spandrels, or bands between floors of the building, will create the image of a lightweight building.
Ethan Coleman, the development manager for Time Equities, and Jordan Karlik, a founder of JK Equities, talked to Crain’s Chicago Business about the design in March 2017. Coleman said the design of the tower "is something that really maximizes the light and views that residents will have." Karlik added of the architect, "Helmut was very passionate" about the exterior design of 1000 South Michigan Avenue.

### Interior design

Kara Mann, of Kara Mann Design, designed the interiors of the building, including the outdoor and amenity spaces. Mann said she wanted the interiors to have "a purity and lightness."

### Previous building designs

Plans for the building were released in August 2015. Although the historic district zoning has height restrictions of 425 feet (129.5m), on September 23, 2015 the City Clerk of Chicago's website posted that the building was planned to have a rooftop terrace reaching 1,030 feet (313.9 m). Blair Kamin of the Chicago Tribune later wrote that plans called for a 1,001-foot (305.1 m) tower. Eventually, the building was redesigned to stand 832 feet (253.6 m). The plan was approved on April 22, 2016. Instead of the more common setback architectural design, the original building would have had overhangs on its south face with successively larger rising cubes that Blair Kamin referred to as presenting a "striking, if somewhat precarious, effect".
Based on an October 29, 2015 presentation, the planned 506-unit building was to include 358 condominiums and 148 rental apartments between the 100-foot (30.5 m) Lightner Building at 1006 South Michigan and the 272-foot (82.9 m) Karpen-Standard Oil Building at 910 South Michigan on what has been a vacant lot. The early designs for the building included an 85th-floor roof deck for condo residents. The property, which overlooks Grant Park, had been owned by Warren Barr who had plans for a 40-story condominium tower until he lost ownership through foreclosure to First American Bank in a July 2010 proceeding that saw the property sell for $11.3 million. If completed, the building will surpass the 430-foot (131.1 m) Metropolitan Tower at 310 South Michigan as the Historic Michigan Boulevard District's tallest structure. Even after redesigns reducing the building's height, it remained the tallest building along Michigan Avenue in the Historic Michigan Boulevard District across from Grant Park.

### Height

The Commission on Chicago Landmarks has jurisdiction over the proposal due to its placement in the Historic District. In February 2016, The Landmark Commission considered formalizing a 900-foot (274.3 m) height restriction in the region of the historic district between 8th and 11th streets. Subsequently, the tower's height was scaled-back to 832 feet (253.6 m) and the building was redesigned to employ the current curving silhouette.
When completed, the building will surpassed the 430 feet (131.1 m) Metropolitan Tower at 310 South Michigan as the Historic Michigan Boulevard District's tallest structure. It will also become the tallest building in the city south of the Willis Tower. Even after the shorter redesign, the building retained the claim as the tallest building along Michigan Avenue in the Historic Michigan Boulevard District across from Grant Park and the 13th tallest building in the City of Chicago.

## Usage

Residences include studios and penthouses. The building also contains 80,000 square feet of amenities, including a rooftop observation deck, a fitness center, and pools.
