After nearly two years of mystery, MetLife and JLL have begun to reveal their vision for the reinvention of a primely situated Midtown block now dominated by surface parking.

According to multiple sources, the development duo have announced plans for an office tower at 1295 Spring Street, between 16th and 17th streets, near Arts Center MARTA station.

The initial tower, which would bring more than 500,000 square feet of office space and nearly 100,000 square feet of street-front retail, would rise on the site of the eight-story Arthritis Foundation building.

A pedestrian promenade would run through the site, stretching from Spring to West Peachtree street.

The assembled site includes parking lots along Spring Street, behind the Artmore Hotel, the six-decade-old Arthritis Foundation building (which was once proposed to be transformed into apartments), and a small office building.

Bisnow reports the 25-story office project is anticipated as merely the first phase of a much larger intervention on the 8.5-acre site. Eventually, the project would include a hotel and a 350-unit apartment building.

Miami-based architecture firm Arquitectonica created the master plan for the project, according to the Atlanta Business Chronicle, while Atlanta-based Cooper Carry is designing the buildings.

More details about the proposal will be revealed at this month’s Development Review Committee Meeting.
