A pair of Columbus developers is proposing a 15-story tower on West Broad Street in Franklinton, continuing the transformation of the neighborhood. The $50 million tower, on the southwest corner of West Broad and South Gift streets, would include 206 apartments in the top 11 stories, above parking, commercial and retail levels. A rooftop lounge with a view of Downtown would sit on top of the T-shaped building. About 75% of the apartments would be priced to be affordable for families making 80% to 100% of the area median income, which in Franklin County is $58,700 for a one-person household and $83,800 for a family of four. The plan expands and modifies a November proposal for the site, which called for 80 apartments in a 13-story tower.
