Ideal Body Shop, which has operated in a brick building on South Park Street since 1924, could be replaced by a five-story apartment building with commercial space on the ground floor. A meeting of the Greenbush Neighborhood Association at 6 p.m. Monday at the Neighborhood House, 29 S. Mills St., will hear plans to raze the iconic garage and replace it with roughly 75 apartment units. Three adjacent rental houses on Drake Street would also come down.
