MINNEAPOLIS — RJM Construction, a Minneapolis-based general contractor, will oversee construction of Legacy Lofts, a condominium project in downtown Minneapolis’ mill district. Led by Jim Stanton, the 1 million-square-foot project will include a 14-story and an 18-story tower with underground and aboveground parking along with 374 individually owned units. Plans call for a playground, pet exercise area, fitness room, pool and spa, bike racks, community room, game room and a green roof with lawn bowling. RJM Construction will manage the core and shell construction. Riverdale Ventures LLC, which Stanton owns, will complete the units. Site preparations are underway, with the building scheduled for completion in summer 2018. In addition to RJM, project partners include Oertel Architects and BKBM Engineers.
