The first move-ins aren’t expected at the Art’s District’s One Santa Fe complex until Fall 2014, but construction crews are now busy attaching alabaster hued cladding on the $160 million project’s eastern facade.  The quarter-mile long structure will feature 438 apartments, 80,000 square feet of ground floor retail, and perhaps a direct link to a future Arts District extension of Metro’s Red and Purple Lines.  While the residential population of the Arts District is not yet large enough to sustain a heavy rail station, a couple of nearby projects currently in the works will help change that.  Two blocks south on 3rd street, a 320-unit development from Lowe Enterprises is under construction on the site of the former Mega Toys warehouse.  Legendary Development also has plans for a seven-building, 472-unit development on the vacant lot that sits adjacent to SCI-Arc.
