A dinosaur has come back to life in the red-hot Arts District.  Five years ago, the AMP Lofts endeavored to create 182 condo units with ground floor retail near the intersection of Santa Fe Avenue and 7th Street.  Like many real estate developments that emerged during the Great Recession, the Koning Eizenberg designed project sat dormant while awaiting sunnier economic conditions.  Rainy skies may gloom above Los Angeles today, but it looks like the numbers finally pan out for the long awaited residential development.  A partnership lead by Bolour Associates purchased the property over the summer, and today they submitted revised plans for a mixed-use development to the city.  The as of yet unnamed project at 695 Santa Fe Avenue would consist of 240 live work units above 20,000 square feet of commercial space.  Replacing KEA as design architect is the Arts District based Shimoda Design Group, whose previous work includes Hollywood's proposed Ametron Tower.  Preliminary renderings show a six-story structure centered around an elevated 25,000 square foot central park.  At ground level, a commercial courtyard would provide up to 15,000 square feet of retail space and 10,000 square feet of outdoor seating.  Residential amenities include an outdoor pool, "world class gym," and a sauna.  The unexpected revival of the former AMP Lofts project caps what has been an eventful year for Downtown's easternmost neighborhood. The Arts District got plenty of mixed-use action, a trendy grocery store, and more media attention than it knew what to do with during 2013.  Here's hoping that 2014 is even better.
