The best new building won't be there much longer. It will be taken down not because it is an historic landmark no one cared about but because it wasn't meant to last. But while it stands, it's incredible to behold. Artist George Sanchez decided to create a model of the famous 1929 Le Corbusier house in France, an exquisite example of modernist architecture, and put it up underneath the I-395 underpass off NW Thirteenth Street. That's right -- Overtown at its most blighted decrepitude. It sits clean and sleek -- at night it glows -- amid the concrete and filth of Miami's neglected urban core. Sanchez called it "The Blessing." Maybe that's what the city will need to follow the artist's path and create permanent beauty and hope in an area too long without it.
