This renovation of a historic building opened in the Fall of 2008 in the area that he dubbed "NuLu" for the East Market District. It used to provide offices for sonaBLAST! Records, Holland Brown Books and The Group Entertainment. They then went on to landmark and develop almost a block of neighboring historic buildings. He is the author of two fund-raising art books for children, "Louisville Counts" and "L is for Louisville." Louisville Magazine named Gill its 2009 Person of the Year.
