Nack Development’s May purchase of Innovative Images on Main Street will become a restaurant with a rooftop terrace, Nack Development President and owner Donny Churchman said.  While the upcoming restaurant still cannot be announced, Churchman said the rooftop terrace will overlook the future 4th Street Plaza. The restaurant is aiming for a 2020 opening, he said. “It depends on the approval process,” Churchman said.  The restaurant will replace Innovative Images on Main Street.[/caption] Current project updates Churchman and Nack Development have four ongoing projects in the Rail District to revitalize Frisco’s downtown. He said The Patios at The Rail, a three-story building with restaurants and rooftop patios, is on track to finish by end of 2019. “We’re almost 100% leased out,” Churchman said. The luxury townhome project, The Tower at The Rail, is on track to be completed at the end of 2019 as well, he said. The Nack Development started groundwork for the future home of the North Texas Performing Arts’ Frisco Youth Theatre, or the Nack Theater. “The first performance will be in March of next year,” Churchman said.  Lastly, Churchman said The Calaboose at The Rail project, which will have residential Brownstone homes and office space, currently has no construction timeline.   What's coming Churchman has more on the horizon for Frisco. Nack Development is currently working on a project of acquisitions involving the arts.  “I’ll be working with [Tammy Meinershagen] with Frisco Arts and collaborating with them on that,” Churchman said.  Even further down the line, Churchman said he is working with the city to plan for Frisco’s downtown once the population gets to 300,000. “We want to be known as the best downtown in the country for that size,” Churchman said.
