The first trailer for the show, set in Nashville, debuted on Monday. And it looks like there's a some good family fun — and competition — in store for viewers. In the show, 29-year-old actress-singer Brandi and her mom Tish, 49, square off against each other by each trying to sell their vision for a design revamp to the same client. Whichever direction the client chooses, Brandi and Tish implement — with the architect of the winning design plan in charge and the other acting as her assistant.
