Diane and Anthony enjoy the good life in their large home, but with five kids even a big house can be bursting at the seams. With a family this size they need to use every inch and they have a dining room and living room that are sitting unused. Heather comes to the rescue with a plan that will move this family into the next decade… but this reality design series will see handy Diane and unhandy husband Anthony pushed way out of their comfort zones. Diane cannot envision her home without bright vivid colours and Anthony is craving soft neutrals. They also disagree about the use of space; Diane wants to get out the sledgehammer while Anthony takes a more cautious approach. Will Jon inspire as well as teach? Will Heather’s design choices leave this couple at odds?
