Tree House Trouble

After looking at dozens of properties, Ken and Mark settled on a cabin-inspired home in the woods that was a foreclosure and needed a lot of work. The couple had dabbled in DIY renos in the past and thought they could tackle the project themselves, but little has been done in five years. Ken has had enough and is ready to abandon this house that no longer functions for them, but Mark still believes the home has potential and is desperate to make it work. Will designer Hilary complete their long to-do list, or will real estate agent David find them a new space that the couple can enjoy together?
