Andrew and Mandy want to expand their tiny, outdated house by building a stairway to access their unfinished attic. Ultimately, they plan to convert the upstairs into a new master suite. While Andrew has no doubt that he and Mandy will make a great team, Andy's disorganization and lack of skill push Mandy into major meltdown mode.

Darren and Ellen love everything about their house. Only problem is, it's way too small for their family. So they've decided to add a 500 square foot addition to the back of their home. Ellen and Darren have successfully tackled DIY projects in the past, but quiet is not in their vocabulary - neither is understated, calm, objective or patient. So this massive undertaking could get interesting.
