Clair is surprised when Cliff shows her plans to add on a soundproof room to the house where she can escape the children. Cliff and Clair have co-signed a loan for Sondra and Elvin to get their first home. They sell their apartment, and are set to move, but then the couple that is selling the house that they want to buy files for divorce, complicating the sell, and in the process, leaving Sondra and Elvin homeless. They beg Cliff and Clair to let them and the twins stay in Martin and Denise's room while they are away in Japan, and when Cliff agrees, he forgets about the idea of adding on the room for Clair because he feels like he will never be able to escape the children. So instead of building the addition, they decide to build on an addition to the kitchen.
