Recently married Peruvian-born couple Alex and Pam Grahammer -- along with Alex's twin seven-year-old sons -- live in a quaint Washington, D.C., home. But their tiny kitchen is so crowded that the refrigerator and basement doors can't be accessed at the same time. Outside, their deck is unsafe for the twins, and mosquitoes from the neighboring park like to feast on the family. So Dean and Derek create an outdoor kitchen and dining area to help expand this home before the Grahammers start expanding their family. Plus, they'll finally get some relief from those pesky mosquitoes.
