Two newlyweds, Tomiko and Naosuke, decide to build their dream home, and hire an old friend named Yanagisawa to design it. Unfortunately, Yanagisawa isn’t licensed to build homes, so they call in the wife’s father, Chouichirou Iwata, a retired carpenter, to help out. When Yanagisawa’s contemporary ideas clash with the old carpenter’s traditional Japanese methods, the project becomes a huge mess.
