Mr. Thatcher has been working to build the perfect house. And working. And working... and so, quite by accident, the house grows and grows in size. But it never seems quite like home. When a crowd of characters from his storybook neighborhood show up looking for a place to stay, Mr. Thatcher cries It's not perfect yet! You don't want to stay here! But soon he finds that what makes a house a perfect home has nothing to do with the craftsmanship and everything to do with the friends and family inside it.
