When Sam the library mouse and his friend Sarah wake to find the library being packed up to prepare for a major renovation, they realize they won’t have a home during the construction. So off they go in search of a new place to live. Sam knows research is key, so he finds books about architectural styles to get ideas for building a temporary home from objects found around the library. They build and live in a variety of houses: a castle, an igloo, a yurt, a modern house, and even a geodesic dome. But none feels like home to Sam. Finally, though, the renovation of the library is complete, and they can move back to their true home, the library!

The book includes photos of the real house styles discussed in the text and a relevant glossary of architectural terms.
