What makes a house a home? It goes way beyond merely having a roof over our heads. Here are twenty houses that explore that question, defining the idea of home with an entry hall filled with light and color…a stunning landscape through every window…a handsome fireplace lending warmth and joy…and so many more special, meaningful touches that say “Welcome home.” These welcoming homes are from Tarme, the Mexican design workshop, and Casas20Houses is the latest in the series of books about its projects.
