This book contains hundreds of professional plans that form a portfolio of ideas and easy-to-follow prototypes for the homeowner in search of more space. Over 275 plans can be used for adding on to, renovating or completely remodeling existing homes. These plans can be modified or used as they are to enhance a wide range of house styles, from A-frame to colonial. They are accompanied by a discussion of architectural design guidelines and how to apply them, how to identify space and layout needs and how to evaluate cost trade-offs and establish priorities.
