I am a last semester interior design student and just bought this book-I wish I had had it from the start! The book has nice sections on historical periods and furniture dimensions, residential, office, hospitality, retail, health care, banking and public restroom spaces, with lots and lots of plans, elevations and sections for each category. There is also a general reference section at the back of the book with lots of tables (space planning, wall covering or yardage amounts, as well as electrical and math tables). As well there is a nice colored section of wood and marble samples-a real time saver indeed!
