"The Equation of Floor Plans: The Art of Assembling a Comfortable Home" Yutaka Iizuka Price: ¥1800 I used this book as a reference for new single-family homes and apartment renovations. It describes various ways of thinking about floor plans. I also sell other housing-related books, so please take a look. I purchased this book used, so there is some minor soiling. Please check the photos. #YutakaIizuka #Yutaka_Iizuka #book #CivilEngineering/Architecture"
