This book is full of layout tips. It's divided into 15 chapters, and showcases various home layouts. I actually used this book as a reference when building my own house. It's a book created by the architectural firm, Freedom Architects. If you purchase this item with other items, we will discount the total price by 50 yen. I'm decluttering due to a move.
