The title (architecture moderne) implies, that the book examines the modern architecture of this time. The second part of the title specifies the goal of this book: the art of building well. It also clearly empathizes who this book is for: for all kinds of people (pour toutes sortes de personnes).
The book is divided in six books:
- The estimate of costs
- The measurements of the buildings
- Uses and customs
There is a much more detailed index which is mainly structured in articles and distributions. The articles have themes like counter walls and windows in different situations. Some articles are formulated in a question (Fenêtres en mur particulier & comment?). All the articles in the index are on a very specific theme, situation or problem.
Especially the second part, which is more than half of the book, consists only of illustrations. There are many ground views and sheer plans. All of them are very detailed. In the version which is part of the ETH rara archive there are also drawings of tools you need for constructions (for example cranes). In the ground views all the rooms are named so one can clearly identify their function.
The book is rather big and most likely to be used in the planning stage. It probably served as a reference book. You can get inspirations for your draft and find ideas on how to build the desired building.
