At the beginning of the book you can see a table of contents. On the basis of this it becomes aware that the book deals with very different elements, such as chimneys or ceilings.
The book has its own setup. As you can see here, there is always a drawing on the right page and the left page is left empty. The book does not have a text. Every single illustration is drawn in a very realistic way. A scale is underneath the drawing to show the size of the represented element.
At the end of the book the general rule is broken. The drawing is represented on two single pages. It differentiates this passage from the rest of the book.
