#1 Amazon Architecture Bestseller for 20 consecutive weeks since publication!!
A key historical and guidebook on architectural cross-sections.

And the first comprehensive analysis of what a cross-section is and what it does.

What are the different types of cross-sections, and how do they influence form, space, materials, and program? What types of cross-sections do architects combine to achieve the desired effect in their buildings? How do cross-sections function as tools to demonstrate and create spatial relationships?
This book, The Essentials of Sections, explores these questions and more, providing a conceptual and practical framework for understanding the section as a crucial technique in architectural presentation and design.
Paul Lewis, Mark Churumaki and David J.
Lewis (Partner at LTL Architects) defines a new typology of cross-sections, illustrating them with detailed and detailed cross-sections of 63 historically significant buildings.
Each drawing is completed through extensive research and study and is presented with an analysis of the important role cross-sections play in architectural design.


This book proposes a way to understand the complex and important role that sections play in architectural planning and practice.
Discussions and debates about a particular building section are common in architectural research and practice.
However, there is no shared framework for evaluating or determining cross-sections.
What types of cross-sections are there, and what functions do they serve? How can these cross-sections be created? Why is one cross-section chosen over another? This book explores these questions and provides a conceptual framework, resource, and tool for understanding cross-sections as a means of creating architecture.
