Four Walls is a book that was created to help raise awareness of the issues within public housing in the US. This book focuses on the Queensbridge Houses in New York City, which is the largest public housing development in the US.
The pattern included on the left page is a traced from a satellite image of the projects. This graphic element is used throughout the book to help tie it to the site.
The book is broken down into three sections; location, design, and people. Each of these portions aims to describe the Queensbridge houses from a different perspective.
By isolating different systems of structures to a satellite image, the housing projects begin to look similar to certain prison designs. This helps us further understand how public housing is viewed today. 
By relegating lower income communities to poor living conditions, it further enforces a divide in our population. Chronic underfunding of public housing systems is a widespread issue that must be addressed.
