Every day, millions of North Americans work, shop, dine, study and play in the more than 300 public and commercial structures and 5,000 private homes nestled in the earth. Underground buildings are safe, attractive, useful and comfortable places to frequent and live. More than 100 underground buildings are included in this fascinating subterranean tour.

Hall has written four books and hundreds of magazine articles and reference book chapters. Six of these reference books won a total of 13 awards. Hall now concentrates on the areas of architecture, engineering and construction. She is certified as a Green Building Technical Professional.
