The second edition of this manual comes five years on the heels of its highly demanded predecessor. It attempts not only to update the information contained in the first edition but also to introduce the latest innovations in alternative residential construction. Some systems have adapted to keep up with an increasingly technologically-minded construction industry while others have failed to survive for a variety of reasons. Inclusion or exclusion in this report is by no means an endorsement or condemnation by the Shimberg Center for Affordable Housing and the University of Florida.
