  Dimensional deconstruction (DD) abstracts from higher dimensional models
features of related 4--dimensional ones. DD was proposed in Refs.[1,2,3] as a
scheme for constructing models of {\it naturally} light composite Higgs boson.
These are models in which--{\it without fine--tuning of parameters}--the
composite Higgs's mass M and vacuum expectation value v are much lighter than
its binding energy scale \Lambda. We review the basic idea of DD. It is easy to
arrange M << \Lambda. We show, however, that DD fails to give v << \Lambda in a
model that is supposed to contain a naturally light composite Higgs [4].
