Flavor deconstruction refers to ultraviolet completions of the Standard Model
where the gauge group is split into multiple factors under which fermions transform nonuniversally.
We propose a mechanism for charging same-family fermions into different factors
of a deconstructed gauge theory in a way that gauge anomalies are avoided. The mechanism
relies in the inclusion of a strongly-coupled sector, responsible of both anomaly cancellation
and the breaking of the non-universal gauge symmetry. As an application, we propose
different flavor deconstructions of the Standard Model that, instead of complete families,
uniquely identify specific third-family fermions. All these deconstructions allow for a new
physics scale that can be as low as few TeV and provide an excellent starting point for the
explanation of the Standard Model flavor hierarchies.
