  We show that the general method of Lie algebra expansions can be applied to
re-construct several algebras and related actions for non-relativistic gravity
that have occurred in the recent literature. We explain the method and
illustrate its applications by giving several explicit examples. The method can
be generalized to include the construction of actions for ultra-relativistic
gravity, i.e. Carroll gravity, and non-relativistic supergravity as well.
