  We revisit supersymmetric solutions to five dimensional ungauged N=1
supergravity with dynamic hypermultiplets. In particular we focus on a
truncation to the axion-dilaton contained in the universal hypermultiplet. The
relevant solutions are fibrations over a four-dimensional Kahler base with a
holomorphic axion-dilaton. We focus on solutions with additional symmetries and
classify Killing vectors which preserve the additional structure imposed by
supersymmetry; in particular we extend the existing classification of solutions
with a space-like U(1) isometry to the case where the Killing vector is
rotational. We elaborate on general geometrical aspects which we illustrate in
some simple examples. We especially discuss solutions describing the
backreaction of M2-branes, which for example play a role in the black hole
deconstruction proposal for microstate geometries.
