It is well known that Hopf-fibre T-duality and uplift takes the D1-D5 nearhorizon into a class of AdS(3) x S-2 geometries in 11D where the internal space is a CalabiYau three-fold. Moreover, supersymmetry dictates that Calabi-Yau is the only permissible SU(3)-structure manifold. Generalising this duality chain to non-Abelian isometries, a strong parallel exists, resulting in the first explicit example of a class of AdS(3) x S-2 geometries with SU(2)-structure. Furthermore, the non-Abelian T-dual of AdS(3) x S-3 x S-3 x S-1 results in a new supersymmetric AdS(3) x S-2 geometry, which falls outside of all known classifications. We explore the basic properties of the holographic duals associated to the new backgrounds. We compute the central charges and show that they are compatible with a large N = 4 superconformal algebra in the infra-red.
