  We unify k-Poincare algebra and k-Minkowski spacetime by embeding them into
quantum phase space. The quantum phase space has Hopf algebroid structure to
which we apply the twist in order to get k- deformed Hopf algebroid structure
and k-deformed phase space. We explicitly construct k-Poincare-Hopf algebra and
k-Minkowski spacetime from twist. It is outlined how this construction can be
extended to k-deformed super algebra including exterior derivative and forms.
Our results are relevant for constructing physical theories on noncommutative
spacetime by twisting Hopf algebroid phase space structure.
