Large volume models are a method of moduli stabilisation in string theory that breaks supersymmetry at a hierarchically small scale. I give an overview of this class of models and their phenomenological properties. I describe how the models relate the weak, axionic and neutrino mass scales in a phenomenologically successful way. I review the computation and structure of the soft terms and the susy particle spectrum. I finally describe how the models predict a new physical scale at ~1 MeV.
