Upcoming spectroscopic and photometric surveys such as the Euclid mission will measure the large scale structure (LSS) of our Universe to an unprecedented level. LSS data not only contains information about dark energy but allows us to constrain the sum of neutrino masses and primordial non-Gaussianity as well as to test gravity. I will present an overview of the observational effects of these extensions to the vanilla ΛCDM model on the LSS, discuss expected constraints and provide an outlook of potential theoretical and observational challenges.
