The study of coherent elastic neutrino nucleus scattering (CEνNS) offers the opportunity to explore fundamental neutrino properties and to search for physics beyond the Standard Model. The NUCLEUS experiment aims to precisely measure the CEνNS cross-section of reactor-antineutrinos produced by the Chooz nuclear power plant in France at low energies with gram-scale cryogenic detectors with ultra-low energy thresholds of O(10eV). The first science phase, NUCLEUS 10g, will deploy two detector modules, each containing nine cryogenic target detectors embedded in an inner veto. I will present the development of the first versions of the NUCLEUS 10g detector components as well as further strategies towards the full cryogenic detector, which will consist of the two detector modules, a LED calibration system and a cryogenic outer veto. The research was supported by the DFG through the Excellence Cluster ORIGINS and the SFB1258, and the ERC Starting Grant 2018 "NU-CLEUS".
