We present the results of short baseline interferometry observations at submillimetre wavelengths, using a two-element interferometer comprising the JCMT and CSO, of circumstellar discs around young YSOs. We model data for the Class 0 protostar IRAS03282 and the Class I protostar L1709B with discs and compare them with previously published results. We find evidence for the ratio of the disc mass to envelope mass to increase as the objects evolve.
