We present the evolution of the size-mass relation since $z=1$ in the COSMOS region of the Deep Extragalactic VIsible Legacy Survey (DEVILS). We combine structural decomposition measurements with stellar mass estimates from fitting spectral energy distributions to multiwavelength photometry. We implement a novel technique to fit 2D light profiles to repeated observations, removing the requirement to co-add images, which maximises the effective signal-to-noise ratio and avoids issues arising when averaging point spread functions. The sample is then separated into distinct morphological classifications, which reveals that the size-mass relation of disc-dominated galaxies shows an overall flattened slope with very little redshift evolution over $0.3 < z < 1.0$. In contrast, spheroid-dominated morphologies show a much steeper relation and are generally more compact at a given stellar mass. The size-mass relations of bulge and disc components are also examined revealing that diffuse bulges occupy a similar region to disc structures, in stark contrast to the size-mass relation of compact bulges. Furthermore, the size-mass relation of discs becomes steeper in the presence of a compact bulge, whereas the relation for discs hosting a diffuse bulge is identical to that of pure-discs. The lack of evolution in disc-dominated galaxies (i.e. $R_\mathrm{eff} \propto (1+z)^{-0.13\pm 0.02}$) is inherent to their self-similar assembly. In contrast, the size-mass relation of spheroid-dominated morphologies is rapidly evolving despite minimal growth in the individual compact bulge components, with average sizes increasing at a pace of $R_\mathrm{eff} \propto (1 + z)^{-3.0\pm 0.2}$ and a slope that flattens with time as $\mathrm{ d}\log _{10}(R_\mathrm{eff})/\mathrm{ d}\log _{10}(M_{\star }) \propto (1 + z)^{2.8\pm 0.2}$.
