I present results from the recently completed VIPERS redshift survey which has obtained spectra for ~100,000 galaxies at redshifts 0.5-1.2 over 24 square degrees. By combining VIPERS and SDSS datasets, we explore the relationships between star-formation history, stellar mass and galaxy structure and how these relationships have evolved from z~1 to the present day, focussing in particular on the high mass limit of the blue cloud, beyond which galaxies cannot continue growing through star formation. I show how this high-mass limit has evolved significantly over the last 8 billion years, retreating steadily to lower stellar masses towards the present day, but also depends strongly on galaxy size, revealing a fundamental link between galaxy structure and "mass quenching".
