Ranking the points of Vitruvian Triad from most to least important I would put firmitatis as most important. Firmitatis means stability and a buildings stability is the most important trait in my opinion because it could be a beautiful building but if its unstable and falls apart its beauty is good for nothing. Second, I would rank utilitatis which means utility, a building needs to have a useful purpose or else there would be no point in building it. Lastly I would rank venustatis which is beauty. I rank this last because beauty is in the eye of the beholder.
