My personal "founder fantasy" (not a founder type at all) for the last ten years or so has been a renderer/plugin for architecture visualisation that simulates weathering. For exactly the reasons you state. If you want a building to still look good after the honeymoon phase is over, you have to consider how it will look after a few years of realistic maintenance. If an architect talks about sustainability (and they all seem to do, these days), unless they can show evidence of having considered aesthetics after two decades of minimum maintenance it's all just babble.
