I think it should be possible to build marble houses, With marble walls, not just a marble roof, and finally put a use to the marble pillars that currently are just placed to look like they are part of a structure and using marble pillars for support beams if you want an open wall similar to the Parthenon. The pillars would be a wall building function. Also pillars could be built like they are now and moved for those people wanting to make it look grand inside their house. Also an overhanging roof with pillars would look really cool. How nice would it be to build your houses like this or your temples, i'm not looking at the artwork, but how its built, the beautiful giant stone pillars holding the roof up above your head tons of stone high above your head. The pillars holding a roof, the thick stone roof, the pillars holding a roof, HOLDING A ROOF New Idea, you know how you have the arched walls on a wooden house as an option, how about arched walls with stone pillars, just to add on to this nice feauture
