There's another ancient building technique that doesn't get considered in the modern era: cutting and moving gigantic 10-ton blocks of stone. Sure, it's expensive to cut and move, but a bunch of dudes with rickety boats did it across huge expanses of land and water, and their structures also still stand today. If the carbon footprint is a concern, it might be a perfect opportunity to propose alternatives to the carbon-intense techniques we've adopted. For example, William Fairbairn invented a hand-powered crane, whose 642-to-1 ratio meant two men turning cranks could lift 60 tons. Our land and water-born vessels could also probably be innovated on with similar efficiency, if it wasn't so damn easy to burn ancient vegetation.
