Goal: Build a large, highly detailed Gothic medieval castle inspired by cathedral-like high Gothic architecture mixed with fortress elements (Gothic + military).

Keep the main axis mostly symmetrical, but add tasteful asymmetry for realism (towers of different heights, side wings, balconies, buttresses).
