can you build a medium-sized solo hardcore base, 30×30 blocks, 2–3 stories tall. Ground floor (main hub): Central room or lobby (~10×10) with a door, bed, and chest storage Enchanting room with no table (9×9 minimum, with 15 bookshelves around a 5×5 area) Brewing/potion room (smaller, ~6×6) Second floor or adjacent: Farm area (a 9×9 crop plot is standard, plus maybe a small animal pen ~10×10) Extra storage / crafting area additions: Nether portal room with no obsiadian (small, ~5×5) A walled perimeter the whole thing for creeper/enderman protection
