Keep this mansion's existing size, complete interior, room layout, floors, stairs, ceilings, and furniture. Restyle the exterior into a dark medieval manor: - dark oak / spruce timber walls - polished blackstone and deepslate exterior stone - dark deepslate roof - warmer brown facade - larger windows - detailed front entrance - multiple dark gables - flower boxes and greenery Add a glass greenhouse attached to the left side. IMPORTANT: Preserve the complete furnished interior. Do not hollow out the mansion. Do not increase the overall house size. Do not replace the interior with empty space. Use only my selected block palette.
