Build a cohesive, vibrant Minecraft...

Build a cohesive, vibrant Minecraft city layout featuring exactly 12 unique houses and 1 central castle, following these strict parameters: 12 Residential Houses: Each house must have a fully detailed, custom interior (furniture, lighting, flooring, and functional spaces like kitchens and bedrooms). Every house must feature a distinct roof color made using a different type of Concrete block (12 unique colors across the 12 houses). Architecture should feature a modern or suburban aesthetic that pairs well with smooth concrete roofs. 1 Central Castle: Must feature a impressive exterior with classic medieval/fantasy elements (towers, ramparts, stone brick textures). Layout includes exactly 3 medium-sized rooms. No interior inside the castle (empty floor plans ready for future builds).
