9. Birch Lighthouse on the Coast

If your world has a coastal area, building a birch lighthouse can combine beauty and functionality. Construct the tower with birch logs and planks, and make the top glow with lanterns or sea lanterns. A spiral staircase inside leads to the viewing deck. This design not only looks amazing but also serves as a navigational aid for exploring the ocean.

Tips: Surround the lighthouse with sand, shells, and beach decor for realism.
