watchtower, lookout, high building
楼 centers on a tall, multi-story structure used for observation: a watchtower, lookout, or any high building.
楼 combines 木 (wood) with 娄, which likely contributes the sound and the idea of a tall structure. The character originally referred to a wooden watchtower or multi-story building.
The left side is wood 木, and the right side 娄 looks like a tall framework with a roof. Picture a wooden tower rising high above the trees for a lookout.
For ロウ, imagine a low wooden tower that is actually a watchtower: low -> ロウ, and the tower stands tall despite its name.
