Why Platform Height Matters
Building a treehouse isn’t just about aesthetics—it’s about safety, usability, and long-term enjoyment. The platform height directly influences:

Safety – Higher platforms can increase the risk of falls, especially for younger children.
-
Access – Stairs, ladders, or suspension bridges affect the comfort and safety of entry and exit.
