These photos do not show actual staircases or custom tree house exteriors. In your ReTreet, you will have two staircase options: Standard Staircase A metal 60 degree ladder/stair is attached to the tree trunk at the top and rests on piers at the bottom. The ladder allows easy access through the tree house trap door. This staircase style enhances the natural silhouette of the tree. Custom Staircase For an additional charge, a fixed, integral metal staircase with intermediate deck will replace the standard staircase. It will lead to a suspended landing that may be used as a small deck. On the landing, you will turn 90 degrees to ascend a sloped ladder through the trap door in the floor of the tree house. Strategically placed tree branches help provide safety railings for the stair and deck structure.
