Construct the main structural frame using high-strength white oak beams anchored with specialized tree-friendly bolts. This ensures the floor can support the weight of the optics system without damaging the tree's vascular system.

Install the central hollow-core mast containing the secondary mirror assembly. This vertical conduit is vibration-dampened to prevent image distortion from swaying branches during light breezes.

Mount the weatherproof, high-precision periscope lens at the highest point of the canopy to capture a 360-degree field of view. The assembly is shielded by a glass dome that resists debris accumulation and UV radiation.

Finish the interior with a concave mahogany ceiling panels that serve as the projection surface. A manual gear system allows guests to rotate the internal prism to adjust their focus from the forest floor to the distant horizon.
