From Halopedia, the Halo wiki
The tree house was a platform a 100 meters off the jungle floor on the planet Onyx, in the titan arms of a banyan tree. The only electronics it had were a radio, an automatic gun turret, and an AI projection unit; everything else was low-tech: optic binoculars and telescopes, parabolic sounds collection dishes, and "good old-fashioned" signal flags. This was used by Kurt-051 for observation.
It was destroyed during the events of the Onyx Conflict.
