The Lombucket Industries Tree House is an area that acts as Hannah's home on Owl Island. It is a large area on top of the trees on Owl Island, consisting of: a storage area, farm areas, and a small housing area.
The Lombucket Industries Tree House first appeared in Hannah Plays! - Tekkit - 1. Owl Island Warehouse. In this episode, Hannah shows what she has accomplished so far and what some of her future plans were. The treehouse is not used in more recent Tekkit episodes due to the far more useful storehouse on the island.
