Prefab Shelf

Shelf is a decorative building made from flat-packed pieces that can be assembled in various ways. It is one of the more flexible-looking furniture pieces in Oxygen Not Included, intended to fit into a colony’s interior without drawing attention to the fact that it was built from a simple prefabricated kit.

Its main distinction is appearance: the shelf can be arranged in different ways, and the result is described as looking surprisingly nice. Because the available source material does not provide construction data, storage behavior, or mechanical effects, the shelf should be treated here as a visual furnishing item rather than a utility building.
