A support is a buildable structure in Stranded Deep. A support, as the name suggests, helps to support the structural frame of one's shelter. Building a support requires the use of a single stick placed next to an existing foundation, as well as any type of Hammer to build and place it.

Once crafted, a support can be placed on any of the four corners of a foundation. At least two supports are required to be placed adjacent to each other being able to place either a Door or a wall in between them; four (one in each corner) are required to be able to place a roof on top of them.
