Ladder

A Ladder is a building in Survival 303.

Overview
A Ladder is a building that can be climbed up. It is made at a stone workshop using small tree stumps, and has the sole purpose of being a modular, climbable structure. Owing to the large number of wooden parts, it can be a pain to fireproof. Most players just place down three small tree stumps instead because they're higher.

Interestingly, both the simple tower and the shelf can also be climbed like the ladder. Since the shelf is made of planks, it's arguably cheaper for players with access to large trees and a lumbermill.
