Systems and methods for modular housing and modular housing units are provided. A modular housing system for defining a structure having an adjustable living space, includes: a first housing module for human habitation, the first housing module having at least a section of a side absent; a second housing module for human habitation, the second housing module having at least a section of a side absent; an intermodule connector for connecting the first housing module to the second housing module when the first and second housing modules are positioned such that their respective absent sections are adjacent, thereby defining a continuous space; wherein the adjustable living space of the structure can be adjusted in a plurality of stages, the stages comprising: a first stage wherein the first housing module defines the adjustable living space of the structure; a second stage wherein the first housing module and the second housing module define the adjustable living space of the structure, the first and second housing modules connected via the intermodule connector; and a third stage wherein the first housing module defines the adjustable living space of the structure, the second housing module having been disconnected from the first housing module and removed so that the size of the adjustable living space of the structure is decreased relative to the second stage.
