Modular structures and rotatable hinges included in same

A rotatable hinge used within a modular structure, the rotatable hinge comprising:

• a base plate including a first surface and a second surface positioned opposite the first surface;
• a plurality of hinge knuckles integrally formed on the first surface of the base plate, the plurality of hinge knuckles including an aperture extending there through;
• and
• at least one coupling feature positioned on the first surface, adjacent the plurality of hinge knuckles.

A method of assembling a modular structure including a first module and a second module, the method comprising:

• positioning the first module and second module adjacent one another;
• articulating at least one floor component from the second module;
• articulating a first sidewall component and a second sidewall component from the second module such that the first sidewall component and the second sidewall component are perpendicularly positioned relative to the at least one floor component of the second module;
• articulating at least one roof component of the second module to be positioned over the first sidewall component and the second sidewall component of the second module.
