Method of basement construction

A method of constructing an inhabitable underground structure comprising the steps:

• creating a cutout in the earth at a desired location to generally match a desired shape of an interior of the underground structure;
• applying a reinforcement structure to the cutout, the reinforcement structure having one or more transitions comprising concave curvatures for connecting a plurality of walls of the reinforcement structure to a bottom of the reinforcement structure;
• applying shotcrete over the reinforcement structure to create a monolithic underground structure;
• using a top side of the monolithic underground structure as a foundation to support an above ground structure;
• and
• placing a plurality of floor beams across a floor of the underground structure by mounting the plurality of floor beams above a bottom of the underground structure such that a resulting finished floor of the underground structure is spaced apart from the bottom of the underground structure to allow for draining of moisture between the finished floor and the bottom of the monolithic structure.
