Abstract: A cubicle unit is constructed in a standard frame size to accommodate transportation and re-fitting into a building structure. The cubicle may be fitted with various apparatus to fit the needs of the owner/occupant. The cubicle can be pre-fabricated in a controlled environment, warehoused, and shipped independent of the overall building structure. Installation of the cubicle may be achieved by aligning the cubicle with the building mounted receiver track. The receiver is connected to the building securely by means of mechanical fastening. The cubicle may securely fasten mechanically to the receiver. Cubicle joints may be installed between cubicle bays that cannot be set in place without a gap. Additionally interior and exterior facades may be mounted to the structure to enclose the space.
