Functional modular building cartridges and methods

A modular structure, comprising:

• a systems cartridge that is configured to provide a plurality of services for the modular structure;
• a spine cartridge that is configured to be attached to a top of or a bottom of the systems cartridge, wherein the spine cartridge comprises a plurality of conduits for conveying the plurality of services from the systems cartridge to a plurality of access points in the modular structure;
• and
• a planar wall comprising at least one of a pre-plumbed water line, a pre-wired electrical line, a pre-wired network connection line, and a pre-fixed air duct, wherein the planar wall is configured to form a portion of a room or a portion of a perimeter of the modular structure,
• wherein the systems cartridge, the planar wall, and the spine cartridge are prefabricated before the systems cartridge is attached to the spine cartridge at an on-site location.

A method of assembling a modular structure, comprising:

• placing a systems cartridge on a foundation, wherein the systems cartridge is configured to provide a plurality of services for the modular structure;
• placing a plurality of cartridges on the foundation, wherein the plurality of cartridges comprises at least one of a bedroom cartridge, a kitchen cartridge, a bathroom cartridge, an entry cartridge, and a closet cartridge;
• and
• attaching a spine cartridge on top of a portion of the systems cartridge, wherein the spine cartridge comprises a plurality of conduits for conveying the plurality of services from the systems cartridge to a plurality of access points in the modular structure,
• wherein the systems cartridge, the plurality of cartridges, and the spine cartridge are prefabricated at an off-site location, and the systems cartridge is attached to the spine cartridge at an on-site location for the foundation.
