This plan assumes a rectangle shape when complete. The old entry doors form a new entry platform for the unit as transition extension of the space. An alternative is to use the cargo doors as an extension of the structure and suspend an entry floor from the doors similar to the extension of the living area. (not shown)
The bath is considered to be a total wet area with the floor being a duckboard floor with drainage below to keep feet dry and allow for easy cleanup.
. The table is an extension table that attaches to the wall and stores expansion leaves in the wall storage cabinet. This table can be moved to any place inside the unit.
.
The bed is on a cable suspension system that uses a rail guide on the wall and allows the space underneath to be expanded living area when the bed is raised to the ceiling. The bed base uses lights to help increase functionality. A full height curtain adds to the privacy of the sleeping area.
.
If needed floors are removed and new flooring is installed with new insulation and a (sealed) metal protection skin added underneath the unit to allow for better thermal performance.
.
The kitchen is a two cabinet design with one being wet and the other dry. The wet cabinet component has the sink and dishwasher option in it, along with vented cooktop cooking. The other has all the dry storage and unvented cooking (ovens). When opened they form a galley arrangement with the possibility of the Dry component having a pass-through feature.

This layout is based on the idea of outdoor patio living on two levels. One on the main and another raised semi-private and all private spaces. The 2nd level enclosed space is thought to be created with Structural Insulated Panels (SIP) wall, floor and roof panels. These are shipped inside the single container and installed onsite. They are pre-finished and ready to snap together and connect to the container with hand tools. .
Sitework consists of 10 post foundations. One of them is a freestanding pole foundation which requires some depth to resist overturning. All the others are simple gravity pads to take the unit loads. There are integrated support poles that attach to the sides of the units to support the upper shade tension structure.
The stairs are modular preconstructed blocks that ship inside the container and are attached to the deck.
The deck could be shipped in the containers and assembled after arrival, but it would be faster if they were already installed and ready to receive the units.
Units connect to utilities for Water, Power and Sewer with quick connections.

Openings in steel containers requires some closure strips to allow for proper sealing against air and water infiltration. These are details designed for vertical walls.

Cabinet modules mounted on guide rails to help make moving the heavy components easier with either low-friction bearings or motorized assistance.
.
Cabinet modules may have other automation and sensing technology to assist in configuration and location, Such as adjacency sensors for access, lighting and operation.

These layouts allow for a central utility run and access with a common orientation and redundant privacy. This layout is optimized for a N-S oriented street frontage.

All of these use two 20' units with three variations. that could fit on a 75' wide lot.
This layout optimizes a central location for all the utilities for all the units. It does mean a lot of services come together in a single location, but it also means there is less risk for random hits on services that can be protected in a concrete distribution cluster.
