What is a
GEMDUS is a Green Expandable Mobile Dwelling Unit
System, that is sold in 8' wide by 17' 1" long, 136.67
sq ft units.
Why choose a
GEMDUS = quick to build. If you need a quick build of an
energy efficient low cost custom home, without the stigma of
a manufactured home, turn-key, in 3 months or less, the
GEMDUS is the answer. Each section of the GEMDUS is designed
to be placed on a permanent foundation. Engineering for the specific site
(i.e. wind shear, seismic, soil loading) should be done and
the home is permitted through the building department.
Several models of the GEMDUS are available in the GEMDUS
Floor Plans page. The design is done so that each section
can be highway towed behind a minimum half ton pickup,
placed at the site onto the foundation, and each section
bolted together. The roof system will take a little assembly
over the cube. The GEMDUS has a 6-1/2" SIP floor, and 6-1/2"
SIP wall system. The roof system is a flat 8-1/2" SIP with
a stick framed rafter over it to get the pitch. LVL's are
placed inside the 8-1/2" SIP for support over open areas.
The structure will require posts for support where open
areas are maintained. See the GEMDUS-S2 and the
GEMDUS-S3 models as an example of post placement in an open
configuration. Complete construction drawings for each
GEMDUS will be engineered and made available to the building
department so the home can be permitted.
The truss rafter pitched roof system is open to allow for
electric, PEX, and HVAC. The units need to be placed on a
raised foundation for septic runs. There will need
to be correspondence with the building department to get them
to understand how the house will be delivered, and how inspection(s)
can be done. The GEMDUS will qualify for and look like a standard
Give the GEMDUS-A, -B, and -C a look to get the general idea
of the Expandable portion of the GEMDUS. GEMDUS-A could be
sold as a small self-contained unit, then another GEMDUS
bought to get to -B, and another to get to -C. Doors,
windows, sliders, and even deck portions are planned to be
re-used as each option is expanded.
GEMDUS will vary depending on location. At present we can
offer the 820 sq ft GEMDUS-4 for
Please remember that the GEMDUS is not a manufactured
home. The trailer goes back to the factory. The GEMDUS can
be thought of as a real large 2x4. You will need 3 pieces to put
together, and get to a 410 sq ft home.
The desired outcome of the purchase of a GEMDUS is that the
owner gets a section, installs it, and then gets another
section when ready. The assembly time of the sections is
to be less than a day for two units. The assembly of the roof system is
planned to take two days maximum for the three unit system.
The foundation setup will depend on the build method and
could take as long as a week. Time must be allowed for
building department inspections. The GEMDUS system should
provide the buyer with a home ready for occupancy in
approximately one month.

System we provide the most modern,
maintenance free, energy
efficient building systems on the market today with
up-to-date alternative energy systems in solar, wind

future will be with solar systems.

to erect it. This system allows the contractor
or owner builder to complete the project in less
time than a conventional stick-frame building system,
and is designed to function for the clients lifestyle
and offers great curb appeal, while maintaining
a high resale value.
