By utilizing the SIP - Structural Insulated Panel
building system, we provide a mobile green building system
that is energy efficient, expandable, and offers a cost
SIP Home .
GEMDUS Home Systems are the
most energy efficient mobile building systems available on
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
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 construction home.
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 $ 80,000.
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.
By utilizing our
SIP 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 and
other power systems. GEMDUS offerings in the future will be
with solar systems.
If the GEMDUS is not quite what you are looking for, but
you want to stay green, Green Sense Builder offers a
variety of individual
services from design conception to complete SIP Home
Packages. We pride ourselves in the fact that our
clients are completely satisfied with our personalized
service and commitment to excellence.
Every one of our homes qualifies to go
Energy Star Program and can be rated upon completion
for the Energy Star "Seal
of Approval". Not only will the home be more
energy efficient and save the homeowner money over the
life of the home, but the home's resale value is
The GEMDUS and our SIP Systems do not require highly
skilled tradesman 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.
