Shell Cost for a Site Built unit per Saylor System to compare to the Patent Process
Based upon the Majestic Model -- a 1232 Sq Ft. 3 bd 2ba unit
The
Saylor compute program CD allows for complete costing of any floor
plan. This cost sheet is a comparison with the Patent Process
shown on the previous page. The main difference between the two shell costs
is that the wood frame requires a 2 x 6 wall to get even close to
the R-40.37 insulation factor of the Patent process, while the Patent
process only requires a standard 5-1/4 inch thick wall. The
comparison also indicates a savings of $30,917.31 for the patent
process for the Shell. This does not include the other cost
savings in overhead, manufacturing, labor, site savings, and other such
benefits. The amenities such a appliances, furnace, water heater,
etc. cost as much or many times more than the Shell cost, paticularly
with the Patent process.
