STANDARD
SPECIFICATIONS FOR OUR BALI HOMES AND GAZEBOS
Our homes and gazebos
are prefabricated strictly in accordance with our standard specifications,
uisng the best materials avialable, fit for its particular purpose.
We will not depart from these specifications unless a client requests us
to do so (and will accept the impact if this turns out to have a negative
influence on the project).
All
tropical hardwood is obtained from sustainable legal plantations monitored
by the Indonesian Government. Unless otherwise noted the wood which is
used for our prefab homes is first class Bangkirai (Shorea Laevis), or
Merbau (Intsia Bijuga). These are two of the four Indonesian wood species
which are not susceptible to termite attacks (the other two species are
Bojonegoro Teak and Iron wood). In order to protect its tropical forests
the Indonesian Government imposed a ban on the use and export of Iron wood
since November 2007, hence this wood cannot longer be supplied.

<here> for the latest about the new import
regulations of tropical hardwood into the USA.
A full set
of drawings + all necessary technical information will be submitted which
may be required for the application of the building permit to a County or
other Governmental authority.
Export
papers will be accompanied by a Government signed certificate, letter or
otherwise showing that the wood used originates from a legal timber
felling concession. Our prices include a contribution for
the Indonesian reforestation program.
As you might imagine, a hardwood home
is similar to a car in that there are many options which will affect the
price. The price range is due to many factors including:
 | Efficiency, since our designs
utilizes standard lumber sizes (this is in particular an important
factor in designing a GREEN home (ECO home) as inefficiency = waste) |
| Wood choices for sidings (interior
and exterior) and flooring |
| Window choices, size and number |
| Door choices, size and number |
| Insulation for walls, ceilings,
etc. (above and beyond any specific requirements that Counties may
impose) |
| Cabinetry choices |
Since early 2010
we have discarded any use of Camphor wood since this wood does not longer
comply with our high demands. We replaced Camphor wood with Nyatoh wood
(also called "Chinese Teak"). Though slightly more expensive than Camphor
wood the advantages are apparent. We now only use Bangkirai (for all
structural works, like beams, columns, trusses) and Merbau or Nyatoh wood for flooring, sidings, doors and
windows.
"One cannot buy a Mercedes for the price
of a Volkswagen". We produce the Mercedes but unfortunately not for the
price of a Volkswagen.
