cottages are specially designed to protect the environment. In fact you
may call it Green houses. Like all our other
houses and gazebos, all timber used is obtained from sustainable and
well controlled plantations. A contribution is paid for Indonesia's
reforestation plan. The designs are adapted to the environmental
circumstances. All walls are sandwich walls so that insulation materials
can be applied between the siding boards. The roof will be insulated as
well and we offer the possibility that solar panels can be installed.
Since low mass constructions heavily contribute to a fast temperature
change inside a building we use 25 mm thick sidings on each side of a 60
mm wide framework which is filled with insulation material (polystyrene
foam). The delay rate for such structure is approximately 3 hours. Solar
radiation intensity is highest on horizontal surfaces and lowest on
vertical surfaces. Our roofs are shaped such that optimum air flow will
occur. Roof decking are Bali style terracotta tiles. Thatch would be the
better insulation option, however, we consider this not ECO friendly due
to the fact that thatch needs to be replaced every 6 to 7 years. We use Nyatoh wood for the sidings and flooring.
Despite the fact that we use expensive timbers, stainless steel and Cetol ® coating we succeeded in
keeping the price ECOnomically low, due to
our long experience in timber prefab structures.
All exterior and interior boards
on the siding frames are made from 25 mm thick Nyatoh boards connected by
T&G and hidden screws. The exterior boards have a rain water run-off
sill. All floors from 25 mm thick Nyatoh boards, connected by T&G with
hidden screws. The structure, (main floor beams, sub floor beams and columns) are made from solid
Nyatoh can be substituted by the termite resistant Bangkirai against a variation order. Trusses are made from
Camphor. All windows and door panes have insulated glass. In the event that door
and/or window panes become too large we use tempered insulated glass.
Fixtures (threads, nuts, washers and screws) are stainless steel grade
304. Not one nail will be used. Window and roof hardware from stainless
steel. Roof covering from Balinese terracotta tiles, however, thatch (see
remark above about life time) or
wooden shingles can be used as alternative against a variation order. We
also provide an option whereas you install the roof decking at your end
by yourself. The cottages have
raised floors (about 40 cm above natural grade) as to prevent creepy
crawlers from entering the house. The exterior and interior of the cottage
is protected with Cetol ®, world's foremost environmental friendly protective coating. We
guarantee a maintenance free period for the exterior of 30 months in the most aggressive
environment (close to open sea with salty spray). Alternatively French
Polishing can be used for the interior against a variation order (refer to
the French Polishing page)
We supply all assembly drawings which include the
drawings for plumbing and electrical lines.
A question often raised: "Is there any difference
between our standard houses, villas or custom made houses and our ECO
cottages?" The simple answer is "yes, there is". Our
standard houses are being prefabricated and assembled exactly in the same
way as the ECO cottages, except that for the ECO cottages facilities are provided for solar
panels, roof and siding insulation is included, glass is always insulated
glass and sidings are made from Nyatoh, a very stable and flexible wood
Due to the fact that our ECO cottages have all these extra
built-in features the units are approximately 30% higher in price compared
to our basic standard system for the same units.
We may consider this
the client’s contribution to a better protected environment.
