ECO cottages

Our ECO 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. Roofs are insulated in a similar way as the sidings. 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.

Materials used

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. Nyatoh can be substituted by Bangkirai against a variation order. Trusses are made from Nyatoh as well. 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 or wooden shingles can be used as alternative against a variation order. 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 (unlike our standard units which have interior and exterior Keruwing siding boards).

Due to the fact that our ECO cottages have all these extra built-in features the units are approximately 25% to 35% 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.
