Subject: Great big boat shaped house, perfect in case of major flooding
hey Dale, check these out. Boat shaped house house. pretty handy in times of deluge
Those houses are diffusion markers between Southest Asia and South America, in less extreme forms and considered to be about 500BC: they are depicted on pottery of both regions. They are called saddle-roofed huts. and they are usualy built raised up on piers or stilts.
They are built with some sophisticated carpentry techniques and many of the same techniques of making the framework and fitting pieces as would be used in making actual ships: and I had even seen where it had been suggested that the houses were made in imitation of real ships hauled up on shore and converted into houses (something we find otherwise in places as far apart as Viking territories and Polynesia). It would be interesting to get measurements of these houses and see if they could be built in sizes applicable to the sailing ships that there must have once been in old Sundaland.Similar boat-shaped buildings exist in New Guinea.

Re: great big boat shaped house, perfect in case of major flooding
Batak Toba culture centres around Lake Toba and the sacred island of Samosir that lies within it. Jabu is the Toba language word for rumah adat. The houses are made up of three sections. A substructure of large wooden pillars resting on flat stones (or concrete nowadays) protects the structure from rising damp. Some of these pillars support longitudinal beams known as labe-labe, which run the length of the house at head height to carry the massive roof. Other pillars carry two large beams with carved singa heads which, with two lateral beams mortised into them, form a great ring beam bearing the small living area. The substructure is strengthened by beams mortised into the piles which double as night stalls for cattle. Walls are lightweight and lean outwards and provide additional stability to the structure. The wall and the wall plate supporting the rafters hang from the labe-labe with rattan cord, while the base of the wall sits on the ring beam. The rafters spring from the wall plate and are angled outwards producing the roof curve. In lieu of horizontal bracing battens, diagonal ties—running from the middle of the labe-labe to the gable ends—provide reinforcement.
The large steeply-pitched saddle back roof dominates the structure. The roofs are traditionally thatched, and with no internal roof trusses they provide a large internal space. Sharply projected triangular eaves and gables overlap all around the substructure. The front gable extends further than the rear gable and is finely carved and painted with motifs of suns, starts, cockerels, and geometric motifs in red, white, and black. The rear gable remains plain.
