fire is a consideration that everyone with a nipa hut needs to be aware of in just the same way as owners of thatched houses in the uk have to be aware..our kitchen is all cement construction and away from the main house and no fires are allowed anywhere near the property.. we have fire alarms installed in every room.
never heard of a native house or a resort building burning down so it must be quite rare.
there are water systems available that can be fitted to protect the roof and keep it wet if required..
