bamboo is a a short-term structural material, by that I mean that it will decay rapidly over time, so you can never build anything semi-permanent with it, especially in a hot humid environ. Having siad that it is a magnificient building material becasue of it's inherent strength, lightness and felxibility in wind. You might try to google for some Papua New Guinean 'Sky-Huts' (my own name for them. the PNG guys build amasing tall airy structures, sometimes using bamboo. I would LOVE to build one of them sometime; 40 ft in the air, think of the view!
