I wouldn't call it a daft idea, bamboo can be a royal pain in the arse if you don't look after it. It tends to take over when you turn your back on it. It would all depend on the area you have to grow it in, and the time you will have to grow it before using it. On a plus point its been used for construction since before records began, so its defiantly viable now.

read red mars, its even used by the first colonists.
