I believe in ideal conditions, even without CO2 doping, bamboo can grow at something like a foot a day. And stone bamboo is routinely used as scaffolding around buildings in parts of Asia. Bamboo also tends to flower and die off every X years. But genetic engineering might be able to help with that. I think genetic engineering which will specify the shape of a house is quite for away, far more away then the "fix" for the dye off. But these willow houses are shaped by grafting and bending and I think you can do the same with bamboo. But I'm not sure, bamboo is a grass so maybe you can't.
