"Guadua angustifolia is a Neotropical genus of thorny, clumping bamboo in the grass family, ranging from moderate to very large species."*
So this is a South American native, unlike Bambusa which is native to Southeast Asia. It does appear to be recognized for it's strength if you are growing the angustifolia species.
Plant identification is not my strong suit and bamboos need to be carefully identified. There are people out there with the skill and I admire them greatly. If I was even remotely in the right climate, I would certainly be interested in growing this plant. I have admired bamboo ever since spending some time in Japan. They have many experts in which bamboo variety to use for what task, and it is amazing what it can be used for.
Finding good information on safe, reliable techniques for building with bamboo is still difficult. It has often been looked down on as it tends not to last as long as bricks. That said, it is lightweight, can flex in earthquakes and bad weather, and that can make it a much better option than bricks in certain places. If you are in an area where you can grow your own, the shorter lifespan may not be as much of a detriment as some people might think or suggest.
