It is heavier than wood and has much less tensile (?) strength. It doesn't rot, splitter, does fade but no staining required. I don't think you could really build much out of it other than a deck or platter....
I built a rather large deck on the back of my house with it: probably 30x12+ with multiple 4 levels and stairs. It is great for a top deck material but has to use more re-enforcement to do the job than just wood alone.
