Teak faced ply that isn't really Teak faced ply.

That's a v good summary of the issues around bamboo board production, however the industry's developed massively since the 70's. If its worth engineering v small section softwoods into only slightly larger components (I'm not talking gluelam beams) then at some point the production of boards & other stock that shares most of the properties of increasingly rare hardwoods must become economically viable? Fingers crossed.

I have several pieces of bathroom furniture from The Futon Company that are made of bamboo. Larger boards and sections are made up by laminating the smaller sections ( around 10 X 20 mm) that are naturally available. The furniture is inexpensive, and stands up well to use in a bathroom, where it is often wet and high humidity.

I also have several chopping boards made of bamboo using similar techniques - they are tougher than equivalent hardwood boards.

The use of bamboo in furniture and architectural settings is well-established, especially in the far East.
