If you want bamboos to build with, your choices will be affected by your goals & your environment.
Good drainage is important.
Size (diameter) and strength do not always go hand in hand. Some species with smaller diameter canes are stronger and more durable than other species with larger diameter canes.
If you plan on building with bamboo you will likely want several diameter sizes to use.
Whatever strategy you develop, you will need to account for maintenance. Keeping the clumps thinned out (removing older and unwanted growth) will encourage straighter canes for construction and easier harvesting.
Ideally, canes for construction are left uncut in the grove for a minimum of 3-5 years before harvesting. This allows the canes which, when new, are full of sugars, water and starch, time to lignify & harden.
We’re breaking this down into two categories.
One is for the material that you would build structures meant to last a generation or more.
The second category is for building less permanent structures, furniture, floor boards, wall panels or crafts.
