Progress on Staircase

Our staircase to the apartment in the guesthouse is getting it's final touches done on it. Our inventory of bamboo consists of 2" to 3" diameter stocks of bamboo. Therefore we designed the staircase structure as a truss, and extended the webbing beyond the supports to form the treads and risers. We made a sample of this design several weeks ago, and it had three treads. To increase the strength we added more diagonal crossing to distribute the load for the people walking on the stairs.
