Farewell to The 200

The 200 was a special project developed as part of our earthen building technology initiative. It was, in fact, a 100% earthen building constructed with cement stabilized compressed earth blocks. Built as part of a workshop exercise, it featured the following initiatives:

  • 10 inch thick compressed earth block wall sections
  • an experimental ventilated cavity wall section
  • a compressed earth block barrel vault roof
  • traditional lime plaster
  • rubble trench foundation

The 200 opened up plenty of opportunities to learn and experiment with earthen building assembly, block production and construction sequencing. It also gave us a rare opportunity to log data over an extended period of time to track building performance. I was successful in logging data over four seasons both inside and outside for comparative analysis. I will update this post with that data shortly. In the meantime, adios 200!
