Benches and arbors are ideal for relaxing and for special, romantic or contemplative moments. This project is easy to build and can be completed in about three days. The earthbag bench and arbor are affordable, easy to build and easy on the environment. The bench consists of a stone foundation and plastered earthbags, which are polypropylene rice bags filled with gravel. After you’ve gained experience building this small bench, you’ll be ready to take on larger earthbag building projects.
