Various Compost Toilet Design and Builds The attached photo shows our most recent compost toilet design and build. This photo is from 2009 when the building was under construction. It is now in use. You can see the twin chamber system clearly in this photo. The design drawings show early designs of compost toilets including an accessible loo, although funding did not allow this to be built.
