The third case holds that architecture is not needed but that engineers must think about how to make the structure beautiful. The suspension bridge can be viewed as an upside-down arch in tension with only the towers in compression. These cables are then spread into the rock or concrete to more evenly distribute the weight. Example treehouse bridges Shepfarm treehouse - well documented cable bridge with a support frame at one end and a treehouse at the other.
