Architect Tom Ward chose rammed earth for its sustainability and connection to his Wyoming home's stunning locale. Built from dirt on site, the striations abstract the undulating butte where the house rests. “You have to appreciate what they did,” said a judge.
The area's seismic activity nearly nixed the wall, however. So Ward and his team developed a way to overcome instability. “Post-tensioned rammed earth is a technique we patented to provide strength to the system and meet earthquake codes,” Ward explains. The method also stands up to snow loads and gale winds. Said our judges: “It's a great way to solve the issue of rammed earth's lack of strength on lateral loads.”
