“Round Timberframing. Harvesting trees from the site where we are building and using the trees as round structural members is ideal. Certainly this is time and labor intensive, although structurally, round timbers outperform milled timbers of the same dimension.

We reported on their adobe retreat center yesterday. Now New Life Foundation is building puddled adobe housing at their center in Chiang Rai, Thailand. This type of construction receives very little attention even though it’s one of the simplest, lowest cost building methods and has been around thousands of years. It’s believed the oldest house in the US — pre-Spanish — was built with puddled adobe. Among other things, puddled adobe would make good interior walls with adequate framing at doors.
