I interned for three weeks on the original global build in Buffalo Wyoming. Three years ago my wife and I pounded our first tire for our two bedroom global adaption. We finished the tires this past May, and in a few days we’ll have finished laying the can wall form for the bond beam.

The footings are dug, and rebar is in place. We are building in Northeast Oklahoma where we experience fairly cold winters, and extreme heat summers with high humidity. We average well over 45 inches of rain per year, with a couple feet of snow and ice in the winters.

We’ve changed some things, like no greywater capture in the greenhouse, to avoid added humidity, and no need for water to flush as we use a composting toilet system. We also changed the front face to vertical and are using mono pitched trusses where we will blow in insulation as well as have sheet insulation under the roof material.

Instead of purchasing cisterns we built two can wall cisterns that combined will hold almost 5,000 gallons, and we built a third cistern to catch water off our barn for outside water usage.

It took 2.5 years for the two of us to finish the tire wall, but we finished this past May. Summers in Oklahoma are too dry and hot so we don’t like to do big concrete work during that time. Currently we are finishing the can wall forms for the bond beam. We should be ready to pour in a week.

We are having some difficulties figuring out exactly how we are going to “cap” the can wall cisterns, and they also still require plastering and the floors poured. We also have the last section of thermal wrap/vapor barrier to add before complete burial. We looked at trusses last week, and should be ready to pull the trigger on those in about a month.

Thanks for getting this information out! So many people are out there doing this on their own with no more information than what they get over the internet.
