No house can begin to be built without the proper foundation and these awesome ziggurat foundations are no exception. The weight of our house will be carried by wood beams that will then transfer the load into the plywood foundations. Our earth team came up with this brilliant design as a way to continue to meet our goal of mitigating the overall cost of our house. Because we chose to move away from the more common and expensive metal foundations we needed a way to spread the loads into the ground with out damaging any of that pristine D.C. sod.
