This is a high performance build, and built for the weather found in the Northern US. This unit is not built on wheels it is built on a concrete slab that will be moved with the unit. 2x6 walls with R-21 Insulation and R-49 Insulation in the ceiling. I am a full service licensed contractor in the state of Washington and plan to do ground preparation and build a deck if you would like. Please contact me for more information.
