The yurt is about four or five years old and is 24 feet in diameter but is like new and was manufactured by Colorado Yurts. It has: Tall Walls; Opening Dome Skylight; Three Windows; Three Double French Door Sets (4' wide each set); Roof and Wall Insulation; Wind/Earthquake Bracing (@ the wall studs); Ceiling Fan with remote control switch + wall switch and electrical outlet; Plywood Floor over Floor Joists with Insulation and moisture barrier); Brand New Upgrade Exterior Wall & Roof Fabric (has not been used/installed yet......the new fabric meets California standards for fire resistance - I have the specs on this); Stamped Engineering Calculations; Hung Fabric all around on the inside covering the wall lattice.
