Adding wood to a lattice style yurt will only weaken the structure. They are designed to flex and wood sides or roof are rigid. They also aren't designed for that kind of weight. A well manufactured yurt is typically rated for winds up to 120 mph. You will need to go with a top manufacturer, Colorado Yurts are always too of my recommendations for quality, engineering, and stellar customer support. The engineering portion is important if you want to permit. To get insurance, most carriers want permits and engineering. Aloha,
