Generally, yurts can be raised on any flat surface. If you do not have much budget for the platform, you can have a simple wood platform (drawings are available from us) directly on the ground or at a slightly elevated position for drainage purposes. An advantage of this type of platform is that it provides natural insulation as there is no space between your yurt and the ground. A disadvantage is that you may need to replace parts of the platform in 5-10 years, and it is prone to flood risk if there is such risk at your location.
If your land has a slope or you want a more permanent solution, an elevated platform can be built using various materials such as wood, OSB, and sip panels. Local contractors are usually able to build elevated platforms.
