Are you planning to use your Yurt as a four-season dwelling? Basically – are you planning to live in it permanently? If so - snow / wind rating combined with insulation
is going to dictate the nature of your Yurt. For permanent Yurts, we always recommend a Durolast
Roof ™ and deluxe snow / wind kit (vertical supports at every rafter with structural brackets at every frame point). Rafter and base blocking will increase the snow rating even further if necessary.
Have you given any thought to your environmental controls (Heat / AC)? Insulation
will be a given if you plan to heat the Yurt.
Do you have any plans for the platform the Yurt will sit on? An insulated platform is also necessary if you plan to heat.
A 20’ or 21’ diameter is quite small for a family of four, but that is certainly personnel preference. A sleeping loft is possible in a 24’ Yurt with 7’ walls – which could help meet your space requirements.

P.S. We have lots of Yurts in Ontario. Mostly surrounding Toronto and north.
