Different options for khana (small yurts)

[Yurts_latvia]

Hello again

I'm building a few different 14 foot yurts to get started in yurt building, trying out different materials and techniques. Walls are 160cm high.

I followed advice to use 8mm x 40mm (1/4" x 1 1/2") slats for my first yurt.

They're working fine but have quite a lot of flex in them - now I also want build yurts that can take the weight of snow.

I like working with the thin, flexible slats and wondered if I increase my roof pole number (from 32 to 40), then I will have to make a lattice that's correspondingly tighter together, with more cross-over points. (I could increase cross overs on each lath from 7 to 9)

Is adding more cross-over points a good enough way to strengthen a wall, or would it be better to go for sturdier timber?

I also have the option of 15mm x 35mm laths, but soft wood is all that's available.

Thanks for any input!
