Ok so I've been speaking to the my work buddies who im building this with, and the saw mill want quite a lot of cash for the 6x10'!

We are looking to go with the adding the extra bent option,

So I've redrawn it all up with resized braces and everything drawn as it will be built

All posts and beams are 6"x6" and the floor joists are 8"x2"

Let me know what you think of the plan,

Thanks!
