I would like to know more reasoning behind choosing a frame without diagonals. I have had to repair many old garages and shacks which had wooden frame but lacked diagonals. Often we had to push them upright and brace the frame with diagonals to avoid problems in the future.

A cube-like building frame without diagonals or shear walls is unstable and does not sound so strong or resilient at all.

in a typical wood-frame wall, it's (usually) plywood nailed to the studs that acts to resist shear forces. you shouldn't need diagonal cross-members, unless there's not enough structural plywood cladding or not enough studding.
