once you start building it, you will soon realise it needs bracing. i'll give you till the 3rd lift at most
Its only a transom that fits on the ledger. You have to have ledger bracing how are you going to keep the standards upright otherwise. Madness not to include ledger bracing, I would stand well back if you dont put them in, it will look **** as well, none of these transoms can hit the building so you are relying on ties only to bubble the job!!! dont think so!!!
