If someone tells me we can build a shed, I'm going to ask who's land are we building it on, who's paying for it, what zoning/permitting laws apply, who's going to own it (form an LLC or a -corp with shares). The kind of wood and the type of nails aren't even worth wasting time discussing until we've answered those questions first.
