The one and only viable location for this "orbital shipyard" is within
the Earth-moon L1 (aka Selene L1), because that's where the most
volumetric tonnage can safely coexist with the least amount of applied
energy.


The additional energy to go to L1 is a big negative to go there. L1 is
closer to the moon than earth, so it is also outside the protection of
the van Allen radiation belts.
