Why is the ISS built out of tube chambers instead of spherical chambers?

Wouldn't spheres allow us to build larger modules without increasing the weight?

I believe it is limited by the size and shape of the payload container on the lift craft.

The shuttle's cargo bay is only so wide and long. A spherical module is more efficient in space, but less efficient to lift there.
