I want to understand why we do not build space stations in a similar way that we build a home, piece by piece. Instead we construct modules on the ground and fly them up. Are there some technical limitations other than money that make this impossible?
Why don't we fly up raw materials, prefabbed metal panels, structural steel and any other material and slowly construct a space station that is suitable for somewhat normal living, normal sized rooms, ceiling heights, etc.?
I'm wondering if any plans exist or working groups are exploring this idea. Or is it a technical limitation, for example: not being able to ensure a complete seal between the exterior pieces?
Is what I am wondering clear?
