would you rather live in a house without windows or in a house without roof if you HAD to?
It's a house which means it has multiple stories. I would pick the open roof and then just use the Downstairs part. That way I would be protected from Rain, Snow, Sun and Wind whereas I would still be affected by them if I had no windows. If I could board up all my windows or pay for new ones I would pick the Windowless house and replacing or boarding up a roof would be much more expensive.
I could live without a roof.... my binoculars have to point somewhere!
