If you get the chance to move out, consider getting a Passive House, where it has super-thick insulation and is hermetically sealed. You wouldn't have to worry about frozen pipes in that kind of setup.
Shields, check. Energy weapons, check. Now we just need a viable interstellar drive, and an energy source to power it all.
No, what we need is a strong hull that can withstand all the micro-meteoriods hitting it at 27,000+ mph.
I recommend getting a General Products #2 hull.
Only through hard work and perseverance can one truly suffer.
