Any way you can make a little place out in the back yard or at a local park? Blankets and just the stuff you want to work on? Or you could try the library or a local restaurant if you have a laptop and are using internet. Otherwise I'd just work to get up early enough so you have an hour or so in the kitchen/living room undisturbed before people get up?
I'd figure out a way to think about the project whether you are working on it or not. I'm working on a project and HAD to get up at 4:30 yesterday morning to check some things out, my curiosity was just so great

Really liking what you are working on helps a lot with both concentration and doing well/learning a lot.
