I'm moving this weekend. I'm moving in with a roommate and a small extra bedroom. I want to claim a space for building a kit over the winter, and for repairs in general.

How large of a surface do you need to build a (.40, maybe .60 size) kit?

When building a kit, are you ever able to clear off the surface at the end of a day/night, or do you leave it out once you start, until you are finished (i.e. can this be my desk for schoolwork, too)?

Thanks.
