agreed. it sounds great to isolate so you can "get stuff done with no interruptions", but I think in reality the time is more productive with a low level of background noise and activity by others. not drawing you attention away from the task, but enhancing it with the occasional "honey, you've been at it so long I thought you might be getting hungry. I made my world famous snicker-mores and here's a coffee to wash them down" does wonders for the morale.
it can also make your hobby more acceptable to others around you because they begin to understand the dedication which goes into building something with your hands.
having the workbench & project "at the ready", tools out, parts prepared for the next step, can invite production when a brief or odd moment of unpredicted time avails itself.
