Build space.
Built both wings and my fuselage in a fourteen ft. single wide mobile home. Had to cut the end off the bar between the kitchen and living room area in order to squeeze by sideways to get from the front door to the bedroom during the fuselage stage.
Had room for a workbench and had all the comforts of home, so to speak. Course, you didn't dare walk around bare foot because of all the aluminum curlicues, shavings and drilled out rivets in the carpet!!!!!
Eventially, life got better. Got a hangar, new wife and built a new house! Ended up putting the wife to work, replacing the carpet in the mobile home and renting it out, both of which helps buy gas!
Where there's a will, there's a way!
