Single garage near to (or attached to) the house is do-able, especially as some of the jobs can easily be brought into the warm in winter (permission pending from other house users). Before the bodywork and wheels are fitted there is a lot more space around the chassis, see my project here. Once wheels and bodywork are on it's a bit tighter, make sure you have somewhere to put the front and rear clams after this stage, or you will need to work outside. Put some foam over the chassis vertical door plates (and wheel studs) otherwise you'll be forever banging/catching yourself on those every time you squeeze past. When putting engine in, watch the ceiling.....
