The big thing with building a car like this is the ability to keep moving forwards. There WILL be times when you don't feel like you're getting anywhere but being able to go to it and do something, even if it's just a little job, keeps it moving and prevents it from becoming a part built project for sale. I haven't always managed this - I've built two Robin Hoods and am coming to the end (I hope) of a major rebuild of a GTM Coupe but in between these there was an SPD200 that I bought part built and sold with not much done to it plus a Focos that I sold recently as a change of job immediately followed by the landlord not renewing the lease on our unit meant I didn't realistically have the time or the space to put it together. I did meet a guy who built a locost chassis in his cellar. He'd measured the doorway to make sure he could get it out when he got to a certain point so he knew he wasn't going to be one of "those" people who build something they can't get out of the workshop. Unfortunately he hadn't considered that once it was out of the cellar there was another door before the door out of the house and it was slightly narrower. He became one of "those" people anyway. Someone in the Robin Hood owners Club built their car in a static caravan that they had bought for scrap and put in the back garden. Come the day to get the rolling car out they cut the front end off the caravan to roll the car out (and subsequently cut the caravan up to dispose of it).
