Almost. I have converted an old falling down cowshed into my house. Involved everything from underpinning walls, demolition and rebuilding of rubble filled stone walls, roofing with 2 inch thick sandstone roofing slates, wiring, plumbing etc, as well as processing all the timber and making the doors, windows and kitchen units on site. During the build I was living in the shell. In the end the process took me about 10 years. 🙂
I was lucky in that I was working on site for the day job (farming) so could do a bit of work on the house whenever. It was certainly tough going in the early years, living in a building site, but the money saved, means I have a house, exactly as I want it, and no mortgage. 😉
PS I didn’t actually do everything on the house as I did get a man in to lay a carpet in the bedroom.
