Well, we have 2 little houses. I have my little yellow house that is 200 sq. ft that I call my playhouse. Since it is small, any repairs would be small, easily manageable jobs. My fiance did the repairs on my playhouse and I helped him and watched so I will know how it works and how to fix it. It is important to me to learn everything about fixing my little house from the electrical, plumbing, etc.My father was a carpenter so I do know some things and am always wanting to learn more. I also worked as a roofer after a recent hurricane so I know how to do that also.
I want to be self sufficient when it comes to my playhouse. I plan on learning to do tile work so I can do my kitchen counters and I have new light fixtures to put up and siding that I want to do redo. That's one of the big appeals to me about my playhouse. I can learn to do it all. Our next project for the playhouse is a 55 gallon septic system. It is a guest house now and not used much so this is the perfect, easy septic system for it.
My fiance can do everything, electrical, plumbing, sheet rock, roofing, you name it and he can do it. He moved our "big" white house (600 sq ft) on his own with just a few friends to help. He was the mastermind of the job. He lifted it, moved it and had water and electricity hooked back up in it within 2 days. It would have cost us about $10,000 to hire a company to do it.
We never have to hire anyone to fix anything because Al can fix it or can barter with a friend if he needs help with a job. So, to answer your question more simply, Al and I can fix everything on our house or have friends who can help if needed and we never have to hire a professional to do anything. So we save a lot of money that way.
