If you are in the States then unless you're licensed in like 30 areas, you will not be able to build your house "autonomously". You will need permits for everything - properly doing concrete for walls and ceilings is a huge undertaking. You will need to hire electricians and then get your local city to inspect everything. Again, if you plan on laying anything within your concrete structure, you will have a ton of back and forth in terms of approvals and inspections. Before I forget, you will also need to make sure you run your plans by a professional since you may not realize something you need to run within your flooring or foundation. For example, I have worked on a basement-less home where the ground floor is concrete slab. Well, all sewer, electrical, water, etc was run through this in 1977. We wanted to make certain extensions but were limited by where certain water, gas and power outlets were already run. For one section we had no choice so we trenched the foundation to run new water and sewer lines. It was not easy. It was not cheap. It was a lot of work. So, if you do this, you can't just assume you have planned everything correctly in your head. You have to hire someone to at the very least look over everything and assure you that you're not forgetting anything. Otherwise it will be twice as expensive to go back and fix things later. The biggest thing you need to do focus on right now is your budget. If you told me how many square feet you wanted your house to be, we could estimate something for the base concrete costs - including permits and labor. But your house will need windows, flooring, carpet, wood, doors, HVAC, tiles, tiling, fixtures, lighting, electrical, moulding, etc etc etc... you can easily blow your budget on just your foundation, or in just one bathroom where you pick the wrong tiles or go overboard with too many fancy design and aesthetic choices. A custom shower with a modern shower system and a concrete floor that allows for custom tiles in the shower for example will be costly in terms of time and effort, but something you can do yourself. You will again need to make sure any plumbing in this bathroom is properly done otherwise your local inspector will literally make you tear it all up and do it again properly. tldr - there are a million ways this can wreck you. Unless you live on a farm in the middle of nowhere and are a millionaire with access to contractors who can deliver all these things to your land for you to experiment and play with... I would not consider building a massive concrete house "autonomously".
