I wanted to briefly introduce myself and share my project (which is, in reality, still just a rough idea) for discussion. At the same time, I hope to receive some guidance.
Well then. I am single and in my early to mid-forties, from the Hildesheim/Hanover region. For various reasons, I have decided to consider purchasing property for myself. Owning a flat is absolutely out of the question for me. If I am going to spend a significant amount of money, I want to be the master of my own home afterward. I am also not interested in buying an older property. These are either in need of extensive renovations or far too large for a single person. What remains is new construction. After some back and forth, it became clear that building in the traditional way common here doesn’t make much sense for me. I don’t have heirs to pass the property on to, and affordable plots are located so far outside the city that after 30 years of use they hold little to no value and are not suitable as an investment (real estate is only a good investment if there is a market at the time you want to sell it, and you never know that 30 years in advance...). So, building “American style” is the only option for me. That means building for one generation. It must be simple, fast, and affordable.
As the most cost-effective option, I have discovered wooden log houses on a slab foundation. For one person, a modest holiday home is more than sufficient. According to my research, most manufacturers offer models that are both eligible for building permits/planning permission and compliant with energy regulations (this raises the price somewhat but is doable). Additionally, the share of self-work can be very high since these homes typically come as kit packages. Excluding the slab and gas/water installations, the amount of self-construction could reach around 80%, assuming some craftsmanship skills.
The house is planned to be single-story so that I can continue living there as long as possible in old age (I currently have my parents as a sad example in mind). The intended footprint is about 9 x 9 meters (30 x 30 feet). This includes a terrace and an attached shed. I would cover energy supply with a combination of gas and a wood stove. While this isn’t the most energy-efficient solution, well-made wooden cabins have quite good insulation. I would avoid complex technology inside the house. A suitable wall-mounted gas boiler would suffice for hot water and heating, with the tank placed in front of or next to the house. The smallest tank size is also reasonably priced. Whether the tank is installed above ground or partially buried depends on the permit requirements. The easiest option is simply to set it up above ground, requiring only footings for support.
This whole project is feasible for me from a DIY perspective. I am not bound by time. If worst comes to worst, I can live on the construction site for a couple of months—I have an RV...
A challenge I currently see is the roof rafters. Due to their weight, they would be difficult or impossible to handle alone without outside help. I have some experience with renovation projects (conversions, major refurbishments) and at least have an idea of what to expect, even though I have never really built anything new. When doing the work yourself, it’s important to recognize your limits and get help when needed to avoid damage. The costs for this help are, according to rough estimates, a joke compared to those of a conventional house. The goal of “as cheap as possible” is not because of financial constraints, but rather due to the limited intended lifespan of the house. So much for the idea.
What really worries me more is the administrative side. What about structural engineering and liability? Do I need an architect, or would it be advisable to involve one? What about building permits/planning permission? Who takes care of them, and how does the process work?
I also have some small doubts about the plot of land. I need something between 400 and 500 square meters (4300 to 5400 square feet). The zoning plan must allow this kind of build, and I would prefer not to be required to start construction by a specific deadline, as is often the case. At least a quick look at real estate listings shows that such “small” plots outside the city are not offered. The minimum size available usually starts at 1000 square meters (11,000 square feet). I do have a few other things in mind, but if I don’t stop here, it will get too long for anyone to read.

If you want or have to spend very little money, at least you usually don’t struggle much with a growing selection based on your budget – which can simplify things, as I’m realizing from discussions with my wife now...
My thoughts on your planning: Take a look at a small photovoltaic system combined with the Panasonic 5kW (kilowatt) air source heat pump (often called "Geisha," available for under 4000€). With a suitably low heating demand, heating and hot water can probably be handled more cheaply this way – and if needed, the unit can even be used for cooling.
I don’t know much about structural engineering, but I assume that for prefab houses there is some kind of standardized structural design.
