Build a wooden house yourself

Hello, I would like to build a very cheap wooden house myself without much fuss, can someone give me some information who has experience with it? It should be about 70 sqm. For now, it's only about building cost-effectively, so just setting up the basic framework. What kind of wood should I use, where can I get it best, and how would your own planning look like? I imagine something like in my picture.

Residential house, holiday home or garden shed?

I wanted to live inside because I got a plot of land, so a kind of vacation home would be great, about 70sqm. Basically, I'm only interested in building with wood and how to do it best. Insulation and interior finishing are then no problem.

So you have a structural engineer on hand to ensure compliance with the same and for the energy saving ordinance?

And you yourself have enough time to build yourself? So for the next 3-4 years.

I have a structural engineer on hand, but how on earth is it supposed to take 3-4 years? My father built his wooden house in 2-3 months; it’s not supposed to be anything massive or big, just something smaller.

Why don't you ask your father then, if you already have experience in the family?

For many here, your plan probably does not seem feasible, which is why it is pointless to engage with it.
