Haha, my neighbors' garden is crooked and wonky.
.....in your eyes, maybe he likes it just like that and grins at perfectly straight layouts....who knows....
There may be worse things, but coming into my house for years via an improvised wobbly wooden staircase?
Well, there is also something between the extremes that one can live well with. A house and its surroundings can grow gradually, and you can always be happy about a new step. You sit on the terrace and ponder how to design this or that corner; with your own possibilities and away from the DIY store brochure. I think you can allow yourself that time. The basic things can still be arranged from the start, like stairs, access, etc.
Not being able to use the entire garden for years because it is steep and wild overgrown?
You would have to explain the term "use." You can use it from day one by starting to shape it slowly and gradually yourself. Somehow it has become established over the last years that the house must be spotless immediately. When we built at the time, the house was not plastered for 2 years, the garden came much later and only as far as you could mostly do it yourself.
I might as well move into an apartment.
That depends on why you are building a house. I am also building it because I want to gradually beautify things, for myself! A house is an endless construction site anyway but also in a positive sense, you engage with it, save for something, are happy after completion, etc., drink coffee and develop new ideas along the way.....and so on, that can bring joy.
When you read it like this, you always realize what is already considered a lower standard here in detail. My dear man, it makes your ears flap and no wonder that there are always such big numbers before this -k-. If someone spends 100 or 200 thousand on their outdoor area, that’s great, then they probably have it left and it is worth it to them; but then they should never complain. But partly it is portrayed as if it could hardly be otherwise. I also mostly read that things are contracted out rather than tackling them yourself. That is probably an outdated way of looking at things but I (and also my wife) have learned to do concrete work, lay tiles, etc., and yes, that was our main occupation for a long time (years). Among predominantly young people here in the forum, I miss this attitude somewhat or rather read too often complaining about prices instead of critically questioning what high demands one actually makes.
I can absolutely understand if someone does not feel like doing it and still wants it to look nice. Then they have it done and pay for it. But then they also know this beforehand and really plan this position for the outdoor area properly into the financing; they should only be surprised if they want it fancy but neither like paying nor hard own work.
