Building as a Single Person - Exchange of Experiences

I do think you have to be financially equipped for several (own) houses in life accordingly ... (my post #22 also refers to post #13 by @ )

Not if it happens one after the other and according to your own needs and possibilities. I may not count myself among the financial elite here but have nonetheless lived in various own properties. Often, not always, it is a question of personal attitude, flexibility but especially of the chosen life path. It is not a question of better or worse, but I have often heard that one cannot make the necessary change because.....x-y-z.... people don't want to pay the "price" so gladly. If these placeholders had played a bigger role for me, I would still be living in a simple, parental suburban house today, and it wouldn't necessarily be bad there either. Fundamental changes in life that have to be decided are difficult; many people just don't want to dare that; then it is often a popular excuse that you can't do it yourself for reasons x-y-z...... but you can! Who forbids me to live differently or elsewhere if I don't like it here or so? No one! This is no problem if one is satisfied with one's own "old" and does not become jealous of those who have consistently changed such things. Money is usually only the excuse, the "money" is usually with those who have changed less anyway; change also costs a lot of money or brings in less afterwards.

It worked that way for me too. Acted according to needs and possibilities. At 21 I bought a 3-room condominium with 65 sqm. Sold 5 years later. At 26 I bought a terraced house in the middle. Sold 7 years later. At 33 we bought a semi-detached house. We have been living here for 5 years, the house will be sold during the year. At 38 I am/we (m,44) building a detached house. Hoping to stay healthy and to live longer and then spend old age in a nice apartment with a roof terrace :) For the OP, due to the situation with the children, I would maybe buy the land now if I liked it very much. Wait a few years until it becomes clear what educational/professional paths the kids take. At the moment there is still the possibility that they might really want to move to the father. And in the meantime plan the new house, with max. one "spare room". :D and exactly the way you want it for yourself.

Hoping to stay healthy and also to grow older and then spend the retirement in a nice apartment with a rooftop terrace

That sounds interesting!
We had decided on this fancy rooftop terrace version until the current project fell through due to the unreliability of the owner, even though we already live there :mad: and now we are just building a little house for the two of us again.
At first we were sad and also unsettled, then we tackled it and now we are glad how things turned out. The resulting financial and other pains we had/have to pay for it.
I think this is the last owner-occupied home.......but who knows..... :cool:

I live alone in a 140m2 house. It is a bit too big but not so much that I couldn’t usefully fill it. I have three bedrooms, two of which are planned as children's rooms and one master bedroom. I don’t necessarily need the space (there was no other option from the developer) but it is absolutely fine and doesn’t really add much to the follow-up costs.

I believe three rooms are better for the resale value.

Personally, I wouldn’t want to build alone. I bought a finished (well, what the developer calls finished) house and the subsequent planning of the connection work almost pushed me into a construction burnout. It was hell; tradesmen who didn’t show up. Tradesmen who came but only botched things, tradesmen who showed up easily two hours late and considered that normal.
The time needed for planning and decisions is a thousand times more than for an entire house. Personally, I would never do it again. Besides, I almost always find existing buildings more charming than new builds. I haven’t seen a new build yet that really blew me away. You can often see that the love for the (architectural and construction) craft is missing.

lol … if you get upset about 2 hours, the burnout is on you :cool:

An example that you can stay calm even with problems and still succeed: Today the screed arrived at our place. Only in the ground floor, the plumbers had done the floor construction wrong. 20cm insulation instead of 17.5. now the screed didn’t fit on it. I casually chatted with the boss at 7:00 am, in the afternoon someone was already there to dismantle the underfloor heating. Wednesday it will be finished and on Monday the rest of the screed comes. And… do I get upset? no. Doesn’t help. Looking for a constructive solution is the motto

With the second or third house, everything goes very smoothly. You know the customs on the construction site and become more relaxed (and pay more attention to the really important things in the house) ;)
