Bungalow made of aerated concrete - experiences? DIY beginner questions!

I want to do as much as possible myself, I am not necessarily untalented and currently there would be enough time.

I can well imagine walls made of aerated concrete, especially because I could manage that quite well myself.

What costs can be estimated for heating (underfloor heating), water, and electricity materials? Just as a rough orientation…

To me, it reads a bit like (relatively) little money is available and therefore own work is planned. I consider that somewhat risky for the trades you mentioned (heating, water, electricity) if you don’t exactly describe yourself as handy and say: "My father has a construction company", but only call yourself not untalented. Building walls with aerated concrete works even if you are untalented. However, without a site manager or supervision, a house construction should not be attempted. I would suggest checking out Ytong house building (or similar companies). Building a house is not that easy. Technical trades must be done by master craftspeople, etc.

And yes, the time… why do you have enough time to do something yourself that others working in teams take half a year to complete?

So the desired living space would be a bungalow with 2-3 bedrooms, one bathroom, and a large living area. Ceiling height about 3.5m with a slightly sloped roof, 10° greened. If I find a simple software I can gladly draw it.

The roof structure made of glued laminated timber would span about 7m freely, so substantial beams are definitely needed.

That all makes the house considerably more expensive than a standard house.

No one here will quickly calculate for you whether you could make it statically. Sooner or later you will need a structural engineer to fill out a form for the building application.

I suspect that an architect is not necessarily planned here. More likely everything is done independently.

No, currently I’m just looking at what we like and how it can be implemented. When it comes to details, an architect and a structural engineer will be involved.

36.5 cm Ytong. 0.9 windows. Sufficient for KFW 55.

Thanks

I find that somewhat bold for the trades you mentioned (heating, water, electricity), unless you consider yourself skillful with your hands and say: "My dad has a construction company", rather than only not untalented.
Masonry with aerated concrete works even as an untalented person. However, a house build shouldn’t be managed without a construction manager or supervision. I would recommend checking out Ytong house construction (or similar companies).

Yes, and the time... why do you have enough time to do something yourself for which others take a whole half year in a crew?

Relatively little is just relative. I just want to keep it as inexpensive as possible, wouldn’t know what’s wrong with that... Lower costs = paid off sooner

There are plenty of certified tradesmen available and many of them allow you to assist or do part of the work yourself. My question was more about material costs and experience values like how much cable one usually ends up installing...

Well, why do I have time... that’s my business

No one here will quickly calculate for you whether it could statically work out. Sooner or later you need a structural engineer who fills out a form for the building permit.

Of course I need that, I was just looking for a rough estimate of what is needed. Or put differently, can I get by with around 10,000 for the beams or is it rather 25,000? From skimming the hall construction area there should be tables with reference values....

So, it’s not impossible. Three houses down they are also building as a family, father, son, wife, a thousand buddies, friends, only they are all professional craftsmen, the old carpenter, the son mason, etc. etc. Those are different conditions, they are also fairly quick, the efficiency is high.

Clearly, it will take longer than if I have it done. I don't want to do everything myself either, but as much as possible or as necessary.

You are not the first to consider building a house as a short walk compared to a marathon. But if only you are allowed to ask questions and expect sincere answers, then I hereby cancel the subscription to the questions. Good luck then.
