Hello everyone,

we are dealing with the topic of building/buying a house from time to time and slowly we want to move forward and plan a bit more concretely. However, I am overwhelmed with all the information you find or don’t find on the internet and would therefore like to discuss my idea here with you.

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

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 sloping roof, 10° greened. If I find a simple software, I can gladly draw it sometime.
I can well imagine walls made of aerated concrete, especially because I would manage that quite well myself. The roof construction made of glued laminated timber would span about 7m, so solid beams are needed. The advantage is that no load-bearing walls have to be built. The living area would be completely without partition walls. That would have to be calculated by a structural engineer, or can someone here roughly estimate that?

I have a few questions directly about aerated concrete. It is diffusion-open as far as I know. So, if it is clad with wood on the outside and plastered with clay on the inside, that should create a pleasant indoor climate, right?
Can I achieve a KFW55 house with appropriate windows? What thickness would you then have to calculate?
Electricity and water will then be laid in the wall, is there anything to consider because the stone is thinner there regarding statics and thermal insulation?

What can one estimate as costs for heating (underfloor heating), water, and electricity materials? Just a rough orientation.....

Thanks to you all
Bastian

These are actually almost all questions that your architect has to answer for you anyway... Worrying about them beforehand seems unnecessary to me.

I assume that an architect is not necessarily planned here. Rather everything is done independently.

Without an architect, no building permit...

Yes. Keyword building submission authorization. It could also be done by the civil engineer as a structural engineer.
