Bauhaus concrete villa with core insulation - experiences

Hello everyone,

I just wanted to say a quick thank you and introduce myself.

For about 1 1/2 years I have been a silent reader to gain inspiration and above all more knowledge about construction technology.

Now about me:
After more than a year of searching for a plot of land, I was able to buy one from a developer because he could not realize his plans quickly.
Thus, we found our dream plot (good location, 2500 m2, slight slope, own underground spring which we have to preserve and are allowed to use).
There was still an old house on the plot which we have since demolished.
There is no development plan, so §34 applies. In a first verbal inquiry at the building authority, almost everything we planned was rejected.
So we submitted an official building preliminary request, involved the right people, and had lengthy discussions. In the end, we received a positive decision.
Thus, there was nothing standing in the way of the building application. The building permit should come in the next few weeks as there are no changes to the building preliminary request.

My wife (37) and I (36) want to build a Bauhaus villa in southern BW.
Built from concrete (with core insulation) or in combination with insulated precast parts.
A lot of glass (all-glass system), textile shading, KNX, fast network both wired and wireless, strong controlled residential ventilation with additional cooling coil, stainless steel pool, large cistern, etc.)
The electrical planning must be 100% right because you can hardly change it afterwards.
Since I am friends with an architect with a larger office, it was clear which path we would take. Such a house can actually only be realized with an architect.
I also personally know the electrician and KNX system integrator, as well as the owners and working methods of the executing heating, sanitary and ventilation company.
Some trades have already been awarded and part of the equipment is also already ordered.

I am already looking forward to when it really gets started and to the final result. The goal is to move in by the end of 2019.

So again many thanks for the information I have received from you so far.
If you have any questions, just get in touch.

Attached is the draft, although not the final version. There were still a few minor changes.

Greetings from the Swabian region

Oh. The style is mine..... That looks like a very exciting project. I have a question about the planned pool: What (construction) costs are you expecting there (all-in)? My wife also dreams of something like that – and I am of the opinion that it would exceed our budget (I am aware that a stainless steel pool is the somewhat luxurious option). Just so I have a "ballpark figure" too.

Wow! You don't see a palace like this every day. Good luck with the construction phase.

With the amount of glass and the required budget for this project, I am surprised that no air conditioning is planned here. Cooling coils are just child's play.

I would leave out the supports if the budget allows. Also round in reinforced concrete.. doesn’t fit the house at all and is more typical for 90s commercial buildings.

Hello Alex, we thought about that for a long time.
In the end, we decided against working with fan coils or similar.
There is also an additional split unit that pre-cools the sucked-in air. The air is also routed about 40 meters along the floor beforehand.
Cooling with air is always a worse choice and only really makes sense from an air exchange rate of 4 onward. But we also don’t want 18°C inside when it is 30°C outside. It’s more about buffering temperature peaks.
Due to the massive construction, shading, and partial overbuilding of the glass surfaces, it should work.

There is also an elevator in case anyone wondered if it is impractical to always climb one floor to reach the living level. Doors etc. are all planned to be wheelchair width so that hopefully we can live in it into old age.
