Hello everyone,

I just wanted to briefly introduce myself and say thank you.

For about a year and a half, I have been a silent reader here to gather inspiration and especially to gain more knowledge about construction technology.

Now a bit about me:
After more than a year of searching for a plot of land, I was able to purchase one from a developer who couldn’t move forward quickly with his plans.
So we found our dream plot (good location, 2500 m² (0.62 acres), slight slope, underground private spring that we have to preserve and are allowed to use).
There was an old house on the property, which we have since demolished.
There is no zoning plan, so §34 applies. During an initial informal inquiry at the building authority, almost everything we planned was rejected.
So we submitted an official preliminary building inquiry, involved the right people, and had lengthy discussions. In the end, we received a positive decision.
Therefore, there is nothing standing in the way of the building permit. The building permit should be granted within the next few weeks as there are no changes from the preliminary inquiry.

My wife (37) and I (36) want to build a Bauhaus-style villa in southern Baden-Württemberg.
It will be constructed from concrete (with core insulation) or in combination with insulated precast elements.
A lot of glass (full-glass system), textile shading, KNX, fast network both wired and wireless, strong mechanical ventilation with additional cooling coils, stainless steel pool, large cistern, and more.
The electrical planning must be 100% spot on since it’s almost impossible to make changes afterward.
Since I am friends with an architect from a larger firm, it was clear which route we would take. Such a house can basically only be realized with an architect.
I also personally know the electrician and KNX system integrator, as well as the owners and work approach of the heating, plumbing, and ventilation companies involved.
Some trades have already been contracted, and part of the equipment has already been ordered.

I’m really looking forward to getting started and to the final result. The goal is to move in by the end of 2019.

Once again, many thanks for the information I have received from you so far.
If you have any questions, just let me know.

Attached is the design, though not the final version. There have been a few minor changes.

Greetings from Swabia

Our nephews and niece will inherit, or my brother if we pass away before him. However, they will have to accept the house as it is. If the land and living situation remain the same as now, they probably won’t complain.

To me, that’s the difference between a house that Uncle H. and Aunt Hilda build for themselves and a house that still has a sensible structure for anyone even after 100 years. The word “in need of renovation” comes to mind immediately.

And no, I don’t find the “after me, the flood” attitude desirable at all, especially when it comes to building a house. A lot of resources are used. It would be appropriate and environmentally conscious if a house lasts for more than one generation.

How can you know what kind of structure everyone will need in 100 years? Maybe the heirs or buyers won’t have children either. The property will need renovation anyway. And every generation has different ideas about their living space.

This is not an "after me, the flood" attitude. Something of lasting value (house plus land) will be passed on. The house could be remodeled or extended. Whether the next generation tears it down and thereby wastes resources is not the fault of the builder.

With the way technology is advancing, there’s definitely a point there.
Still, I’m not building my house just for myself, but in a way that someone else could use it too. Especially once I go beyond 160m² (1,722 sq ft). In my generation, that usually means parents plus two children.

I do think there’s a significant element of selfishness involved. It’s not a big drama, but my basic approach is somewhat different.
A house that only suits 1% of families, in my opinion, has less social value than one where 80% can live very well.

In the end, though, it’s probably all nonsense anyway, since in 50 years we might need our own wind turbines, and all houses with pitched roofs could be too steep for that, or something like that.

“Wow, cool house!” my 14-year-old said yesterday. When I pointed out that no kids' bedroom was planned, he replied that the pool would be enough for HIM in the summer, and in winter he would make himself comfortable in the pool pavilion, because then he would FINALLY have some peace and quiet! Well, that works too.

Back to the topic, cool house! Can you recommend an HVAC designer?

I don’t see any drama here either. Your attitude is legitimate and understandable.
However, individuality should not be equated with selfishness.
You are focusing mainly on families, which probably represent the largest group. But there are also other buyer groups (singles, couples without children, older couples whose children have grown up...). They appreciate a house that is better tailored to their needs.
Personally, I would consider it a waste of resources to build rooms that I won’t need during my lifetime, both from an environmental and a financial perspective.

That’s one way to look at it.

That’s also an option, or just use the guest room.
Regarding HVAC/plumbing, I’ve had very good experiences with the Maurer Group from Schamberg. You’re heading towards Lake Constance/Bodensee, right?
