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

Nice cabin! I would like it too, but since we have three children, it might be a bit tight there.
Like many others, I don’t like the bathroom being accessible from the kitchen. I would place it on the exterior wall instead, at the end of the storage room, and reduce the storage room by about one meter (3 feet).
The pool looks good, but personally, I would prefer to use it not only in summer. It would be nice if part of it were integrated into the house. One suggestion: for me, only a saltwater pool is an option. The water feels much more pleasant.

I know a good planner and integrator for KNX.
He also equipped the house at my parents’ place, and I have looked at some of his other projects.
I’m sure there are other good ones as well. The problem is often something else.
KNX is never just a matter of saying “I would like KNX.” You have to be very involved yourself, know what you want, and have some understanding of the topic (infrastructure, addressing, ETS programming, etc.). Or you have to do it completely by yourself.
We are going with Gira even though it is not quite as flexible. Actuators will also come from different manufacturers. My wife is not very tech-savvy and knows the Gira visualization. Besides that, I don’t want another app. At my parents’ place, I hardly use the panels—usually just a phone or tablet.
The ventilation is designed differently for each room and is also adjustable. So I have no concerns about it being too loud, for example, in the bedroom.
There is a garden planner, but this is still somewhat on the back burner.
I had to plan the main irrigation system because we have to supply the corresponding areas from the cistern (through the filter).
The green roofs will have varying thicknesses of substrate. This means that larger plants will be possible on the garage roof as well.
There are already a few ideas. It will be relatively low maintenance, but it is important to us that we create and preserve enough habitat for insects, birds, and so on.
The toilet on the ground floor is not ideally positioned. I completely agree with you there.
But the rest is perfect for us. Moving the toilet would worsen many other things, which we do not want.
Originally, we considered a natural swimming pond or pool. The regeneration zone would have been near the pavilion (which technically would not have been necessary, just for appearance), and the swimming area towards the house. However, a natural swimming pond should not be heated (above 22°C (72°F)), and some people also have a problem swimming in it because it doesn’t look sterile…
So we switched to a saltwater pool with a full-length liner.
After looking at several pools, it became clear that we wanted a stainless steel pool. This is not compatible with saltwater. There are some manufacturers offering this (made of V4A stainless steel), but the costs are enormous and durability is still not really proven.
Our pool can be heated, is insulated, and covered. So you could jump in even at lower outside temperatures (if it’s heated or not frozen over). We did not want a pool inside the house or extending into the house. Those areas should be separated. You need dehumidification (which uses a lot of energy), etc.
