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

So, we have no concerns regarding building biology here. That is indeed the most important thing.
As planned, work began today on the second and final layer of poured asphalt.
In the photo, you can also see the excess filler material. The asphalt was still at 100°C (212°F) at that point.
In the bottom right, you can see that there is sometimes some debris lying around on our construction site as well.
I am still standing on the first layer from yesterday.
Of course, we also experience occasional delays and coordination issues.
Since yesterday, the situation has been quite dynamic.
The Swiss window manufacturer contacted us, saying there is a chance they will be able to cross the border next week and install the glass.
The problem is that the floor needs to be sanded beforehand. There are some tight spots that can only be properly worked on from outside. However, the company is based in Austria and currently cannot provide firm scheduling commitments.
Therefore, today involved an on-site meeting plus video conferences...
Outcome:
- The tolerance of the doors is sufficient to clear the unsanded floor
- This morning, the German specialist company responsible for transporting the glass was on site (discussing which equipment will be needed, such as a crane with mounting boom, suction lifters, handheld tools...)
- The scaffolding mostly needs to be taken down
- Passes for the Swiss team have been issued
and so on.
Currently, the plan is to carry out a partial installation. That means all glass on the upper and lower floors, but only three panes on the ground floor. This is supposed to start on Monday next week.
I am still a bit skeptical about this.
As soon as the poured asphalt is finished tomorrow, work can begin on filling the drywall joints and painting. I will handle much of this myself again.
I can also start working on the PU joint seals.
The painting needs to be completed before the installation of the acoustic ceiling begins.
We will need to protect the ceiling while the floor is being sanded.
There was also a phone conference with the building authority today regarding one of the wall sections. We are sure to find a solution together here as well.
Things remain interesting.

As planned, the second and final layer of mastic asphalt was applied today.Is this inside the house, or why use mastic asphalt indoors? I only know asphalt for paths or roads.

In a hot state, for example during processing, hazardous emissions from the bitumen content must still be expected. Protective measures according to technical regulations should therefore be strictly followed.Where exactly were the protective measures visible again in the photos?
@annab377 I guess you haven’t read much of this thread yet. In our construction project, some things are done differently, more specifically, or less commonly. Have a look at a few pages earlier where I listed some reasons (seamless, warm underfoot, flexible, waterproof—for example, also in the shower, etc.). Or try searching for Bituterrazzo. In general, it requires more effort because everything has to be designed to withstand the high temperatures during application. The advantages outweigh the effort for us. Our style is Bauhaus.
