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

Modern villa with flat roofs, terraces, glass surfaces, green surroundings – several views.

Ridiculous nonsense. From above, it doesn’t look like a single-family house project, but more like a commercial development. With that amount of money (estimated), office buildings for 60 employees or more can be built.

Wait until it’s finished, when the supports are removed and the glass is installed. Then it will look like a residential building.

Yes, that’s true, but because our house is situated on a slope, it doesn’t appear so huge from above… We’re also wondering if we can still make the house watertight, as the windows are planned for the end of the month. Here, they can’t even pour retaining walls anymore because the white cement can’t withstand the cold.

How large is your plot?
For us, the glass will be installed later. Only the frames are being put in place. Due to the heat of the poured asphalt, the glass cannot be installed yet. So, it's a somewhat unusual process.

The plot is 1200m2 (12917 sq ft); the house will have about 330m2 (3552 sq ft) of living space. As far as I know, windows here are fully installed; we have liquid cork flooring in the basement, XL travertine tiles, and Naturofloor in the bathrooms.

How long does it take for the poured asphalt to dry? Do outside temperatures also play a role? Sorry, I have no experience with building at all ops:

Ok, your house is a bit smaller than I expected. Our plot is just under 2,500 m2 (26,900 sq ft).
The poured asphalt can bear load after one day. It will only be polished towards the end of the construction.
This way, we avoid having a screed that introduces moisture into the building and requires weeks of heating to dry out.
