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

Run your finger over the display glass of your phone and then over the exposed concrete.
That’s the difference. The ground and polished walls feel like smooth and clean glass.

The question is which appearance and texture you want to achieve. What I find so nice about concrete is its versatility. It can be as smooth as glass or have a textured surface like formwork patterns, and can be either rough and raw or glossy and refined.

I’m sure you already have the desired result clearly in mind.

Best regards! mini_g!

Concrete is extremely versatile. I have the desired result in mind, but we’ll have to see if it turns out that way in reality.
Merry Christmas.

We are very satisfied with our concrete surfaces (ceilings and some walls)! A small tip: Make sure that, for example, the plasterer and/or painter uses proper masking tape on the concrete surfaces (if necessary). We now have some tape residue on the concrete. We hope that since the tape was grease-free, the residue is only moisture and will no longer be visible soon, but you can point this out in advance!
Otherwise, as always: an awesome place! Wishing you continued success!

Today, I quickly primed 300m2 (ceilings and walls where no insulation will be applied) in the garage with a white primer. The topcoat will go on tomorrow. If time and motivation allow, I might also prime one of the utility rooms and the storage room. Currently, there are hardly any installations in place, so there is not much masking to do...

The plan worked
The garage received its topcoat today, and the technical room and storage area have been primed.
Since the question about the paint comes up from time to time:
- Primer: StoPrim Color white
- Topcoat: Sto Silco G AW15

Applied with a Wagner PowerPainter 90. The primer was diluted about 2%, the facade paint about 5%.

Here is a (partial) picture with still wet paint:
