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.

That's completely legitimate.

What product do you use for the impregnation? After extensive research, I’ve decided to use Keim products for our stairs. We clean with the concrete quick cleaner (although they were wrapped in wood during the construction period, it did get wet several times), then apply the Silangrund primer, and finally just the Fixativ from the Concretal glaze. We skip the glaze itself because we don’t want to change the color. I hope it will result in a finish that is as matte and invisible as possible...

That sounds more like sealing?!
I will just lightly polish the steps (which are currently wrapped) to remove the dirt and then apply a protective impregnation.
I am not yet sure which product I will use for the walls and stairs. For the garage, I will use water glass (sealing).
I will test different impregnations in the utility rooms and then use the best one for the living areas as well.

Sealing a garage with water glass
Tell me more, I’m not familiar with that yet.

Our exposed concrete staircase was delivered as a precast element and remained covered for a long time. It withstood the construction phase well, but I would like to clean it again. My wife thinks it looks fine as it is. We’ll see.
The staircase was impregnated at the factory. It works quite well.

@11ant Water glass is a proven solution for sealing or preventing sand erosion. It is also used for basement and wall waterproofing, as well as for fire protection. Affordable, simple, and effective. There is no mechanical stress on the walls anyway. Potassium water glass is the optimal choice in terms of price and performance.
