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.

@haydee We have an active cooling system and a high air exchange rate. This means the ventilation can operate even when the outdoor temperature is warmer. The air cools passively as it is drawn through the ground and is then further cooled actively. We live quite far south in the Black Forest at over 700 meters (2300 feet) elevation. I believe the solar gain is similar.

We can exchange the air inside the house in less than an hour. We can also ventilate simply by opening windows; on the ground floor alone, we have two opposing glass elements, each 5 meters (16 feet) long. That’s 10 meters (33 feet) of continuous opening. Due to their weight, they can only be operated by motor now. And of course, there are additional standard-sized opening options as well.

Yes, I was also wondering where they could have fit it in given the tight space.

No sauna?
The sauna is planned to be inside the fitness room.

That is fine then. I think it’s good if the fresh air intake can be cooled.

How high are your rooms?

The kitchen looks great visually, but from a practical cooking perspective, it feels inconvenient.

The rooms will have a finished ceiling height between 2.78 and 2.80 meters (9.12 and 9.18 feet).

For the kitchen, it would be more practical if the island were positioned perpendicular to the kitchen cabinets. However, the room layout and our preferences do not allow this.
The layout follows a workflow sequence.
So the refrigerator is on the far right, followed by washing, cutting, prepping, cooking, and so on.
The oven is also further to the right.
On the left side, there is only a wine cooler, which is mainly accessed from the living or dining area—just like the coffee machine.
It’s easy to misjudge the size here. We were surprised how large a 3.60-meter (11.8-foot) kitchen counter actually is.

Mine isn’t much smaller. Do you also get fully stocked?

A wine cooler isn’t really necessary for preparation.

That is why the wine cabinet is placed all the way to the left, as it is not part of the regular kitchen workflow.
With a lot of space available, there is always the risk of accumulating too much...
