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

The garage is definitely impressive.
The doors aren’t really my style. Am I right in seeing that there’s a gap at the top? If so, doesn’t that defeat the purpose of a soundproof door?

I’m guessing that’s the "aluminum shadow gap."

Overall, I think the doors are fantastic, even though I would have chosen a different type of wood. It’s just the floor I’m not really comfortable with.

They have a continuous aluminum shadow gap around the perimeter (outside the casing).
It is neither leaky nor drafty. Even the standard doors provide excellent sound insulation.
The floor drop-down seals enhance this effect even more. The fact that the walls are made of concrete greatly improves soundproofing.
It’s really unusual how quiet the house is when I’m here without any construction workers.
Walnut is a recurring element in our interior design. Because we have a lot of natural light, it works very well.
Others prefer white walls and doors. That is a matter of personal taste.

Did you install the ventilation room by room so that no air transfer through the doors is necessary? I can't remember offhand.
rick201825 Sep 2020 11:55
Yes, in most areas there are separate supply and exhaust air systems. In some cases, they are oversized by up to ten times due to our air conditioning requirements.
We have already started operating the heat pump. It is used solely for cooling and is supported by a cooling buffer, chilled water unit, dehumidification, and so on, which cools the air.
Theoretically, we could also cool the floor, but we do not want to.
Heating and/or pool cooling would also be possible.
The biggest advantage is that we can send the heat in an additional circuit to the pool. This only costs us electricity for circulation.
If we ever want to heat the pool properly, we use our gas heating system.

you can park the Aida in there!
I’m afraid that for a cruise ship-sized motorhome, you’ll still need a parking spot somewhere else.

Fortunately, the weather is nice today. 1,080 groundcover plants have been delivered. They look quite few in the trays.

We will need about 500 more plants to fill the bed. Unfortunately, none are currently available.
