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

This is outside the house. Above it is a terrace.
Our ventilated facade (aluminum composite panel) is wrapped around the corners and also used as ceiling cladding for terraces/balconies.
The "yellow nubs" surround the spacers of the battens.
These are thermally separated from the house. Since the ceiling is additionally insulated, these areas had to be cut out.

To maintain as continuous insulation as possible, the holes were carefully filled and glued with cut-to-fit insulation. The yellow material is excess foam.

Could you list your contractors? I think I would hire each and every one of them immediately.

Isn't that usually how it's done?

How do you find good craftsmen? It’s like hitting the jackpot in the lottery...

That’s exactly what I mean... tradespeople like those in this project naturally charge a premium. But even when paying more, you often only find those who charge premium rates but deliver little premium quality. Either you have known these guys for a long time or you’ve spent a lot of time and/or been lucky in your search.
