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.

Congratulations on your beautiful and unique home. It reflects your ideas and wishes, giving it a special character. This makes it a valuable addition – thank you for sharing it. I wish you long-lasting satisfaction and a daily enriching feeling of happiness and gratitude. Ultimately, building a house, regardless of price, size, functionality, design, or location, is a project aimed at creating a fitting shelter for your life. It seems that you have succeeded.

The roofs are currently being prepared for greening.
As mentioned earlier, the garage roof will have a different substrate since a lawn will be installed there.

Roof construction site with metal mesh, hoses; green fields and houses in the background

The other roofs will receive a standard green roofing system.
The first delivery of substrate is scheduled for today.

Please post pictures only when it’s raining or the weather is really bad. That way, I can better handle your view.

I really like how you’re doing it!

Hi Rick,
first of all, congratulations on your really well-thought-out overall concept (it's clear from your answers and descriptions that you put a lot of thought into it).
One question: How did you solve the issue with smoke detectors in your house? I've already completed that part in my own project, but when I was researching, I couldn’t find any good smoke detectors with direct 230V or 12V power and KNX integration.

The smoke detectors are from Jung with a wood design. They are wirelessly interconnected. Connection to KNX is via a gateway. The batteries last 10 years. If they fail earlier, free replacement is provided. After 10 years, the detectors should be replaced anyway...
I had the same issue as you (direct 230 V power + battery + KNX) and also wanted it to look good. That’s why I chose this solution.

@OWLer this afternoon rain is expected

Thank you for the information. We are now facing the same issue in our holiday home and I was wondering if there might be some nice solutions available nowadays. I also like the wood design. I need to see it in person sometime.
