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

Ah yes, we won’t have a lawn, but the usual greenery instead.
If the mats are that expensive, I’ll take a look at other options. As I said, there is no budget for it at the moment, but eventually the garage roof is planned to be greened. We were told the EPDM membrane functions as a root barrier – it’s already installed.
21°C (70°F) is a nice swimming temperature; do you have a cover mat that can also protect the water from cooling down?

Green roofs usually consist of more than just a root barrier with substrate and seeds on top.
It’s better to wait a bit longer and save up, as it’s unfortunately not very cheap.
Gravel is commonly used as a non-vegetated layer, but other types of stones or tiles can also work.
For the pool, we have a polycarbonate cover with a solar function, although it has not been installed yet.
This cover floats on the water surface (which is necessary because it’s an infinity pool). If someone accidentally steps on it, they only get wet feet but won’t fall through.
The cover helps increase warming during the day and reduces cooling at night.
The pool is also insulated on the sides and bottom.

For us, it was done at the end of April – using a sedum mix.
They need some time to take root, and when cold autumn winds blow, half of it can get blown away. If it gets too cold before they establish, the plants can also freeze.
But be careful: unfortunately, it wasn’t actually a mix in our case. By "mix," I mean different varieties, but it was only one variety in the end. I then planted a few different sedum species myself in between to avoid it looking too monotonous.
The garage roof is about 60m² (645 sq ft). I would have to check the price again, but your figure seems rather expensive to me.
