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.

Wow. The style is very much like mine... This looks like a really exciting project. I have a question about the planned pool: What (construction) costs are you expecting there (all-in)? My wife is also dreaming of something like that – and I think it would exceed our budget (I understand that a stainless steel pool is a somewhat luxurious option). Just so I have a rough idea.

Wow! You don’t see a palace like this every day. Best of luck with the construction phase.

Considering the amount of glass and the budget required for this project, I am surprised that no air conditioning is planned. Cooling coils are just a gimmick.

If the budget allowed, I would leave out the supports. Especially round ones made of reinforced concrete—they don’t really suit the house and are more typical of commercial buildings from the 1990s.

Hello Alex, we thought about this extensively.
In the end, we decided against using fan coils or similar systems.
There is an additional split unit that precools the intake air. The air is also directed about 40 meters (130 feet) along the floor beforehand.
Cooling with air is always a less effective option and only really viable at an air exchange rate of 4 or higher. But we don’t want indoor temperatures at 18°C (64°F) when it’s 30°C (86°F) outside. Our goal is more to buffer temperature peaks.
Due to the solid construction, shading, and partial overhangs of the glass surfaces, this should work out.

There is also an elevator in case anyone was wondering if it’s inconvenient to always walk up a floor to reach the living area. Doors and everything else are designed to be wheelchair accessible, so hopefully we can live here comfortably well into old age.
