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

I would leave out the supports if the budget allows. Also, round reinforced concrete supports don’t really fit the house and are more typical of commercial buildings from the 1990s.Hello Lump,
the supports won’t be as bulky as shown in the rendering. Whether they will be made of concrete or steel is still under discussion. Achieving a clear span of over 26 meters (85 feet) without supports is very difficult. Maintaining a deflection of less than 0.5 cm (0.2 inches), which is necessary because of the windows, would be impossible without them...
Especially since we require higher floor loads on the upper level.
We have looked at several houses and like this one. However, we understand that it won’t appeal to everyone, which is perfectly legitimate.
Also, the balcony and terrace railing shown in the rendering will not be installed as depicted, but will instead be a glass system.

Wow. The style is mine..... Well, not really mine, but it will definitely be great to live in. Maybe a bit spacious.

Due to the solid construction, shading, and partial coverage of the glass areas, it should work out.Because of the heavy coverage of the glass surfaces, the areas will remain quite dark and cave-like—despite all the glass. But of course, you can’t have everything: protected seating areas from rain, sun protection for the house, and natural light inside...
My spontaneous thought was: why not add a (small) green roof terrace at the very top? At least a lookout or something similar would be nice. Of course, that also depends on the view.

Wow. This style is just my taste..... This looks like a very exciting project. I have a question about the planned pool: What all-in (construction) costs are you expecting? My wife also dreams of something like this – and I think it would exceed our budget (I know that a stainless steel pool is the more luxurious option). Just so I have a rough idea.Hello montessalet,
understandably, I won’t be sharing exact costs.
Now, about the dimensions.
Our pool is 20 meters (65.6 feet) long and 3.42 meters (11.2 feet) wide (wider than shown in the illustration). It has an increased water depth and will be an infinity overflow pool along the full 20 meters (65.6 feet).
As you correctly said, stainless steel is the luxury option.
The cover alone for this length is expensive, and with polycarbonate you could almost double that price.
If sealed with a liner, including all pool technology, a cover made only of PVC, no overflow pool, and WITHOUT all the concrete work, the cost would already be close to six figures.
Ours will cost more than twice that.
Depending on how much you can do yourself, it can be cheaper. Also, our pool size is definitely not average.
A “normal” sized pool with good equipment can be done well under 50k.
Steel wall pools and such can be even cheaper, but they are not comparable.
Another point is how and whether you plan to heat the pool...
Is your drainage system sufficient to handle the backwashed water? (usually about 1 cubic meter in 2-3 minutes)
If you have further questions, just ask.
Best regards

My immediate thought was: why not add a (small) roof terrace on top of the green roof? At least a small lookout or something similar would be nice. Although that of course depends on the view.Hello Otus11,
there are plenty of unobstructed window areas. We have looked at sun position simulations over the entire year.
The upper floor roof will not be greened but instead will have a photovoltaic system installed (just under 10 kWp).
It wouldn’t be practical as a terrace either due to long access routes and such. The view is good,
but we already have that from the entire upper floor. Because of the hillside location, the view is not an issue.
We also already have more than enough terrace space. The ground-floor terraces will be used the most.
The small terrace on the upper floor is only intended as an exit from the dressing room.

Understandably, I won’t disclose the exact costs.Why not? How much more anonymity do you need? I estimate around 2.5 million. More expensive properties have been planned here as well.
