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

@Climbee There isn’t much new to see on the exterior.
Today, the colored topcoat was applied in the office and guest room.
The roofers are still working hard and will probably finish the top roof this week.
The HVAC team is busy welding and installing the pipes for the heating system.
Outside, work is ongoing on the foundations for the enclosure.
Today, the cable connection finally arrived, including the outlet and amplifier. The main connection has been there for a while. But how they can send guys out with such a toy drill and bit... Do they only serve customers with wooden houses???
We ended up borrowing the large Hilti drill from the HVAC team. But even the good Hilti SDS drill bit wore out quickly. In total, it managed to drill three holes (two bits broken plus the toy one). But it holds fine as is...
Anyway, I now have internet and immediately installed additional cameras for the construction phase.
The city also finally relocated a streetlight.
Maybe I’ll have time to upload some pictures tonight.

I need to ask about that. How did it work for you? And what did it cost? We still need to sort this out with the city.

I believe we paid around 3,500 (currency). Extension, construction including relocation, pick-up and delivery.
Transport won’t apply to you. There could be additional costs for electrical work. That was handled at the same time in our case because the utility company had to move their box. The sidewalk was already open anyway.

It was informal for us. Small village and neighbors.

Discussions, applications, etc. were not really problematic overall. We have completed the civil engineering work. I don’t have the invoice yet, but it will probably cost between 3,500 and 4,000 plus our own labor.

With my estimated 4k according to the budget planning, I’m probably about right. Thank you all!

As promised, here are some recent photos.
Roof work on the topmost roof. Paint, elephant skin coating, insulation, sealing, sloped panels, and double sealing are already in place underneath.

Construction workers working on a roof surface; insulation, materials, and gas cylinders are ready.


A few heating pipes. No plastic.

Black pipes running parallel under the ceiling, with brackets and green markings.


Nicely insulated internal drainage.

Black pipe on the ceiling with a bend, secured with clips; cable bundle next to it.


Office. Still damp and actually a bit brighter in real life.

Unfinished interior with yellow walls, raw concrete floor, and door to the construction site with barrier tape.


Hard walls and reinforcement have stressed the material.

Two spiral drill bits lying on dusty concrete floor next to a white pipe.


A few more heating pipes.

Black metal pipes on a concrete ceiling at a construction site, with blue and red hoses hanging down.


Guest room. Also still damp and somewhat brighter in reality. A small bathroom will be installed here as well. It will be built with drywall. That will also need to be painted.

Unfinished room with green drywall, ladder on the left, yellow buckets and extension cord.
