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

Properly, with company cars, business meals, and all that stuff (?)

The tax auditor will probably have fun with that. But yes, some expenses for the home office are attributed to the asset, such as the tax software.

I used the holidays to finally work on the PU/hybrid joints on the garage ceiling.
They don’t serve any functional purpose; I just didn’t like the look of the open joints.
If you plan to do something similar, definitely get a battery-powered caulking gun. Firstly, your hand will otherwise get numb, and secondly, the cartridge volume is too small. So, use the 600ml (20 fl oz) sausages right away.

Since the ceiling has V-shaped joints, no backer rod is needed and couldn’t be secured anyway. So, I glued the joint sides and dusted them with a brush. The material I used adheres extremely well and only rarely requires primer treatment on the joint surface. That was one reason I chose this product. On my substrates, no primer was required anywhere.
Then fill nicely. It has to be enough so that the entire groove is filled when smoothing. The material sticks very strongly, even to the hands. Luckily, I had enough disposable gloves (bought before the crisis).

Especially when smoothing, it splashes nicely over the hands (if you use too much). The workability is not comparable to silicone. Even soapy water doesn’t help, as the material cures through moisture...
Finally, peel off the tape and enjoy the result.

Over the days, I applied 15 kg (33 lbs) of PU/hybrid sealant into the ceiling joints.
That was my test area. In the living space, we have some vertical joints, which will later be filled with the same material in concrete gray. Now at least I know what doesn’t work or how it doesn’t function.

A lot of overhead work – I hope the muscle soreness stays within limits.
