ᐅ Floor plan design shortly before submitting the building permit application

Hello everyone!

As some users have requested before, I’m now starting a new thread with the current planning of our detached house, which is about to be finalized.

These are the preliminary drawings for the building permit / planning permission application, and I have one last chance to review them and point out any issues.

It still seems to me that there is less than 1.20m (4 feet) of space between the two wardrobes in the dressing room. Or am I seeing this wrong? Apparently, the rooms on the left and right were overlooked and not adjusted accordingly.

Two Velux ceiling spotlights are still planned to illuminate the upper floor hallway.

In the basement, on the right side in the upper room, a window similar to the one on the left basement side is an option.

We still haven’t decided on the T30 fire-rated door to the garage, even though it is shown in the plans. Most likely, for safety reasons and the limited use of the kitchen at the other end of the house, we will eventually forgo it.

User 11ant pointed out that the right window in child’s room 2 is suboptimally positioned. However, this could still be changed after submitting the building permit / planning permission application. Our architect thinks moving the window to the left would negatively affect the house’s exterior appearance. We’ll have to see about that.

They also had a dispute regarding the building insulation. The issue was whether the perimeter insulation should be placed in front of or behind a certain membrane. Please don’t ask me... The expert report is still pending. In any case, the site manager said it probably doesn’t matter, while the expert argued that the DIN standard specifies how it should be done and that it is justified.

There are several damp spots in the basement. For now, these are just being monitored to determine whether it’s residual moisture or something else. At some point, I posted a photo of a crack in the concrete ceiling of the basement (either here or in the house photo thread). The site manager said it’s not a big deal. The expert, however, found it serious and is demanding remediation.

There was an issue with ventilation in the roof structure. According to him, the air does not vent properly, and if nothing is done, a mold cavity could develop there.

The roof eaves are partly not up to standard in terms of wood quality and installation (gaps between individual elements).

He criticized that there aren’t L-brackets or similar fasteners installed every 7cm (3 inches) at the windows. This led to a conflict with the window installer, who was also present on site. The window installer was asked to provide written documentation regarding the windows and roller shutter boxes.

In the garage, the ceiling is sagging downward.

I’m looking forward to the report and especially to how the general contractor (GC) will respond and what actions they will take. The GC’s expert will inspect the site on Wednesday.

I wish you steady nerves.

Your independent expert will be right on most points. That’s why you have a counter-expert. I wouldn’t give much weight to what the site manager says, as they tend to dismiss everything.

The ceiling in the garage was apparently formworked and poured incorrectly. When pouring, the ceiling should be slightly convex upward to prevent sagging later.

Is your general contractor a well-known company or a local firm?

Well, the inspector seems to be reviewing all trades involved. Just be careful that nothing gets unnecessarily complicated or overcorrected – I have seen this happen firsthand with an expert who quoted many standards but was not very pragmatic on certain issues.

How am I supposed to be careful? It has always been recommended to have an independent expert involved in a general contractor (GC) build who is not connected to the GC. If this expert now tells me that the insulation is incorrect and can prove, for example, that a vapor barrier should have been installed on the inside instead of the outside, then I have no choice but to accept it. Otherwise, what do I need this expert for? He also says that if a digger hits it once, the insulation is ruined. And that DIN standards are justified and cannot simply be disregarded.

Regarding the emergency exit, I found the following in the building permit / planning permission application.

Floor plan of an apartment: Bathroom with bathtub, dressing room, bedroom, roof terrace, and emergency exit.


It’s interesting that for the fixed window element in the dressing room, the height of 2.01 m (6 ft 7 in) is explicitly declared as measured from the finished floor level, while this is not the case for the three doors. If there are differences here, won’t it look different visually in the end, or am I mistaken? This is how the whole thing was visualized after all.

Hi,
I would also tend to trust the inspector and the DIN standards in this case. It’s unfortunate that there’s so much to address. Maybe the inspector should visit more frequently?

We have a total of 7 appointments (I believe), and the meetings are held with the site manager, the expert, and sometimes with the subcontractors as well. There have been quite a few issues, but everything is always noted politely by our construction management. Afterwards, they take care of the repairs.
We had: missing loops on the outdoor water faucets, broken roof tiles, missing shimming under the window sills, incorrect parapet height in the bedroom, and waterproofing at a low-level terrace door not done according to DIN standards.
These were recorded and fixed without any complaints.

I think it’s “normal” for some things to go wrong occasionally. I would talk to the expert and then politely urge the general contractor (GC) to repair whatever needs fixing.

For example, our parapet height is still incorrect. But since the window and roller shutter were already installed, the expert said it didn’t make sense to fuss about a few centimeters (inches). That was fine with us.

He will be back in two weeks before the plaster and screed are applied. I also told him that I am willing to hire him for more frequent inspections if it makes sense. He said the initial walkthrough went so well that even he is surprised.
