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.

Our construction partner requests that, contrary to this description, no precast walls be used, but rather that the formwork be done on site. This would save time, and the excavation would not need to remain open for long after the groundwork, especially given the bad weather.

Just out of curiosity: why is in-situ concrete supposed to be faster and more resistant to rain, etc.? I must be missing something...

They meant that construction could start immediately after the excavation work. As I understand it, the delivery time for the precast elements is so long that once the excavation is finished, nothing happens on the building site for a while. They don’t think that’s ideal given the weather conditions.

So can I simply approve it like that? They will plaster all the walls. The basement is planned to be constructed as a waterproof shell. That shouldn’t be a problem either?

The basement is planned to be built as a “white tank” waterproof structure. Is that not a problem?

White tank or just waterproof concrete, known as WU concrete?

The recommendation from the geotechnical engineer was a white tank. I was told that this arrangement (WU concrete) covers that. During the contract review by an expert, this was also considered acceptable. Until now, I had assumed this was simply another term for white tank. Unfortunately, the contract text does not specify anything else.

If your geologist recommended a waterproof concrete tank, your site has more than the usual soil moisture. Possibly hydrostatic pressure or a generally high groundwater level. Therefore, waterproof concrete alone is not sufficient, and your soil expert should have recommended a specific design of the waterproof concrete tank in terms of waterproofing and crack width limitation (depending on water pressure) reinforced concrete.

Yes, we also need a light well for the basement window, which must be constructed to be waterproof against hydrostatic pressure.

The report does not explicitly refer to a waterproof concrete tank (white tank system), but it is worded this way (see attachment).

However, it was always assumed that we would build a waterproof concrete tank. I need to clarify where this possible misunderstanding comes from.
