Penthouse floor plan - Is it that practical?

In any case, I find the entrance area of the Gu-Plan more beautiful, although it is quite large.

More beautiful, no, (too lavish) larger, yes.

So here is the 2nd draft of our GC:



We find it quite nice so far. The GC now wants to provide a cost breakdown - we are curious.
What do you say?

What do you say about that?

...That the walls on the upper floor with 11.5 cm are too thin in terms of soundproofing. Possibly, ventilation ducts may still run through them with centralized controlled residential ventilation.

The chimney should be moved to the corner at the top of the children's room - correspondingly at the bottom.

Thin walls at the top I would also find bad.

[Hauswirtschaftsraum] I find quite large - is it necessary?

Two doors at the passage are annoying - I would leave out the one towards the hallway.

Turn the stairs - would bring less hallway at the top and remove the dirt area from the landing at the bottom.

Ok. So the walls on the upper floor should rather be executed in 17.5? [zentrale Kontrollierte-Wohnraumlüftung] is to be installed. I have to see where the pipes are planned.

Move the fireplace: We'll see. At the moment I don't see it that way because the fireplace would then move further away from the couch downstairs. Especially since I actually don't find it bad upstairs. This still creates a niche upstairs for placing things.

The utility room should be a bit larger, but you are right, 2 m² less wouldn't hurt either. It just happened that way. Maybe we take half a meter off the house width, specifically in the living area. Then the utility room would accordingly become half a meter narrower.

Two doors at the passage: I've already noticed that too. I think we will save one (which is something to save [gefunden]).

Turn the stairs: Very good idea!

Ok. So the walls on the upper floor should rather be made with 17.5? Central controlled residential ventilation is to be installed. I will have to see where the pipes are planned.

Unfortunately, 17.5 lime sandstone is not so generous either. Because it is also mostly hollow inside today anyway... (2-3 vertical tubes).

Execution of the wall on the upper floor presumably as follows: Ventilation duct embedded in the ceiling concrete, then vertically up the wall to the supply or exhaust opening in the room, where a thick "trench" is often made up the wall for this purpose (half a brick width quickly chiseled out with a Hilti; the approximately 8 cm high ventilation duct is laid in the trench, foam and filler over it, done...

From the builders' point of view, there are simply no requirements for sound insulation in single-family houses, only partially in multi-family houses.
