Our concern is that it will become uncomfortable if the hallway leads directly into the kitchen and living room...
My concern is that this 3.62-meter-long tube rather spreads some discomfort. I also don’t necessarily see both walls as necessary for the statics. Not like that. And if so, the top storey must also cooperate.
The walls don’t do well, they are somehow pure arbitrariness, they look as if a plan either still has to start there or stopped abruptly. The offset to the "bay window" in the south also doesn’t fit the flow of the walls. If you use the room there in the living room by the window, you look at the wall edge... that doesn’t create a nice spatial impression.
This little corner behind the stairs irritates me. Why isn’t the staircase placed bright and open on the west side, where it can get proper daylight and reach three floors adequately?
In the upper floor, there is a leftover room. It is funny and nice that the shower on the ground floor resulted that way, but I would rather place the stairs on an outer side where it gets daylight from the upper floor. A shower can be arranged differently. I wouldn’t hold on to that, because it doesn’t do the stairs any good.
Why is there only one window in the west? I don’t find the windows harmoniously distributed at all. The house now has the character of a row house this way.
The wardrobe is too small for 6 people... The front part of the hallway can’t be used for furniture (bad door position), only the mentioned walls offer space for a sideboard and key rack. The doors on the upper floor are also somehow arbitrary... at least on the west side they all could get a push ;)
The windows of the top storey facing south are not sensible either. That might be convenient, but a south window in the bedroom, moreover a big one, especially since it lacks harmonious east and west windows, I don’t approve of that.
How was it with the excessive boundary development? That’s not allowed, is it?! Or is it?
but we did use it to have our design thoroughly checked by an independent architect.
You only have the architect check it? You do the planning yourselves?
The general contractor plans with 19 cm floor buildup on each floor, the architect says 15-16 cm should suffice.
What role does the architect play here? Who commissioned him? The general contractor or you?
Can every roofer do this or do you need an expert whom a general contractor probably doesn’t have/wants to pay?
If you plan to build with a general contractor you shouldn’t overestimate his skills or those of his craftsmen/subcontractors. Turnkey prices are for a standard that doesn’t overstretch the interfaces between trades.
If you have other advisors like an external architect who encourages you to build differently, then you shouldn’t build with a general contractor.
All the mentioned inconsistencies suggest that maybe you should have the architect plan rather than just have him check.
