Floor plan of a flat-roof house on a slope

- I don’t really like the entrance situation. Does the laundry room have to be such a palace? I would probably make the laundry room smaller and the entrance bigger instead.

- Why do you heat with oil? Unusual nowadays.

- I also find the access to the boiler room unfavorable, the bottleneck at the boiler is not so great.

- Why a wide floor-to-ceiling window to the terrace if the couch is placed in front of it? Moreover, that is exactly the spot where people sit on the terrace. So you always see the dust behind the couch...

- Why 2 doors in the bedroom? I would probably remove the door to the hallway and only access the bedroom through the dressing room. For that, I would place the head of the bed on the bottom wall of the plan, so the one sleeping by the window doesn’t always have to walk around the entire bed.

Well, then I'll try my luck:

... and I’ll also complain right away:

I would have preferred the light well grate at least in front of the fixed part of the sliding door rather than in front of the exit. Actually, this would even be a reason for me to thoughtfully consider whether it could be solved more elegantly.

Especially in the bathroom, I dislike that the door is so slammed against the wall. In my opinion, the ratio of bathroom area to children’s or bedroom area is skewed. I would widen the dressing room to 2.51 m.

Why should the pantry be removed?

The garage door seems to treat the second car like a stepchild. Also, to avoid scratching it with the bicycles and garbage cans (or whatever the meter beside it is for), I would make the door opening wider to the right (= left side of the plan). And as always, I suggest single doors.

In the upstairs floor, I have slight doubts about the structural integrity.

I am already lacking the will to preserve some opinions. Thanks to we can at least see the floor plans, but the OP still owes us explanations about the WWW: who, what, why.

Well, I don’t think the place is bad. The objections from 11ant are justified and certainly still fixable. Two things that would bother me: 1. If I’m reading this correctly, an oil heating system is planned, and if I’m not mistaken, the tank room is at the furthest point from the street. If that’s the case, refueling it later would each time involve a hose running through the entire house. You’d enjoy the smell nuisance for about a week. But since that usually happens only once a year, what the heck. 2. Personally, I don’t find it cozy, nice, or relaxing to sit under such a block on the terrace at all. It’s more oppressive and threatening. I wouldn’t want that at home. But that’s a matter of taste. If then “someone” doubts the statics, it gets even more unsettling.

The heating room is unfavorably positioned and also massively oversized. Both the size of the room and the storage. 3x1500l should last the house >4 years. 1000l per year is sufficient. If you already want to install an oil heating system in such a new building, then find someone who can do it according to today's standards and not like 50 years ago.

Have you planned a central ventilation system? Then I would eliminate the basement shafts. They look bad from the outside, represent potential leaks, and do not bring any light anyway. Placed in front of the lift-and-slide doors, they are very awkwardly positioned anyway.

KFW55? The wall thicknesses almost suggest this, but with the number of thermal bridges due to the offsets and projections, that might be difficult. The energy consultant will definitely be a few euros more expensive because he has more calculations to do.

The elevations can still be worked on, e.g., on the east side of the upper floor the window formats do not match each other, and the upper and lower floors can also be better aligned (although this does not have to be a top priority).

What bothers me in the living room (but this applies to 99% of floor plans) is that the sofa has its back to the terrace. When I sit there, I want to be able to look outside. But as I said, this is the case in many "modern" floor plans; apparently, there is a consensus to place sofas in front of expensive floor-to-ceiling windows to then look at a wall.

Is there already a price indication for the house? Basically, I like it.
