Hello everyone,

We have just purchased a plot of land and are now at the stage of planning our house.
After two initial attempts at designing it ourselves without much success, we have now met with a structural engineer who helped us create a floor plan tailored to our needs.
I would like to share this design here for discussion.
We have already chosen a local builder. The plan is for a timber frame house with solid wood interior walls and a timber frame exterior wall filled with blown-in wood fiber insulation.
The entire house is intended to meet the KfW 40+ energy efficiency standard eventually.

The architecture should be modern, bright, with an open living/dining/kitchen area.

- We currently favor a gable roof with a 22° pitch.

Why did the design end up as it is now?

We wanted to make the best possible use of the plot.
Basically, we would have liked to orient the terrace towards the southwest, but unfortunately, there is the street there, and I don’t want to be completely exposed.
Also, the west side is the weather side with a lot of wind.

What do you think makes it especially good or bad?
???

What is the most important/fundamental question about the floor plan in 130 characters?
What do you think of the design, and what could be done differently?
We might want to redesign the bathroom, maybe a T-wall?
Would you change anything about the window layout?

We would appreciate any ideas or constructive criticism very much.

The door to the utility room works without any issues.
The door to the pantry will still be changed – we will access the pantry from the hallway instead of through the kitchen cabinets. Additionally, the pantry will be about 15cm (6 inches) wider.
The second door to the garage is intentional. I don’t want to have to go outside every time I enter the garage in the evening or at night.
The 15cm (6 inches) step is also by design – this helps to keep leaves and dirt inside the garage. (This was also recommended by the architect.)
We are aware that the bedroom is narrow, but we manage very well with the same dimensions in our current apartment.

- Why are there two doors leading to the garage? I would remove the door from the cloakroom and use all the space for the cloakroom. You already have a small canopy in front of the main entrance, so you won’t get wet there. Are you aware of the 15cm (6 inches) step up into the garage?

I would remove it as well; the path through the main door is not long and more pleasant, and the space in the cloakroom is valuable. See if you can fit a large closet in there.

That sounds a bit odd. What are you doing in the garage at night? Do you leave the house completely after a quarrel?
The door really seems unnecessary. But it’s not a huge issue. If you notice it, you could simply place a cupboard in front of the door.

Overall, it’s an improvement and also a budget-friendly advantage due to the reduced size.
I would keep the access to the pantry through the kitchen, arranged like this:

Otherwise, it would mean a lot of running back and forth for every single potato or onion you need.

I also find the bedroom too tight as it is. I would rotate the bed, skip the floor-to-ceiling windows, and place a sideboard under the window instead of having a wardrobe in the middle of the room. But I guess the windows are more important to you, and you prefer to squeeze along the wall.

The conduits to the utility room will probably be at their maximum length this way, right?
It’s also a pity that the east elevation is a bit skewed, but okay, that’s manageable.

In my opinion, the ground floor lacks the full potential for a dream house, but if you like it this way, why not?

If you like your design as it is, then build it that way.

I really don’t like the entrance to the utility room under the stairs at all. Especially since you need to go in there often, as it’s your only storage space. I would prefer a door with an angled corner, and I’m not a fan of having it pass directly under the stairs either.

The door could also open outwards.

The idea with the pantry is nice, but with your proposal, I don’t get enough tall cabinets in the wall.
The plan includes a side-by-side refrigerator, a tall cabinet for the oven, and at least one pantry cabinet (my wife wants that). Unfortunately, that wouldn’t fit like this.
The floor-to-ceiling window in the bedroom should definitely stay, otherwise it would ruin the whole south-facing look.
Maybe a bit of space could be taken from the office.
We are aware of the east-facing side, but it wasn’t possible any other way.
Besides, this side is not visible, so it can be neglected.

What do you mean by long lines to the utility room? Don’t I always have them?
I can hardly plan the utility room in the center of the house.
