Homeowner Requirements
Style, roof type, building type: Bauhaus style, flat roof
Basement, floors: Basement yes, ground floor, upper floor
Number of residents, ages: 3 people, potentially 4: 33, 30, 2 years old
Space requirements on ground and upper floors: Initially planned 180 m² (about 1,940 sq ft) on two stories, now reduced to 160 m² (about 1,720 sq ft) after feedback, with the ground floor slightly larger than the upper floor, around 75–85 m² (810–915 sq ft)

Open or closed architecture: Rather open
Conservative or modern construction: Rather modern
Open kitchen, cooking island: Island
Number of dining spaces: 1
Fireplace: Yes
Music/sound system wall: Our soundbar is sufficient
Balcony, roof terrace: Maybe, undecided (Architect’s comment: How often do you really go out for a beer on the balcony/roof terrace instead of the nice terrace on the ground floor?)
Garage, carport: Double garage, possibly single garage with carport
Kitchen garden, greenhouse: Small but nice (a few tomatoes, cucumbers, zucchinis…)

House Design
Planning by: Architect

What do you particularly like? Why? We like the architecture with the two offset rectangles, though we wonder if the extra cost (no price estimate yet) justifies this. We believe it is structurally more challenging than a simple "cube."
What don’t you like? Why? The size of the bedroom/walk-in closet/children’s room. It feels like the bedroom is missing 2–5 m² (about 20–55 sq ft), as is the second children’s room.
Price estimate according to architect/planner: The initial draft was around 550,000 EUR
Personal price limit for the house, including fixtures: 620,000 EUR
Preferred heating technology: Indifferent, but tendency toward heat pump.

If you had to give up something, which details/finishes
- You can give up: the current shape (nice but a cube would also do)
- You cannot give up: space

Why is the design the way it is now? For example:
Standard design from the planner? This is the second design resulting from last week’s discussion with us, and we find it very successful.
Which wishes were implemented by the architect? Absolutely, plus the idea he had to move the kitchen during development. The guest room has now moved to the basement, allowing more space on the ground floor (beforehand, it felt quite cramped and “squeezed”).
What makes it especially good or bad in your opinion? The architecture

...and now I’ll leave you alone with our house

I would personally move the kitchen door closer to the entrance, prefer to have only one door in the bedroom, and swap the bathtub and the sink in the bathroom. I would place the sink on the wall next to the bedroom and extend it nicely.

Why don’t you access the bedroom through the walk-in closet? That would be much more practical...

I like the ground floor as it is, but for the upper floor, I would actually consider giving the second child some balcony space as well. That could cause some issues, though—if a second child is even planned and the room isn’t being used for something else.

I would swap the sink and bathtub because of the natural light. Having light at the washbasin is really practical and more necessary than near the bathtub. Access to the walk-in closet has already been mentioned—I would prefer that over going through the bedroom, but I guess that’s a matter of personal taste. Otherwise, I really like the overall layout.

It seems I have missed quite a bit. By now, you have also switched to a gable roof?

Personally, I find accessing the space through the walk-in closet rather impractical and would have done it the same way as the original poster. I also quite like the room layout and sizes on the upper floor. However, as already mentioned several times, I would have preferred to keep the hallway open on the ground floor if possible.

What I also don’t quite understand is why you are saving on ceiling heights with just under 2.5 meters on the ground floor and 2.23 meters in the basement? If I have read it correctly, you even have 1.1 meters of additional height available according to the building regulations/planning permission?

So, the walking routes have been roughly marked for both layouts:
blue = coming in at night
purple = getting into bed after undressing
red = getting clothes in the morning
pink = leaving in the morning
I hope the routes are clear and that you can see how often you might disturb a partner who is still sleeping in one layout compared to the other

It's a pity that you are now going ahead with the walk-in closet... Was our input here not clear, or is it a conscious decision regardless of any arguments? In that case, there's no need to discuss it further.
