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)
Office: Family use or home office? Yes, in the basement (guest room <-> office)
Overnight guests per year: Hard to say, probably about 10 times per year with 2–5 guests each time
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

But maybe that’s also because our living/dining area is 52m² (560 sq ft) and open to the hallway and upper floor.

Yes, well, if you have a mansion with several open floors, that probably changes the perspective.

For me, it was more about the desire for a fire not arising. When I think of the cold houses from the past, I would have liked to have a fireplace. But now the house is so cozy and warm, why have a fire? I’d rather look into the aquarium – it’s greener. :P

Even if you say it with a wink, I understand something different by a mansion.

A fireplace is a "luxury," and there are people who gladly spend money for it, accept the dirt, enjoy cleaning the glass, hauling wood, etc. And there is no need to discourage this here just because some users have a different opinion on the subject.
This has become more noticeable lately; I remember how an architect user was criticized here even while still in the early planning stages.

I also look at the aquarium, and I curse the thing because it creates more work and mess than my fireplace.

Dude, the original poster explicitly asked for my opinion—not yours.

I have now stoked it for the third time. The temperature on the ground floor is 24.2°C (75.6°F).

@Notstrom I really like the new design.

Very nice fireplace.
What is its nominal heat output?

Well, fireplace. More like a small stove, actually. But that makes sense, since it realistically won’t have more than 6-7 kW (20,400-23,800 BTU) of output.
