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

I see strong parallels with our floor plan. The upper floor in particular is very similar.
You might want to take a look at the plans...

I like it except for the windows and the elevations. I would take some quiet time to completely revise those.

In addition, I would:
- add an extra door from the hallway for a shorter route to the kitchen, and
- widen the hallway area near the children’s rooms at the expense of Child 2’s room, so there is enough space to fit a wardrobe around the corner.

Well then, we’re curious

That’s true. Do you also have simplified versions of the drafts? I still find the working drawings hard to understand.

Is direct access to the walk-in closet from the bedroom important to you? Otherwise, I have an idea for access from the hallway, which would also allow the children's rooms to be free of those awkward corners.

The walk-in closet seems a bit narrow to me, more like a "walk-in wardrobe," which is not a criticism—we have the same. The actual dressing usually takes place in the bathroom. Since you have to go through the hallway to reach the bathroom anyway, I wouldn’t see any disadvantage in entering the walk-in closet without going through the bedroom. But as I said, it’s a matter of personal preference. This way, the walk-in closet would have roughly the same amount of usable space, and the children’s rooms would benefit from being connected to the hallway.

Oops, a little misunderstanding. I meant that I would revise it if I were you. Sorry, I didn’t mean to give false hope—you’ll have to tackle that yourselves.

then the kids’ room without those weird corners.
That was my first thought too, but the chimney is difficult to move and is actually well placed there against the wall.
