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

Somewhat... but probably not anymore.

What do you think about this?

Hello everyone, before ordering the windows, I have a question for you:
I have developed a few ideas regarding the current plan.

Alternative 1:
- Align the “right side” by increasing the height of the guest WC to 1.25 instead of the previous 1.00
- Align the “left side” by adjusting the window heights to 1.00 instead of the previous 0.75 from the bathroom





































# What Previous New Comment
208 Guest WC 1.00 x 1.00</TD]

1.00 x 1.25</TD]

Match bathroom 302</TD]
202 Kitchen 2.00 x 1.00</TD]

2.00 x 1.00</TD]

No change</TD]
303 Bathroom 1.65 x 0.75</TD]

1.65 x 1.00</TD]

Adjust kitchen 202</TD]
304 Bedroom 2.00 x 0.75</TD]

2.00 x 1.00</TD]

Adjust kitchen 202, bathroom 303</TD]


Alternative 2: Adjust the height of all windows on the front facade to 1.00, including the bathroom. This way, there would be only one consistent height dimension throughout.

What do you think?

I think this makes the whole design look very busy. Are these really 5 different window sizes? Couldn't it be limited to two, with one being wide and the other tall?

I believe that aligning all windows evenly is nonsense, but I would make one window in the basement narrower (the same width as the one next to it) and shift some windows on the ground floor and upper floor to the right:

That sounds reasonable, but making the basement window smaller would significantly reduce natural light for the home office...
