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

However, it might be worth checking if, by shifting the walls on the upper floor, it is possible to have the chimney flue on the ground floor located internally rather than externally. This could be well concealed with the fireplace. I would prefer that over the awkward corner on the terrace.

It’s best to leave out the fireplace entirely. It only has disadvantages. :P

I like it overall except for the windows and the elevations. I would completely revise those in a quiet moment.


The windows are not ideal yet, we are aware of that. What do you mean by “elevations”?

…just to fill my gap in experience: what are the disadvantages of a stove? With so many likes on your answer, I’m very curious now.

Is direct access to the walk-in closet from the bedroom important to you? Otherwise, I have an idea with access from the hallway, and then the children’s rooms would not have those awkward corners.
The walk-in closet seems rather like a “walk-in wardrobe” in terms of width, no criticism intended, we have the same. The actual dressing usually takes place in the bathroom. Since you have to go through the hallway anyway to get to the bathroom, I wouldn’t see a drawback in not entering the walk-in closet through the bedroom. But as I said, it’s a matter of personal taste. This way, the walk-in closet would still have about the same amount of usable space, and the children’s rooms would benefit from the hallway.


Thank you

If I try to put it objectively, I’m at a loss: it just feels to me that the floor plans are more clearly structured than the elevations.

I would first develop the windows from the interior perspective, meaning starting from the question “where and how much light do I want?” and then working backward to “where does it need to come from and in what size.” The answer is usually already quite dynamic, and combined with a cube arrangement it can easily become excessive.

Well, first of all, a fireplace creates mess. You get dirt from the ashes, from the wood which might even harbor some insects, and of course, you constantly have to clean the glass door.
Then, the thing is expensive. The initial purchase costs have to be covered, the wood needs to be brought in, and the chimney sweep also requires regular payment. Additionally, it takes up space in the house that could often be used more efficiently and costs money.
Furthermore, during storms (which we have regularly now), the chimney makes noise. I haven’t experienced one that doesn’t howl or hiss in strong wind.
As an environmentally conscious parent, you probably don’t want to pollute the air with completely unnecessary CO2, right?! ops:
The biggest drawback, however, is that in homes built to the energy saving standards (which applies to all new constructions), the desire for a cozy, snug fireplace just doesn’t arise anymore. It’s already warm and comfortable. There are no drafts, no cold spots, no damp corners, or uninsulated roofs. On the contrary—a fireplace would cause heat buildup that’s hard to bear.
Result: the stove remains off 99.9% of the year.
