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

You’re right, probably also “because.” But whether the forum likes a floor plan or not, the goal is that the homeowner ends up living there and thinks, “Perfect, I feel comfortable and wouldn’t change anything in hindsight.” Unfortunately, reality is often different (I know this from people I know—and most of them had an architect). Someone should start a thread called “What I’d do differently next time,” I’m sure there would be many posts.

The forum shares this goal. Often, it’s the many little suggestions that really help make it perfect. Small details like positioning the door so there’s space for a closet behind it, or doors being too narrow to open properly, or lacking a coat rack.
It’s up to the user which advice they accept, apply, or ignore if not suitable. And yes, sometimes it takes a bit of bluntness for the message to get through—for example, that the dining area doesn’t work because two people get roasted by the fireplace.

By the way, great first post of the floor plan.

There are similar threads. But from a psychological perspective, I don’t think it’s a good idea. Why should one dwell on mistakes later on to the point they get fixed in your mind and cause frustration? Brief reflection or writing down the “mistakes” are two different things.

It’s up to the user what advice they accept, apply, or ignore as not fitting. And yes, sometimes it takes a firm approach to get the point across, like the dining area not working because two people get uncomfortably warm from the fireplace.

By the way, great first post with the floor plan.

I agree. It’s often the little things.
It becomes a problem when someone with no skills draws something and considers it their dream design. Then those are no longer minor issues; a reality check is needed.

By the way, this discussion belongs in the thread “Dream Floor Plan.”

Dear community and everyone following this discussion: Thank you very much for the valuable advice and contributions; they were all educational and informative.

In summary, our architect ended up being dismissed, but I think there were some valid points that we simply would not have recognized without this “virtual sparring.” We borrowed a lot from the drafts created here and believe that with them we will reach our goal. Why do we still think the architect is not the right fit? Honestly: The designs from people like Yvonne or Würfel* were so much closer to our wishes and the overall concept was so cohesive that we asked ourselves: If a community can put this together, it has to be a minimum requirement that an architect can do at least as well. If they can’t, they must go. There were so many errors—walls where they shouldn’t be, recesses without purpose... even the vestibule: with the old floor plan and the wall by the staircase, he did not meet our desire for privacy screens in the living room without a second door (which obviously is problematic when more than one person is in the room...), not to mention the somewhat more acceptable floor plan that we presented with our template. For the price, that was simply not enough.

In this context, we are also revisiting the question: architect for design, general contractor (GC) for execution? Or just a GC? Well, some say that with a GC you pay the architect’s fee one-to-one, but well... For now, we will take a step back and not force anything. We have rented a temporary apartment for two years and will take a more relaxed approach going forward.

...and a big thank you to Katja and everyone who actively contributed. You have been a great support in solidifying the ideas and wishes.

Until now, I always thought we had a clear idea / vision...
