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)

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

By the way, this discussion belongs in the thread “Dream Floor Plan”
That would be this one: https://www.hausbau-forum.de/threads/eure-lieblingsgrundrisse-von-efh.32165/

In this context, we come back to the question: architect for designing, general contractor for execution? Or just a general contractor?
This topic was also discussed a few days ago: https://www.hausbau-forum.de/threads/Generalunternehmer-ja-oder-nein.32229/

What speaks against continuing with this approach? I quite like it already.
With a few adjustments, it could also meet all your requirements.

An island kitchen can be realized by moving the dining room slightly to the left, which means losing some covered space but gaining room for the island.
Upstairs, the bathroom can be slightly reduced in size to enlarge the master bedroom a bit. Sketch to follow.

It even works with a pantry. I forgot to draw the door leading to the living area. A glass sliding door could also be an option here.
If the pantry is not needed, the hallway can be widened while making the bathroom narrower but longer, or the staircase could be shifted to the right to enlarge the living room...
This design definitely has potential.

Ivenho is also very nice. Stylish kitchen. I wanted to place the fireplace there as well, but then it would have to run through the kids' room.

@Notstrom: Just don’t lose hope; your floor plan has actually gained quite a few supporters now, aside from a few minor changes.

Hello everyone,

Very nice floor plans; we saved them right away.

By the way, we just received an invoice from the architect for 13,200.00 EUR. He accepts the termination of the contract, although he does not agree with the reasons given. He intends to charge us for his fees accrued so far based on our verbal flat rate agreement of 55,000 EUR.

Is this legal? My understanding is: a) there was no written offer, b) no signed contract acceptance, and c) all drafts were not as we wanted; we had to request numerous revisions, yet the quality remained poor. This seems like a tactic to me.

What do you think? What is the legal situation?

He worked for you, you will have to pay.
