Utility garden, greenhouse: kindergarten ;-)
Other wishes/special features/daily routine, also reasons for why this or that should or should not be included

House Design
Who designed it:
Do-it-Yourself
What do you like most and why?
That it was possible to arrange spacious children’s rooms and create space for two bathrooms. Public living areas on the ground floor, children’s floor on the 1st floor, and parents’ area on the 2nd floor.
What do you like least and why?
I’m uncertain about the positioning of the bathrooms relative to each other (complexity due to drainage pipes), and which staircase best serves the 1st floor layout. The building volume is still not ideal, but I have no further ideas on how to meet the zoning requirements.
Price estimate according to architect/planner: 640,000 EUR
Personal price limit for the house including fittings: approx. 700,000 EUR
Preferred heating system: geothermal

If you have to give up something, which details or extensions
- can you do without: additional room in the setback floor, terrace in the setback floor, already gave up on double garage as it overly restricted the floor plan :-( possibly external basement stairs
- cannot do without: 4 large children’s/teenage rooms, setback floor because we can’t fit all rooms on just 2 floors, basement as a lot of stuff accumulates with 4 children...

Why is the design like it is now? For example:
Because after many nights of planning I couldn’t come up with a better solution...
What makes it in your opinion particularly good or bad?
It meets our requirements on paper, but I lack the experience to judge whether it will work well in practice, which is why I’m asking for your opinions.

What is the most important/basic question about the floor plan in 130 characters?
How can I best organize the living space (especially but not only the 1st floor) and use the proper staircase design to create a spacious hallway without wasting area?

That was quite a bit of work ;-) I hope this information is useful for the further discussion.
In the next post I’ll share the floor plans and some exterior views (if I manage the attachments...)
Thank you in advance for your time reviewing this and for your honest and constructive feedback on the current design!

Best regards
Stephan

Hello Stephan,
Regarding your three main questions, which are anchored in the ground floor: no, no, no.
Well, I’m not entirely sure about the balcony, but who really needs a balcony except maybe for smoking.
Furthermore, the floor area ratio / plot ratio is already quite generous, so hardly any arguments seem reasonable (it would be different if a floor area ratio of 0.2 only allowed 100 m² (1,076 sq ft) and you already lived there, now expecting twins and needing to expand the house. That would be a social factor that might justify an extension as a remodeling measure permitting additional building). But that’s not the case here!

Parking spaces arranged in tandem are usually not allowed.
A carport built up to the boundary, rotating the utility room, using part of it behind the carport also as boundary development, utilizing the exposed corner in front of or next to the house as a parking space – these options are possible.
Keep in mind: 100 m² (1,076 sq ft) of living space costs about $220,000, basement $100,000. Every balcony, recessed area, or roof terrace adds extra costs.
Four children don’t need two bathrooms, a house for six doesn’t need four toilets.
Children don’t need a balcony, and 15 m² (161 sq ft) is enough. Costs easily add up to $700,000 if you include every little luxury. Then it can still become a cool house. The concept is there!
Is the basement still just a utility cellar? A playroom? Where will the office be?
Where does the architect come into play?
Edit: I confused the office with the utility room 🙄
