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

Wir leben Haus also builds custom homes. There are no glossy brochures and no pre-sale agents involved.
However, they use solid wood construction and meet KfW 40, 40 Plus, and Passive House standards.
Mr. K. himself has three children and will probably understand your needs better than a childless snob trying to sell a bathroom waterproofing system to a housewife.

We live, our house is also custom-built.
And then they just drive 300 km (190 miles) to the construction site in Bochum? 😉

You’re welcome. By the way, the (junior) boss also has kids but is a BVB fan. 😉

They don’t just build within sight of the church tower.
Heilbronn, Munich, Wolfsburg,

From what I know about the company, a project has to be appealing. They don’t just demand standard catalog item page 17 here.
