ᐅ Single-family house floor plan, 2 full stories, approximately 180 m², on a 600 m² plot of land

Hello dear members,

like most others, I have also been quietly following along for quite some time. There are many great pieces of advice here.

The building application has been submitted, and the exterior dimensions as well as the number of windows are fixed. Positioning is still negotiable in consultation, though only to a limited extent. Inside, we basically still have almost all options. The general contractor (GC) is a local family business and has been operating for over 20 years. They are consistently found in the surrounding new development areas, along with two other GCs, and their reputation is quite remarkable. (In fact, we spent quite some time interviewing the newly settled homeowners around us... *g*) One GC was excluded because of the building method (exclusively KfW 40+ standard), and another after submitting a proposal. The process so far has taken about 10 months, starting with graph paper, heating technology, necessary rooms, house positioning, and so on. There are great guides on this topic in the forum!

So, I hope these words were inviting enough to read through the list of questions. If I have forgotten anything, please let me know. I look forward to your feedback, critical comments are also welcome!

House design
Who created the plan:
Planner from a construction company, based on our draft floor plan
What do you particularly like? Why? All necessary rooms are present in sufficient size
What do you not like? Why? Office entrance difficult to use, lack of space due to guest WC and living room widening
Fixed price: approx. 450,000€
Personal price limit for house, including fittings: 550,000€
Preferred heating technology: air-to-water heat pump + underfloor heating

If you had to give up something, which details/extensions:
- can give up: size of the dressing room
- cannot give up: office / two children’s rooms

Why did the design turn out like it is now?
Which wishes were implemented by the planner?
- We have already planned and commissioned the kitchen; floor plan adjusted accordingly (changes still possible)
We hesitated a long time over open vs. closed kitchen and, after deciding, debated for a long time over whether to have a pantry behind the kitchen front or not; it is now behind sliding elements on the right side (see attachment)
- Storage space under the stairs
- Bedroom window removed on the east side because of bedroom closet
- Living room widened due to TV wall and to gain space
What makes it particularly good or bad in your opinion?
All rooms are suitable for everyday use, and living on the ground floor later with minimal alterations is possible

What is the most important / fundamental question about the floor plan in 130 characters?
Are the individual rooms adequately lit? I have no sense of this at all. Any obvious flaws?

PS: North is at the top on the site plan as well as on both floor plans!
