Hello everyone,
My wife and I are planning to become homeowners soon and have had a preliminary floor plan created by our (prospective) prefab home provider based on our first meeting.
We have a specific plot in mind, but the new development area is still being surveyed, and the parcels are being reorganized. Therefore, there is no official site plan yet, only the attached zoning plan excerpt (dashed lines = property boundaries).
We find the floor plan draft interesting at first glance, especially since it doesn’t seem like a standard template from the provider, at least from our perspective. I’ve listed a few points below that I think could be improved – I’m sure you’ll notice more...
Thanks in advance for your assessments!

What Do You Like Especially? Why?
Ground floor: open living/dining area but no direct line of sight from sofa to kitchen, short route from front door to pantry, separated utility room
Upper floor: separation of children’s and master areas, no “trapped” walk-in closet, roof terrace, “sleeping platform” in children’s room
What Do You Dislike? Why?
Overall: floor plan looks very elongated
Ground floor: entrance vestibule (in my opinion unnecessary), coat storage far from front door (alternative under stairs?), WC possibly too narrow, no direct access from kitchen to terrace (planned at SE/SW corner – around the corner), seating nook in kitchen (planned to be removed/replaced with window seat), distance between kitchen island and wall, narrow passage living/dining area if fireplace and piano (175 x 60 cm) are placed as planned
Upper floor: children’s rooms facing north, bedroom facing south, “space” at roof terrace exit, overall space usage (large hallway 20 sqm plus 10 sqm “leftover” as “sauna room” (sauna for 2 persons should be integrated in bathroom), bathroom rather small and walk-in closet quite narrow)
Price Estimate According to Architect/Planner: $465,000 (excluding land and additional construction costs)
Personal Price Limit for the House, Including Equipment: $500,000
Preferred Heating Technology: air-to-water heat pump, possibly with photovoltaic system
If You Have to Give Up Anything, which Details/Features
- Could You Do Without: sauna, kitchen island, roof terrace
-Could Not Do Without: fireplace, office/guest room, separate walk-in closet/dressing room, 2 bathrooms upstairs
Why Is the Design Like It Is? e.g.
Standard Design from Planner? – no
Which Wishes from the Architect Have Been Implemented? – design based on our room program and “wish list” (e.g., fireplace, “window seat” in kitchen, spatial separation of living room and kitchen, no trapped walk-in closet)
What Do You Think Makes It Especially Good or Bad? – bad: space use upstairs (20 sqm hallway + 10 sqm sauna/leftover space), good: separation of “technical area” on ground floor and children’s/master areas upstairs
What Is the Most Important/Basic Question About the Floor Plan in 130 Characters?
Can this initial draft be developed further, or is it better to start from scratch? If the latter, how to improve (classic rectangle?)?

So, I tried designing a double carport (since the 1.5m (5 feet) rule only applies to garages) with an entrance facing northeast... Great, thank you very much for putting so much effort into this! I can clearly visualize the carport and especially the storage room behind it (if it’s allowed directly on the street, see the discussion above). However, I share your concerns about a complex upper floor layout. Having the main terrace facing southwest would indeed be desirable – whether the office is on the ground floor or upper floor doesn’t really matter to us.

I think you are referring to that—but I wouldn’t assume it applies to a single-family home. I am quite sure that it does apply to a single-family home because the parking space regulations do not mention "single-family home" but only "residential buildings [...] with up to two apartments." Therefore, I consider a single-family home as a residential building with one apartment, so paragraph 2 should also apply here. But as I mentioned before, I just need to clarify this with the local authorities.
Buying out parking spaces is also possible according to the regulations, but it is not very cost-effective (10,000 euros per parking space), and I would prefer to have two parking spaces if it is feasible...

How important is the pantry? Was it created just because there was some extra space, or because you specifically wanted one? The usefulness of having a pantry in modern houses has been widely debated here as well..We would like to have one, at least for bulkier items like beverage crates, milk cartons, etc. The food supplies could stay in the kitchen cabinets for all I care (but my wife prefers to have everything in the pantry).

I don’t want to start a pantry debate, just a quick note:
in a modern house, the pantry never really gets cold. Not even unheated in winter. Actually, if you have geothermal heating with a cooling function, you can cool in the summer and simply open the window in winter (which is, of course, a must). It works perfectly.
