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!

House Design

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?)?

Site plan: two blue building outlines, red access areas, yellow border area, row of trees, north arrow.


Floor plan and site plan with color zones; inset apartment floor plan in center.


Ground floor plan with living/dining/kitchen, hall and utility rooms of a house.


Upper floor plan: sleeping, two children’s rooms, bathroom, shower, hall, walk-in closet, sauna extension.


Attic floor plan: two rooms, stairs, flat roof, measurements, entrance doors.


North elevation of a two-story house with gable roof, windows, and person in front.


East elevation of a modern house, gray facade, dark roof, tree left, person in front.


Two-story house with gray front, large windows; person left, bush right; south elevation.

That's correct, Miele refrigerators are made by Liebherr. But Miele sells them at a lower price.
Oh wow, I didn't know that. I've never compared the prices, I just assumed Miele is always more expensive.

That doesn’t look like a hospital at all.
But I think I know what is bothering your wife.

Doors can be removed, with all the pros and cons.

Make the kitchen, dining, and living area more open—no doors and no tunnel effect.
Building services above the garage—means there is no storage space inside the house.
Office in the entrance area—there is no coat rack or storage space.
A toilet is necessary.

A lot of things go unnoticed because the eyes and mind are focused elsewhere. I notice this with our guests when they look for the toilet. Everyone walks right past it. Hardly anyone registers it. Their attention is somewhere else.

What do you mean?

She doesn’t like the hallway with all the doors, quote: “You enter through the door and it feels like a hospital, nothing but doors on the left and right…” oops: She prefers the design from the main contractor (without the useless windbreak area) because in the entrance area there is only one door (to the home office) and the doors to the utility room, HVAC room, and pantry are “hidden” in the back hallway… However, I don’t really believe all those corners are necessary for that

There are alternatives, not just these two.
Designing a house takes several weeks and is either developed step by step or starts over. It’s not an either-or situation.

Did you have the overall dimensions of the plot including the building envelope and driveway available?

I am actually quite confused about the garage’s location on the street. Since when is something like this allowed? However, due to time constraints, I haven’t read much and only looked over the plans briefly... Unfortunately, I noticed another case of simply lining up rooms. Personally, I am missing the plot dimensions!

Wow! You can even look that up online.
I’m a bit shocked that something like this still exists: the WAF assumes that the man decides, chooses, or plans something for himself, and then the woman gets to give her opinion on that purchase.
