Hello,
we are currently working on the floor plan for our house. We already have the plot, which is on a sloping site.
We have decided to build a two-story house, with the upper floor (sleeping area) providing access to the street and the lower floor serving as the living area with garden access.
We want a manageable house size, but due to the requirements for the living floor, a minimum of about 140m² (1505 sq ft) is necessary. However, it definitely should not exceed 150m² (1615 sq ft).
We want a modern touch or something distinctive. For example, because of the great view, we considered a window seat. Ultimately, we decided on a small open space with a large window facing the backyard.
We really like the lower floor; the ground floor is not yet one hundred percent right.
Since I have been a long-time forum reader, I want to mention upfront that optimizing every last bit of available space is not a must for me. I am aware that, for example, a lot of space is used for corridors. Given the house’s orientation (there are no alternatives here), I think this is necessary to avoid a cramped feeling.
I would appreciate any feedback or suggestions.
And here is the questionnaire:
Development plan/restrictions
Plot size: 700m² (7,535 sq ft), width 20m (66 ft)
Slope: yes, sloping
Floor area ratio: 0.4
Building envelope, building line, and boundary: standard 3m (10 ft) setback
Number of parking spaces: 2
Number of floors: 2
Roof type: hip roof or gable roof
Style: modern
Orientation: northeast
Client requirements
Style, roof form, building type: city villa style with the special feature that, due to the slope, the entrance is on the upper of the two floors. The lower floor is fully embedded at the street side and opens to the back.
Basement, floors: ground floor and living basement
Number of occupants, ages: 4 (35, 35, 3, 1)
Room requirements on ground floor, upper floor: living floor must have at least one (small) room. Living, dining, kitchen combined approx. 45m² (480 sq ft), guest toilet with shower
Guests per year: none
Open or closed layout: open
Traditional or modern construction: modern
Open kitchen, kitchen island: open without island
Number of dining seats: 6-8
Fireplace: no
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: double-level single garage (with basement storage space below)
Additional wishes/features/daily routine, including reasons why something should or should not be included: living floor must be on the lower level for direct garden access
House design
Who created the plan:
- Planner from a construction company
- Offer for the house (including painter, flooring, and preliminary material selection): approx. 320,000 EUR
What do you particularly like? Why?: like the lower floor; open space, room sizes fit well
What do you dislike? Why?: children’s room next to the garage
Preferred heating technology: air-to-water heat pump
If you have to give up anything, which details/extensions:
- can give up: –
- cannot give up: room sizes of lower floor; open space
Why is the design as it is now?: proposal from the general contractor (a similar house was recently built) with small changes. Also limited by the set budget.
Which wishes from the architect were implemented? The open space was added
What is the most important/fundamental question about the floor plan in 130 characters?
How can the ground floor be changed so that the children’s room is not next to the garage? I can’t find a suitable solution with the current plan. The staircase cannot be moved due to the basement (the guest toilet and utility room would otherwise become too small).

Could you explain in more detail what you mean by the windbreak area? I’m not sure if I understand it correctly.
If I remove the air space and then put a door next to the stairs, it would be completely dark behind it. Also, there would be a door there, but right next to it, the stairs to the back would be open.
Maybe I’ve completely misunderstood it.More or less, you have understood it correctly, regardless of the fine-tuning that the floor plan might bring.
It is what it is: a house needs space at the entrance for a coat rack, jackets, bags, and shoes. I would say at least 60 cm (24 inches) width per person.
Without a wardrobe closet or cupboard, the entire hallway will become cluttered. There is no other space to take this from except the redundant air space.
How do you imagine coming home? Apparently, you come in and admire the view through the panoramic window... jackets and shoes don’t exist in that scenario.
Do you have little helpers who put away your things?
Possible layout without an open ceiling space:
I would relocate the entrance so that visitors don’t immediately enter the private area when ringing the doorbell. However, I can’t position the entrance directly on the garage side because then the bathroom wouldn’t have a window. So, you would first have to walk past the bedroom window – hmm.
Instead of a dressing room, I would plan a walk-in closet with frosted glass doors, since the garage side doesn’t allow for a window.
With the separate entrance, the private upper floor is somewhat more shielded.
The cardinal directions are also difficult to incorporate. Unfortunately, the children’s room is only on the north side. @kbt09 @ypg Do you have any other ideas?
Edit: Ah, @face26 That’s not bad either! However, then there would be a child’s room next to the garage again.

I just realized that I forgot to mention that the walk-in closet is not a must-have. That was more of a suggestion from the general contractor.
If a standard sliding door wardrobe fits easily into the bedroom, that works fine for us as well.
But the last proposal really looks reasonable, even if in this case we would have to give up the open space above the door.
@face26: As I mentioned before, what would actually bother me here is that without the open space with a window behind the door, it would be pitch dark. So that is rather not an option. Still, thanks for your efforts.

On the one hand, I am completely unfamiliar with the plot (someone might think of placing the garage on the left side of the plan), and on the other hand, I don’t believe people would give up their beloved open space with panoramic windows within half an hour just because a forum suggests it.
