ᐅ Floor plan for a house on a hillside (ground floor and basement living area) with a maximum of 150 m²

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).

Still the straight staircase, but with the living room and office swapped, eliminating the traditional hallway and thus creating more living space.
Entrance area remains the same, children's rooms are unchanged, optionally a walk-in closet if desired. Large utility room, kitchen can be expanded. Well, then.
However, the house was shifted slightly backward and the garage moved forward. The plot measures 20 x 35 meters (66 x 115 feet), as stated; no further details provided by the original poster.
It is also worth considering whether to create at least a seating area on the south-facing garden.

Floor plan of a building section with exterior walls, red stairwell, and Ram 1/Ram 2.
I could also imagine a staircase like this. With a maximum house size of 150 sqm (1,615 sq ft), it’s important to carefully consider any hallway space that might be wasted.

Thank you for the feedback.
I currently do not have any documents related to the plot. However, there are no special conditions. The only road runs parallel. The slope descends evenly.
I am concerned that moving the garage forward (or the house backward) will significantly impact the construction costs. But I will clarify that. This definitely provides more options since a window in the room next to the garage becomes possible.

What about the staircase... is it an absolute MUST right now?

No, but according to the general contractor, this is the most cost-effective solution.
The staircase material must be either concrete or granite bolt staircases. In this case, with the straight staircase, it was the latter.
And yes, we know that the granite one is more expensive...

Yes, for the price of the "staircase" element – but not for the floor plan.
