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).

I just realized I forgot to mention that the walk-in closet is not a must-have. That was more based on the general contractor’s suggestion.
If a standard sliding door wardrobe fits easily in the bedroom, that’s perfectly fine with us.
But the last proposal does look really reasonable, even though in that case we would have to give up the open space.
@face26: As I mentioned before, what bothers me here is that without the open space with a window behind the door, it would be completely dark. So that option is unlikely. Still, thanks for your effort.

It can be done with glass, but it’s not ideal. I would go with the suggestion from @kaho674! For me, it’s important that this has a small entrance area or vestibule in my view.

By the way, I would swap the washbasin and toilet in the bathroom on the basement level. Also, the dining room on the west side would have many more windows.

In the basement level, it would be a good idea to relocate the WC door to create a built-in wardrobe along the lower wall of the hallway, spanning from wall to wall.
Additionally, an exterior door from the utility room to the cellar replacement room could be added.
For a hip roof, skylights or roof windows can also provide natural light.

In the basement level, consider possible uses for the roughly 11 square meter (118 square feet) hallway... If you swap the guest room and living room, and do some rearranging... Place the WC between the guest room (upper right in the plan) and the utility room (lower right in the plan), resulting in a 3 square meter (32 square feet) hallway, with the staircase next to the dining area... kitchen at the top of the plan...

Currently, the kitchen is not exactly ready for a three-course meal.

So far, we have been quite satisfied with the basement.
Swapping the toilet and the washbasin is a very good idea.
The utility room will get a door to the cellar replacement room.

I guess I lack the imagination for the rest of the basement.
The large hallway is also due to the fact that the possible rooms at the bottom of the plan are limited (because they are completely below ground level).

You can do without a hallway if you arrange the rooms differently.

I have already understood that.

Alternative:
pros: Main entrance next to the garage, optional separate upper floor with door, more sunlight for children, larger kitchen, 2m (6.5 ft) wardrobe cabinet plus shoe cabinet
cons: Bathroom above living room – drain must be well insulated – thick wall at the stairs already planned – should work. Roof window in the upstairs hallway is necessary.
