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).

Ground floor plan of a house: bedroom, walk-in closet, bathroom, hallway, open space, two children’s rooms, stairs


Basement floor plan with open living/dining/kitchen, office, hallway, utility room, WC, and basement storage.

Thank you very much in advance for the responses.

The guest toilet will have a light well. The office will have a regular window since the left side is completely open due to the L-blocks.

Katja, I really like your suggestion. We hadn’t considered the recessed wardrobe before.
There won’t be enough space for a bay window, but we will ask the general contractor about the possibility of adding an extra course of blocks to widen the wall.
That might help to create a bit more space.

@haydee:
Thank you for your feedback as well. Your criticism matches my initial impression.
Unfortunately, I have no idea how to separate the bedrooms and the front door/staircase without it having a significant impact on the living area and cost...

Does the house have to be square?
Does the staircase have to be straight?

Kaho is better in this respect.

Also mirror the staircase.

The gallery is removed.
The children's rooms shift forward.
This creates a wardrobe on the left.
A door is placed on the right next to the bottom of the stairs.

Hi,

Remove the air space and instead create a walk-in closet there. Use the extra space gained to move the bathroom upstairs. Use the room in the bottom left of the plan as a cloakroom and give the child back the 1.5 sqm (16 sq ft).

The site plan is missing, but you might consider relocating the main entrance to the left into the "new cloakroom" and make the staircase and hallway lead to the bedrooms. Perhaps just with a glass element or door.

Otherwise, I don’t think it’s too bad.

I think exactly the same.
A vestibule in front of the void. The vestibule is the starting point of comfort in this house... omitting it will cause problems for everyone living here every day.

Could you please explain in more detail what you mean by the vestibule? I'm not sure if I fully understand it correctly.

If I remove the open space and then put a door next to the staircase, it would create a completely dark room behind it. Furthermore, there would be a door there, but right next to it, the staircase at the back remains open.
Maybe I have completely misunderstood it.
