Hello everyone,

We have already made good progress with the floor plan for a single-family house (see image of the ground floor).
A friend of ours mentioned that the corridor leading to the kitchen/living area on the ground floor, with rough construction dimensions of 1.07 and 1.16 meters (3.5 and 3.8 feet), seems too narrow from his point of view. He suggested that we should make the house at least 25 centimeters (10 inches) wider to allow more space here. However, we would prefer to avoid this with regard to costs, as the house, measuring about 9.0 x 12.5 meters (30 x 41 feet), is already quite large and fully covers our desired room layout.

Do you see any significant reason to consider that the corridor width in the hallway is too narrow and that we should revise the plan?

Many thanks and best regards

Thank you, I will upload the complete floor plan including the questionnaire tomorrow. Then I would be glad to discuss everything together again.
Wow, that’s bold.

Great if you can set everything up.

Do you want the kitchen as shown in the drawing?
Why is there a maze of cabinets in the hallway? Is that space needed for shoe and handbag storage?
Why is there a bathtub on the ground floor? Or is that supposed to be a narrow, long shower?

I also consider the size of the landing staircase to be borderline. Only about 275 cm (108 inches) depth... from my sample staircases with a floor height of 285 cm (112 inches):

The staircase definitely needs to be reviewed, otherwise the hallway will become even narrower.

@ufr123 ... don’t forget the site plan and north arrow

So, I tried to compile everything below.

Development plan / Restrictions
Rear property with slope descending from the street side (see cross-sections). Basic zoning plan from the 1970s. No restrictions regarding building envelope, plot ratio, or floor space index.
Total lot size approximately 730 sqm (7,857 sqft), including an 80 sqm (860 sqft) driveway.

Client Requirements
Single-family home for four people (2 children), with a dedicated office for each parent. Separate walk-in closet not integrated into the bedroom. Spacious guest room in the basement, as grandparents often visit. Space for a sauna in the basement. Sufficient space in the hallway for shoe cabinets, etc. No open-plan layout, so at least the kitchen should be separated.

House Design
Designed by architects. The requested room program was implemented; however, the hallway on the ground floor appears too narrow. A "critical" point in the planning process was the north side of the upper floor, as several rooms and sufficient space for a "T" shape in the bathroom were required there.

Why was the design developed the way it is?
Individual planning together with the architects. Various options were discussed and the plan was gradually adjusted.

What is the key/basic question about the floor plan summarized in 130 characters?
How can the “hallway” area, especially the ground floor layout, be redesigned to avoid dark corners and ensure wide enough passageways? There should still be enough room in the hallway for several cabinets. Additionally, a staircase with a landing or at least a non-winder staircase is preferred. Exterior dimensions of the house (e.g., 25 cm (10 inches) shorter and 25 cm (10 inches) wider) could still be adjusted, but we would like to keep roughly the same total footprint. The length of 12.50 m (41 ft) is due to fitting multiple rooms on the north side of the upper floor (bathroom, walk-in closet, bedroom), and the lot favors a rather elongated house orientation.
I appreciate honest feedback on all points you notice!

The kitchen layout was done by my wife, similar to our current kitchen, which she considered "optimal."
The "wardrobe maze" resulted from my wife’s wish for enough storage space in the hallway. However, we definitely won’t need as much as shown. It is also a remnant from an earlier design phase where the hallway was arranged differently, and the wardrobes were connected to a laundry chute.
The ground floor bathroom has a shower that is 75 cm (30 inches) wide.

The staircase urgently needs to be checked, otherwise the hallway will become even narrower.


The staircase is planned with a 17.9/27 rise/run ratio for a floor height of 2.5 m (8 ft 2 in). With a 28 cm (11 inches) run, the hallway would indeed be even smaller. Due to the issue with the hallway width, we have already reduced the originally planned floor height from 2.61 m (8 ft 7 in) to 2.50 m (8 ft 2 in); otherwise, we would have needed an extra step or the staircase would have been designed with an 18.5/26 rise/run ratio (which we find too steep).
