Hello dear community,
We are planning to build a single-family house next year and believe we are ready to have a permit plan created.

The plot is 21m (69 feet) wide and 31m (102 feet) long.
The groundwater level is very high, so no basement.
The zoning regulations require both the house and the garage to have a gable roof.
The garden is located to the north behind the house; we deliberately placed the terrace on the north(west) side because we both prefer not to be exposed to the sun for long periods.
25 cm (10 inches) bricks + 20 cm (8 inches) insulation.
The house will be heated with geothermal energy (KNV Topline 1145) using a trench collector system.
The garage will be built without a door, essentially as a carport, allowing side access to the main entrance.
The roof above the mechanical room (in the attic) will simply be extended.
The guest toilet/bathroom on the ground floor will partially fit under the staircase.

Zoning restrictions/requirements: gable roof, eave height 5m (16 feet)
Plot size: 650 m² (7,000 sq ft)
Slope: no
Floor area ratio: 0.3
Building envelope, building line and boundary: 3m (10 feet), garage recessed 5m (16 feet)
Edge development: my "garage" adjacent to existing neighbor’s garage
Number of stories: 2
Roof style: gable roof
Architectural style: rather modern
Orientation: south-facing if possible
Maximum heights/limits: 5m (16 feet) eave height/roof edge

Homeowner requirements
No basement (due to high groundwater)
2 people (planning for 4)
Office: only intended as a storage room/guest room, for future needs

House design
Who designed it:
I designed it myself
We planned the kitchen in the “niche” so it is not the center of the room when entering and because it faces the street, letting us follow what is happening outside a bit.
The living room is on the darker north side since light from the south or west can be distracting when watching TV on the couch (as it is currently).

Thanks in advance,
Christian

The long hose from the entrance all the way to the kitchen is extremely impractical and sure to cause frustration.

I don’t understand why some people want the kitchen as close as possible to the garage or entrance door. Whether I carry the bags 5 meters (16 feet) farther or less doesn’t make much difference... Some people live on the 4th floor without an elevator, and that’s a bigger challenge. My floor plan was also criticized for this, but I didn’t let it bother me. I carry bags along that route 2-3 times a week now, and it’s not an issue. Placing the kitchen in the north, far from the living or dining room, isn’t ideal either. Then instead of carrying groceries every few days, you end up moving plates back and forth between rooms daily.

Regarding the kitchen, I would rather consider whether it really needs to be separated from the pantry. In my opinion, I would prefer continuous cabinets here, invest a bit more in the kitchen, and store canned goods and similar items there. It probably looks nicer than a tiny corner and offers just as much space.

Best regards,
Michael

My post was not primarily about the long hallway, but rather the narrow corridor with a small door and three turns. In such a layout, people are more likely to get in each other’s way, and so on.

First of all, thank you very much for the almost exclusively constructive feedback.
Apparently, something was misunderstood or I formulated it poorly: I will of course hand over my draft to an experienced planner at the end, who will then discuss and adjust with me any poorly placed walls, doors, etc.
I was expecting suggestions and experiences from you here and, in my opinion, I have already received quite a bit from you—thanks again for that.

Regarding the points mentioned:

The knee wall will settle between 1.40 and 1.50 meters (4.6 and 4.9 feet); the exact height will be determined by the final floor construction.
I have uploaded a cross-section of my building model for this (the upper floor will have a ceiling height of 2.60 meters (8.5 feet), which differs from what is shown in the image).

The time mentioned for planning was mostly used for idea development; I have not yet paid enough attention to details or I forgot some (e.g., the washbasin in the WC).

For the pantry, I will definitely consider switching to a "furniture variant."

I deliberately planned the door from the living area to the corridor this way because it is supposed to remain open most of the time and only be closed in the evenings to reduce noise.

I will probably have to accept that the shower under the stairs is not feasible, but hope dies last.
In that case, I would swap the shower with the toilet and forgo the window in the WC (a mechanical ventilation system is planned anyway).

I had not considered the doors and space for cabinets behind them—very good point.
I did not plan the kitchen sink under the window anyway.

I will also give some thought to the "narrow" corridor and possibly design the house a few centimeters wider.

The key issue here is that the shower and therefore the bathroom on the ground floor do not function properly.


Since it is supposed to be a spiral staircase, the shower will have to start around step 8 to 10 at the latest. I only have the standard section available now:

Technical drawing: Sections A-A and B-B with staircase and dimension details.


However, with a closed concrete staircase as needed here, as well as the wall next to the toilet, the height for the shower at the starting area would be about 170cm (67 inches) max.

Since the bathroom is also an important point, simply adjusting a window or a door is not sufficient.

Apparently, you want to create a complete living unit on the ground floor for when you’re older. In that case, I would expand the space here and reduce the square meters upstairs. What speaks against sleeping downstairs from the start and sending the kids upstairs by themselves?

What are you actually planning to do with over 28m² (300 sq ft) of storage space in the garden? Do you have a boat or something?

What do you actually do with over 28m² (300 square feet) of storage space in the garden? Do you have a boat or something?

That is the cellar replacement room.
Even with 28m² (300 square feet), I’m afraid it will fill up pretty quickly.
(Lawn mower, bicycles, car tires, tools, workbench, patio furniture, etc.)

The room on the ground floor is intended to be used for that purpose as long as there are children in the house, meaning as long as a lot of space is needed in the cloakroom.
