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

Um, for what exactly?

Think carefully about what room sizes are considered "normal" for each type of room. For example, a bedroom for two people under 13 m² (140 sq ft) is, in my opinion, always too small. If the office is ever intended to become such a bedroom, it is therefore too small. Or is it already clear that only one person will sleep downstairs later on? (One might suspect there’s more to that...)

Both our living room and kitchen doors open outward (into the hallway); both doors are basically always open. It doesn’t bother us that they open into the "circulation space hallway." We only use the hallway to put on jackets and shoes, and the open doors in the kitchen and living room do not take up any usable space.

The doors even swing into each other when open... another design flaw. But a clever person came up with door stoppers for this.

The kitchen – dining/table – living room form an L shape. There is also a door between the dining/table area and the living room. The living room is on the short leg of the L. When all doors are open, you can walk in a circle.

Thank you for your input.
I have now made the house on the plan a few centimeters longer and wider; the "office" now measures 3.36 x 3.26 meters (about 11 ft x 10.7 ft), which is nearly 11 m² (118 ft²).
One side should still be at least 3.45 meters (11.3 ft) long to fit a large closet as well (which we currently have).

Unfortunately, I won’t be able to upload the new plan before Saturday.

Sorry, I don’t mean to offend you. But I’m afraid the whole thing is so underdeveloped that it’s hardly worth discussing.

Then try furnishing it with a double bed.

Mattress = 200 cm (79 inches), with bed frame at least 210 cm (83 inches). There are 326 cm (128 inches) available, and a wardrobe still needs to fit in. I always calculate a Pax wardrobe with sliding doors as 66 cm (26 inches).
210 + 66 = 276 cm (109 inches), leaving 50 cm (20 inches) of hallway space in front of the wardrobe, minus plaster, etc., since 326 cm (128 inches) is the raw structural dimension.

And, as mentioned, the small ground-floor bathroom doesn’t work anyway, so it really makes no difference to add 10 cm (4 inches) of wall thickness here or there—the concept needs to be changed.

Here is my current bedroom; I even made the bed specially.
Width 347cm (137 inches). Bed – walkway – Ikea Pax wardrobe.

I will solve the toilet issue by swapping the shower and the toilet.

Bedroom with bed, large window and view outside, wardrobe visible.
