If you have to give up, which details/upgrades
- can you give up: large garage
- cannot give up:

Why is the design the way it is now? For example:
Based on various prefabricated houses, we designed our own floor plan. The study on the ground floor should be large enough to possibly use as a bedroom. The living room faces south, and the children’s rooms are equally sized. The washing machine would go into the storage room.

What is the most important/basic question about the floor plan in 130 characters?
General room layout and positioning? Which knee wall height (1 m; 1.2 m; 1.6 m) would be optimal for space gain, cost savings, and daylight in the upper floor?

Hello,

I hope the notes on the drawings are legible and understandable.
According to the development plan, only a knee wall height of 50 cm (20 inches) is allowed, but according to telephone information, deviations are approved as long as the maximum ridge height is not exceeded.

The drawing does not show any furniture.

The staircase should run straight in the hallway on the west side, so it opens in front of the two doors for the children’s rooms and the master bedroom.

Floor-to-ceiling windows are planned in the south-facing living room; all other windows will be "standard."
The kitchen is planned in the southeast corner of the house, hence the passage to the pantry. Originally, no pantry was planned; instead, there was a large utility room. On the advice of the house seller/consultant, a wall was added there so you don’t walk directly from the kitchen into the utility room.
A fireplace either next to the living room door or on the west wall.
Unfortunately, furniture was not included in the export: staircase runs straight in the hallway on the right side (when entering the house), so you reach the doors of the children’s and master bedrooms on the upper floor.

The current floor plan is based on external dimensions of 10.50 m by 11 m (34 ft 5 in by 36 ft 1 in).

If anything is unclear, please ask. Otherwise, feel free to ask questions or critique. I am not here just to receive praise (although that is always nice), but that’s not the purpose of this exercise.

According to the current measurements, the ridge beam is 30cm (12 inches) from the living room wall towards the terrace. From that perspective, the chimney could be placed "inside" the study room on the living room wall, which would avoid having a stove pipe running through the room. However, you would literally enter the chimney when you open the door. The length of the pipe wouldn’t be any shorter either.
This is typical again. The chimney is planned down to the millimeter, but the staircase doesn’t fit and therefore the entire plan becomes irrelevant.

That's why I'm here—to get notified about such things. Besides, for a beginner, it's easier to decide on the chimney location than to finalize the staircase dimensions.

Yeah, but then no one here reads anymore if you keep coddling stillborn projects.
