Floor plan optimization - semi-detached house approximately 150 sqm

...And anyone who deals even a little with design issues in house construction, or even just with living itself, immediately sees the mistakes in the 2D plan.

My goal was to save the participants time so they wouldn’t have to respond to things that are already fixed anyway

where a garden is located

That is not at all relevant to my question.

That is utter nonsense and the reason for your frustration. You want to quickly discuss a crazy idea without any basis, where we waste time and brains? Okay, here is an assessment of your messing around:

General: The ground floor and upper floor dimensions do not align. So that's already straight into the bin, unless there is a 12 (!) cm setback on the ground floor? There is a basement on which it is built? Where is the access to it? Is the staircase exactly aligned? What kind of roof is on the building? How high are the story heights? What does the development plan say about it? How thick and of what material are the exterior walls with regard to the energy saving ordinance? Staircase relatively too large.

Ground floor: Upon entering the house, you run into a corner. The kitchen-living area is too tiny for 4 people as the main living space. The table blocks the exit to the (imagined) terrace which may be there. You can hardly sit there either; the chairs by the terrace door are certainly unusable. The pantry is too narrow to place any shelving. Complete waste of space. Please furnish the guest room! Totally unsuitable as a bedroom for a later separation (which is nonsense anyway). Bathroom proportionally too big. Why is the washing machine there if there is a basement?

Upper floor: Long dark narrow corridor is questionable and ugly. Bedroom very cramped. If you open the wardrobe door, you fall onto the bed. Dressing is only possible individually and only with acrobatics. Drainage of the toilet could be interesting.

Also: Where is south? Depending on that, the children's rooms or the kitchen-living area are rather dark.

Hello Klein und Fein,

my tip from painful experience. Start with the stairs. They determine the entire floor plan. And a small hint, a landing staircase consumes an incredible amount of space. I would choose a space-saving half-turned staircase.

3. If it was your idea, it makes me sad that you don’t see how paradoxical some things are. You think you can play the expert and are playing with an amateurish idea in the expert league.

A house is planned and the rooms are not arranged along a corridor. Measurements are taken so that rooms can also be furnished according to their use. You don’t put a toilet in the very small living room corner, no dining door opposite the bathroom door, a bathroom on the ground floor has the character of a bathroom in a 1960 agricultural operation, children’s rooms are not only located in the north but also get the 90 “low” window with an extra high sill so that they surely get to know the dreariness, while the bedroom upstairs has a 4 sqm window facing south that basically burns away. The corridor window upstairs is placed arbitrarily, the corridor leads to nowhere. The front door makes furnishing the niche difficult.

And why should a forum or every user who speaks up now praise this program drawing and consider it good when it is not good? Even the measurements used are not considered and ground floor/upper floor are not congruent. Since you withhold important information, there is no cleverness or flash of genius from the forum either. That’s just how it is... No arms, no cookies I already mentioned. It may also be that you simply do not understand it.
