House design
Who designed the plan:
- Planner from a construction company no
- Architect no
- Do-it-Yourself yes
What do you particularly like? So far version no. 4, generally the room layout, garage with access to the house
Why? Previous living experiences
What do you not like? Open
Why? Open
Price estimate according to architect/planner: open approximately 500k +
Personal price limit for the house, including equipment: 650k
Preferred heating technology: combined heat and power plant or geothermal heat pump

If you had to do without, which details/extensions
- can you do without: dressing room in the bedroom
- cannot do without: open living area

Why did the design turn out as it is now?
House ideas, restrictions, specifications, own design

Technical room is still to be placed in the upper left corner of the garage (4m wide 2m length)

What makes it, in your eyes, especially good or bad? Open

What is the most important/basic question about the floor plan summarized in 130 characters?

Which areas could be optimized?

Hm .... dimensions on the house?

Style should be clarified ... bay window and shed roof don't fit. It should possibly also be clarified whether 6.5 m eaves height is sufficient. Could be critical towards the garden.

Rooms should be furnished ... especially the living area with the stylish bathroom in the middle.

Where was the technology supposed to go again? Does the 3 m distance to the neighbor still fit?

North arrow on all plans avoids having to search for such information first and then constantly convert it mentally. Official site plans are also usually oriented north.

I don’t understand the draft. A shed roof with a continuous dormer is supposed to reach a maximum of 6.5 meters? That will be much higher given the width of the house. And if you need windows there, you don’t plan this kind of shed roof.
What do the windows in the upper front illuminate? The attic, which is outside the 6.50?

2D does not match the idea of the 3D view.
An upper floor with a roof is much narrower in use anyway.
Then there are things like arbitrary exterior walls without any rules, bathroom in the living room, mini dressing room where no wardrobe fits.
The Ying/Yang children’s rooms are the crowning glory.
And there is the roof pitch...

Sorry, but you have no idea of 3D to 2D. And with 2D there is also a lack of spatial understanding.

This is totally useless.
P.S. I have never written this before!

... the thing with the children's rooms is probably the ground floor ... but you're still right, none of it fits together.

J

... the thing with the children's rooms is supposed to be the ground floor ... but you are right anyway, it all doesn't fit together.

now I see it too
The ridge height may also be 10 meters...
But it is like this: no clear line can cause confusion

But can the high side of a shed roof be called a ridge .. at least the way it is planned?
