Why is the design as it is now?
After countless drafts, we have now really fallen in love with this rough concept.
A mix of many examples from various magazines...
What makes it particularly good or bad in your opinion?
The plot offers a great view to the south.
So far the unknown factor is the neighbors’ development. We want to plan so that it does not really matter how they build without restricting us much.

What is the most important/basic question about the floor plan summarized in 130 characters?
Of course, we would like some basic suggestions about the floor plan.
Too small, too large, senselessly planned...

We have tried to create simple structures. We don't need any special frills.
The main living area will be the primary room.

Do you think the children’s room sizes are sufficient? How is the lighting there? The windows were just roughly drawn in. Should / must skylights still be added there?
Before we add all the furniture, we would like to know in advance if the basic planning could work.
We have already placed the little house (still with rotated ridge) on the plot.

We are already looking forward to an engaging discussion and are open to every suggestion.

Best regards,
Matthias

PS: Just noticed I forgot the window in the dressing room; of course, it will be added later.
