Floor plan design single-family house 150 sqm - tips for improvement?

... well, it wouldn't be that big if the parent wing was upstairs...*duckandrun*

... then go ahead and draw the rooms upstairs in a single-story design!

I would have a normal gable roof house like Schwörerhaus Plan E 15-143.16 or 15-149.10 or Balance 250 from Weberhaus

Or a bungalow with 2 rooms under the roof
Schwörerhaus Plan E 15-211.1 but smaller

I would also first think of a bungalow with a converted attic. The roof terrace is really useless. Apart from the fact that you don't use it when you have a terrace, you sit there like on a show tray. Who wants that?

Apart from not using them if you have a terrace, you’re sitting there like on a silver platter. Who wants that?

I learned here that with the right elements you can create a small castle style!

A roof terrace can be very nice if you do it right!

The balcony is there now, so should I not use it according to you?

It's not gone yet - the chance to omit whose meaning one has to drink oneself into is still available

Why do you actually want to "omit" the area above the living room on the top floor, and not, statically more advantageous, the one above the master suite?

He’s not there yet - the chance to omit whose meaning one has to get drunk to accept is therefore still given

As I said, just show me other options, then no one here has to get drunk voluntarily!
