Finalization of floor plan bungalow 130m² for 4 persons

Please do not be unsettled because of the doors. If Yvonne says she would like it this way or that way, you have to ask yourself, am I like her? Etc. pp. There is objectively no right or wrong, only subjectively fits us or does not fit us. My wife and I also live in a bungalow and rejected all doors opening outwards against the contractor’s initial draft except one from the living room, but we installed a real back door to the utility room. Because we would never think of walking onto the terrace from the bedroom or office. We wouldn’t. Yvonne probably would. And you? K.

but you referred to the sliding door on the south side of the living room, right?

The answer "or" is correct
I had advised you to use a ventilation sash in the form of a classic casement window within an otherwise fixed element, and I am advising the same here again. To avoid seventy-some different window widths within a facade, I had advised you to make the fixed glazing width identical to the width of the next adjacent divided element and only give the "rest" to the casement sash, which is completely sufficient for ventilation purposes. Even a maximum elementary school student would find it enough to climb through.

Now the general question arises for me whether a sliding door should visually/practically give way to a terrace door of the same width

No, I advise you similarly to above - only here the opening sash has priority, so it should have an optimal passage width of about that of a 113 cm window door and also be recommended as a standard tilt-and-turn. So the same thing in green, only not with the "rest," but with a defined measure as width.
