ᐅ Is the option for an extremely large lift-and-slide door system structurally feasible?

Hello everyone,
We are building a house with a developer and are currently selecting the specifications for the windows and patio doors.
The living room has a very large window area, approximately 4.80m (15 ft 9 in) wide and 3.40m (11 ft 2 in) high.
The building specification includes a total of 8 window and door elements - four large elements at the bottom with two tilt-and-turn doors in the middle - and four smaller elements above with two tilt windows in the middle.
Since the two tilt-and-turn doors open far into the living room, making furniture placement difficult, we have already been offered, as a special request, two central sliding doors (see plan).

Our preferred option:
However, when looking at the future walking paths from the living room out to the garden, a central opening is not practical for us, as furniture will be placed there. We need side openings (from the outside viewed, on the left at position 1 and on the right at position 4), so essentially two “reversed” sliding door elements.
Or just one sliding door on the far left and the rest fixed.
According to the window manufacturer, this is not feasible for structural reasons.
I drew how I imagine it— is this really not possible? What do you think?

Thanks in advance for your replies.
Best regards,

He didn’t offer us either of the two options described. We can only speculate why—not something we will ever find out.
Why, what, how... if you don’t ask, you remain uninformed (Sesame Street). It always takes two to make it rude not to explain something to a customer...

@SuziundMike, it would be nice if you could briefly share which option you chose, since many people have put a lot of thought into this. 😎
There is nothing to "show" yet, as the house is still under construction.
We have decided on the option stated in the building specifications and thus included in the purchase contract.
However, we moved the tilt-and-turn doors to the exterior side.
