We’ve got two sets of french doors, one with three glass panels either side one off the living room and they have to be hooked open. If a sliding for can be fitted without a load of complex ironmongery and that looks okay I’d do that if I had My time again although I don’t know how you’d do it with glass walls as we have.
I won’t have bifolders - the family room had them in the plans and we binned the idea after seeing the contents of a garden ( dusty soil, leaves, many flies) get blown into a house elsewhere.
