Two doors to the hallway touch each other

A DH or RH floor plan is often like Tetris.
The alternative is obvious: door from AB into the room. But the OP does not want that. So ultimately it is the OP's decision.

I completely agree with you. The alternative would really be an 87 cm door, in my opinion a stroller would also fit through (though I must admit I don’t know about twins).

I only said, it is not tolerable for me in a new building,

Oh? - but it read somehow differently:

generally doors are [B]not allowed[/B] to slam into each other in a new building.

Yes, and? Where is your problem again? If I am building/planning new, then the doors shouldn’t slam, right!? And still not acceptable!

Yes, and? Where is your problem again? If I am building/planning new,

I have no problem, you have one - which is also okay - but the question was whether the DIN has one.

So I'll say it straight away: as a blonde female, in case of fire I would most likely NOT take the escape route through the narrow hallway and two doors starting from the living room, but simply run outside through the [most likely existing in the living room] patio doors.

But that may be the simple and probably not very DIN-compliant blonde solution.

From a planning perspective, I find this door completely useless anyway and would dispose of it exactly there. Agree with the [GU] that they make a nice opening from the frame and they can keep the door for the next construction (I would find simply taking the door off the hinges silly, because then you always see the hinges).

But that may be the simple and probably not very DIN-compliant blonde solution.

After all, evolution gives blondes the certificate of being more robust than the theorists - at least in case of fire.
