IIRC, that can be acceptable if there is only one room in the loft, and

It's not really. The stair itself needs to be separated by a full
height enclosure with a door at the top landing, or separated from the
floor below by an enclosure and door at the bottom.

Would not a hall/landing that has all rooms that open on to it protected
by fire doors not count as such an enclosure?
