[1][2] Building type M10 was generally built as a pair of cores, that is to say that it had two entrance not connected by a corridor.
The kitchens share a back-to-back plumbing riser with the baths, and are accessible only through the living room.
The main entrance to the building is sheltered by a canopy, leading to the vestibule where resident's postal boxes are located.
Unlike the more common P2 building type, the elevator lifts at the M10 were accessed from the mid-landing of the stair which itself was open to the corridor at each level from the basement up to the 9th floor.
Barrier-free access of the basement is accomplished with a set of ramps from the vestibule of the building.
