There are three escalators and a staircase on the west side of the
Northern Ticket Hall (NTH), so that's round to the left as you come
up into the NTH from the underground, or immediately on your right
if entering via the subway from St Pancras. They bring you up to
the west side of the semicircular western concourse, (ie as far away
from the mainline platforms as you can get without going outside).

Those look to me as if they emerge "outside". And on my passageway
plans it's marked as the exit to KX-Central (the development beyond
the Gym), not the station itself.

Having now seen the same plans as yourself, I note that you are
talking about the escalators below, not the ones currently installed,
leading to outside.

#If you imagine a u-turn to the left at the top of the northern
booking #hall escalators (just outside the short barrier line)
there's nothing #on the building plans (other than a partition wall)
at LUL booking hall #level, and there's a "National Rail safeguarded
escalator box" in that #position on the ground floor.

The way I'm describing it is that sheet 4 is the ground floor, and the
bank of three escalators is clearly within the boundary of the
concourse, which as can be seen today is at the same radius as the back
wall of the Great Northern Hotel. At 200% magnification, you can see
what looks like a glazed screen enclosing the escalators, with large
openings in alternate bays, at a radius of 62.370m.

I'm sure we are talking about the same ones. In other words:

there's one set of escalators which are there today, and lead to the
outside world with the Gym in front of you.

there will be, one day, a second set leading to indoors (but only just)
of the National Rail booking hall, which will be a "u-turn" to the left
from the current deep-tube escalators.
