It seems a bit mad that those four steps even exist. What are the spaces on
either side of them?

The problem at Hainault is that the Central line runs on an old viaduct built
for a little-used Great Eastern branch line. The following shows the original
tiny building:

Much of the modern station has to fit between the arches of the old viaduct
and the main road that now runs past the station, so the site is very
constrained:

Horizontally constrained, i can see. Is it vertically constrained? What
prevents the higher floor in the original photo (the link to which has
since been trimmed) being 67 cm lower, so there is no need for steps down
to the lower floor?

It looks like the higher floor is a cross-passage running between a ticket
hall and something else, which also receives steps down from the street.
Making it four steps lower would mean adding four steps to the staircase
leading from the street, which would in turn mean shuffling the passage a
metre or so further away from street (to the left in the photo). What's at
the other end of the passage? Could that also be lower?

The additional steps would then protrude into the cross passage which,
as you say ...

which would in turn mean shuffling the passage a metre or so further
away from street (to the left in the photo).

The passage passes through one of the quite narrow arches of the
original Great Eastern viaduct, so it couldn't be moved left - it would
have to be reduced in width by a metre or so, which I guess would be
unacceptable from the point of traffic flows in the rush hour.

What's at the other end of the passage?

The arrangement is a mirror image of the near end. The rising staircase
at the near end of the passage provides access to platform 1 and the one
at the far end provides access to platforms 2 and 3.

Those steps coming down in to the passage are from the platforms! This
is all ancient infrastructure (the old viaduct mentioned above) and
there would presumably have been no way to move the passage without
destroying and rebuilding everything. Look at the other photos linked
from

all old infrastructure, there is no sensible way to move the passage.

Aha!

Yes, absolutely. I now understand the constraints - thank you all for
explaining them.

It is probably JUST about worth going to Hainault to see that lift
number 3. It is a normal lift, but you must press the up-or-down
button and keep it pressed as you ascend/descend. On the train to
return, in the last carriage, there were two people in wheelchairs -
so it had done its job!
