No, it's to do with ventilation.

Underground Lines.

That was the case when the ELL was part of the network. Now Bakerloo,
Central, Circle, Jubilee and Northern lines all connect with all others.

The font he came up with is still in use today.

No, it's been modified to form New Johnston Font.

(Bank, Bethnal Green, Chancery Lane, Gants Hill, Notting Hill Gate)

NHG might not a surface entrance building, but it has a rather large
roof on the circle platforms clearly visible from above.
