Going nowhere

[ladylouise62]

Just when you think you have found the exit, you find more things stopping you.

This door is in a wall along the side of a road in a busy part of north London. Why was there a door there, and why did it take you from a used (albeit little-used) road to an old overgrown road with a fence behind, when you can walk along either road? ... and what was up there on the right that had to be painted over?
These things need to be answered.

Looks like this side was a small building, perhaps public toilets or a small roadside cafe?

Lol. What a mixture.
May be it was a Abby at some point in time

Well spotted

Would have been a very posh public toilet, Rolf!

I'm inclined to think along more romantic lines - the neat bricks of most of the wall looking Georgian ones, with those chunkier efforts at the top being of a more recent repair (early last century?).

I see the semi-circular opening at the top of the door having held a stylish 'fanlight' over a strong mahogany door. The plaster/cement at the sides having supported Georgian door pillars.

Perhaps the road behind the door was once part of that posh residence - one of the 'Upstairs Downstairs' variety?

Perhaps it is all that remains of an important house after the area had been shelled - or perhaps it was part of a film set, abandoned for ever....
