The vehicles are driving on the left side of the road, and the yellow rear license plates are characteristic of the United Kingdom. The architecture features classic white stucco terraced houses, which are very typical of affluent areas in London or similar British cities. The road markings and the style of the green construction barriers also strongly point towards a UK setting. The overcast sky and lush, mature vegetation match the temperate climate of Southern England. I suspect this is in a residential area of London, possibly near Hampstead or a similar neighborhood. I am fairly confident in this assessment.
