This game has been inactive for a year. I must say that it greatly improved my ability to analyze photos for the location.
I recently watched a series on TV that was filmed in London. Since it was streaming, not broadcast, I was able to "rewind" to see a scene again. With just a picture of a building in presumably central London, I was able to locate the exact buildings many times. On occasion, there were hints, like a street sign or a sign of a business but sometimes there was not.
There are just about two buildings left that I cannot yet identify. Anyone interested?
Here's an example that I solved. This building was difficult to find but eventually I found it.
Attachment 17447 Fleet House, Clerkenwell Road, London, EC4
This one, I'm still looking...
Attachment 17448
Hints: It is almost certainly in London. Likely, it is in Notting Hill or Holland Park. Much of the filming was also in the South Bank but that area does not have this type of architecture. I am not completely sure, but I think this is Regency architecture but could be Georgian architectural style.
Notice that it's a detached house, which is unusual in London. The left is not touching another building but the right side might be. If one uses Google Maps at a detailed enough scale, one can see the outlines of houses and can see which ones are detached.
The TV show also showed the interior and the back had a small rectangular swimming pool. However, often the film industry uses different buildings for the exterior and interior so the swimming pool might be a false clue.
Note that in London, many townhouses have black iron railings in front but this one does not. Note that the front door steps have a white handrail that connects with the house.
Also note the Chrysler 300 in the photo but that is British spec with amber rear turn signals and British number plates (license plates) if it is the same Chrysler that appeared in another episode.
