As always the Londonist has some great stuff. Today this appeared in my timeline allowing you to search the database of listed buildings anywhere in England. Some cool entries for SE23.
For instance, I’m sure many knew the Capitol was a Grade II listed building. But did you know the red telephone box almost outside the cinema is also a Grade II listed building? According to the database this is a K2.
Telephone Kiosk. 1927. Designed by Giles Gilbert Scott. Cast iron. Square Kiosk of K2 type with domed roof, perforated crowns to top panel and glazing bars to windows and door.
