I had a meeting in Camberwell which meant that I took the Overground to Denmark Hill, a surprisingly grand Victorian station with passing wagon lits:-
I was able to walk through the leafy late Georgian streets of Camberwell Grove, begun in the 1770s and with a few eighteenth-century houses surviving, and the grand terrace at the north end of Grove Lane:-

An eye-opener, like so many of your posts.
Your focus was farther back, architecturally, but The Salvation Army’s William Booth College building (https://www.salvationarmy.org.uk/william-booth-college) almost opposite the station is a thing of wonder, designed by Giles Gilbert Scott, and reminiscent of his later Bankside Power Station. Interesting that it’s located in Denmark Hill, rather than in Booth’s original Whitechapel stamping ground.
Yes, I did (half) admire it – particularly the statue of Booth, which is so much better than the recent one in Whitechapel – and didn’t know it was by Giles Gilbert Scott. Charles
