We passed one of my favourite modern buildings in Rotherhithe, just on the outskirts of Rotherhithe village, behind The Ship pub: the Thames-facing Princes Tower (which at some point seems to have been re-named Riverside Apartments). Its address is 97 Rotherhithe Street, SE16 4NF and it sits on the site of the old Prince's Wharf and Prince's Stairs. at the start of Elephant Lane.
In the 1850s Prince's Wharf was the timber-built base of a barge and boat builder, but by 1873 the entire Thames frontage at this point was made up of a series of wharves of varying sizes. By 1937 Prince's Wharf was a six-storey brick-built wharf next to Gordon's Wharf and linked to it by walkways. Both had been operated as granaries by Gillman and Spencer, which specialized in landing and bagging loose cereals and the manufacture of flaked maize and brewers' preservatives, but when the company was purchased by Pauls Malt Ltd in 1902 they also manufactured a product called Kositos, an animal feed.
Update: Quite coincidentally, I was trawling through the planning proposals in Southwark News today (3rd July, only 2 days after my original post) and I noticed that there was a planning application (ref 13/AP/1454) to add additional accommodation to Flat 6 Princes Tower. Without knowing where the flat is in the general scheme of things, it's difficult to form an opinion, but it does seem a shame that the building isn't Grade 2 listed, so that this sort of application has to go through more rigourous checks.
