I think this may be a remnant of St Raphael's Church, whose adjacent almshouses for aged seamen are now the site of the flats at Perret's Court, just to the left there.
Ah! Yes, according to ChurchCrawler:
1853-9 by Henry Woodyer, closed 1878 following disapproval of the bishop and not reopened until 1893. Some war damage, the church was again closed and became part of a factory in 1953 and demolished 1954. Part of the W front still stands in the garden between two blocks of flats.
