I've just spotted this planning application for the old post sorting office on Devonshire Road.

"The part demolition of existing buildings to the rear of 61 Devonshire Road SE23 and the construction of part two/part three storey buildings to the rear to provide 9 residential units and 4 Artist Studios"

It looks like an interesting use of the site (at first glance at least) but I suspect the lack of car parking will be a problem.
