I'm an infrequent visitor to SE23 forum, but this thread is very useful.
I live in a house very nearby that would be affected by the development.
I've just sent an objection on the grounds of light, privacy, and parking, as well as responding to some of the assertions in the Design & Access Statement, referencing recent statements by Greg Clark and noting today's tree-felling.
Thanks to all who gave tips and advice here - it really helped.
