I've seen the plans for this, although unfortunately can't find any
pictures online. Plans are the the Lewisham Library for inspection
(ref DC/04/58571). The deadline to get comments in is tomorrow,
though, so be quick!

Basically the plans involve:

1. Demolition of the current station buildings at street level (and, I
think, at platform level but am not 100% sure of this).

2. Creation of a new ticket office at platform level on the south side
(i.e. going towards central London), and a modern, Fosteresque glassed
waiting area at platform level which will be visible from the street,
to improve security.

3. Restoration of the carriage ramp so people can walk along it to
gain access to the station.

4. The creation of a piazza in the area bounded by the High Street,
the current station and the carriage ramp, with cafés and other
businesses housed in the arches of the viaduct and the ramp.

5. Access to the platform for Dartford-bound trains will be through
one of the viaduct arches and up a flight of stairs, although there
will be full disabled access to both platforms.

It all looks well and good on paper, and basically seems like a good
plan. The only flaw I could see, though, was that it doesn't get rid
of one of the basic problems of Deptford Station, which is separate
access for the two platforms, meaning that it's not feasible to
install ticket gates. The reason for the ticket office being at
platform level on the London-bound side is to increase security, but
surely if the ticket office isn't going to be attended from first to
last train that's not a consideration, and if it is going to be
attended all the time, why not locate it at the bottom and create a
single entrance with ticket gates? Ticket gates would surely help
improve security at platform level.

I've fed that back, anyway, so will be interesting to see what the
response is!
