I like a bit of 1930s - like many. If you ignore the tatty state of this building and redressed the Lloyds frontage, put back the windows that I assume were originally there, and removed the blue porch, it could easily fit along some Metroland station approach in north west London.
And maybe that's where it should be. Perhaps, and rather unfortunately, what we have is a decent enough (no more than that) building in the wrong place.
Does that make it worth saving versus the Peckham Vision plan for the Plaza/Gateway?
That really depends how far back we want to go to get to where we want to be (and also on where we want to be).
(PS This above is a comment about the buildings, not the livelihoods/businesses of those inside, btw. )
