Site: London stone (2 memorials)
EC4, Cannon Street, 111
Google Street View for June 2016 shows the Stone (well, its cubicle, at least) in the old building. By May 2019 the new building can be seen with a new, very similar, cubicle in an identical position. The Museum of London looked after the Stone and had it on display during the building works.
All this just draws attention to the fact that a near-identical building has replaced the perfectly acceptable 1960s one. It's even the same height, presumably capped by the rules about sight-lines to monuments such as St Paul's Cathedral. In a climate emergency why are we allowing these like-for-like redevelopments, when the existing buildings could be renovated and brought up to present-day specs, without the massive load of embedded carbon?
